Description

  The present invention relates to an aluminum alloy stamp and a manufacturing method thereof.

In Japanese society, the role of seals is extremely large. There are various types of seals, from real seals to bank seals and even seals, each of which is heavily involved in the social life of individuals and corporations. Therefore, people are deeply interested in seals, and their preferences vary from selection of materials to the problem of typography and the shape of seals.
There are various materials such as plastics, plants such as boxwood, minerals such as crystal, buffalo horn, etc., but ivory was in practical use as a luxury product.
However, those using plastics or plants may be worn or deformed, and minerals may be damaged. In addition, the use of ivory is prohibited from the standpoint of animal welfare, and the ivory seal is difficult to obtain.
For this reason, titanium seals are also known based on the idea that metal materials have high hardness and excellent wear resistance and are suitable as seal stamp materials. (Patent Document 1) In addition to titanium, a material using a rapidly solidified aluminum alloy as a seal material is also known. (Patent Document 2)

Utility Model Registration No. 3103611 JP-A-10-114131

In a seal stamp using a titanium material as shown in Patent Document 1, it takes time to engrave characters and the like on the titanium material, and there is a problem that vermilion bleeds even though the vermilion paste is good. Another problem is that the titanium material is expensive.

In the seal stamp using the rapidly solidified aluminum material shown in Patent Document 2, the material is hard and it takes time to engrave characters and the like. Moreover, it is a special rapid solidification method and is expensive. It has problems such as weak adhesion such as plating applied to the surface and easy peeling.

In the present invention, an aluminum alloy material obtained by melting is used as a stamp material, and it is an object to provide a stamp that has a high-class feeling, has a good paste paste, and has excellent durability.
In particular, an aluminum alloy material obtained by melting is used as a seal stamp material, and the surface is anodized to increase the hardness and to obtain a material that can withstand use as a seal stamp. Furthermore, after applying an alumite treatment layer to the surface around the seal material, this anodite layer is colored to produce a high-class feeling and luxury, and the anodized layer is sealed to form a colored treatment layer. It is firmly attached to the anodized layer, making it difficult to peel off. In particular, an alumite layer is dyed and a beautiful colored layer is obtained.
The marking surface to be engraved may be an aluminum alloy material that is not anodized, and the state of an alumite treated or further sealed treatment can be freely selected. In particular, with respect to the stamped surface, when the alumite treatment is performed but the sealing treatment is not performed, the surface area increases by about 30,000 to 40,000 times as compared with the case where the alumite treatment is not performed. There is a merit that paste is easy to enter into the gap and glue is good.

In the present invention, the stamp name to be engraved on the stamp includes all kinds of names such as personal names, corporate names, trade names, symbols, and figures. In addition, the aluminum alloy material obtained by melting is composed mainly of an ordinary aluminum alloy member obtained by casting or the like, an aluminum alloy member commercially available in the shape of a round bar or the like from a factory such as a steel mill.

The reapplied alumite layer is sealed, and masking of the seal surface of the seal material is performed. It is characterized by removing.

Invention of Claim 12 is a manufacturing method of the aluminum alloy seal stamp as described in any one of Claims 5 thru | or 11, Comprising: A coloring process is performed to this alumite layer before this sealing process, It is characterized by the above-mentioned. To do.

According to the invention of claim 1, since the periphery of the seal material is anodized, it is easy to touch, is hard to be stained, and has high hardness and excellent durability. Moreover, since aluminum material is used, it can be easily recycled. Processing such as laser processing can be easily performed on the anodized surface.

According to the invention of claim 2, since the sealing treatment is performed after the alumite treatment, the surface is smooth and the tactile sensation is excellent.

According to the invention of claim 3, a high-class feeling and luxury can be obtained by performing the coloring process. At the same time, the colorant enters the fine pores of the anodized layer, and then further sealed, so even if used for a long period of time, the colorant is difficult to jump out of the fine pores of the anodized layer and is difficult to peel off. Difficult to fade or fade. A beautiful colored state can be maintained for a long time.

According to the invention of claim 4, the seal surface is in an alumite-treated state, and the sealing treatment is hardly performed. Therefore, the vermilion enters the fine holes of the alumite layer, so that it is excellent in the paste of the red mark and sharp. A clear seal can be obtained. That is, by alumite treatment of the stamp surface, a large number of nanohole unit holes around 15 nanoholes are formed and the surface area increases 30,000 times to 40,000 times compared to the stamp surface that is not alumite treated. Glue and retention are good, and clear imprinting can be performed.
Furthermore, since the marking on the stamped surface is anodized, the stamped portion is hardly chipped and is not easily deformed. Here, it is explained that the sealing treatment is hardly performed, the anodized layer is made on the surrounding surface and the marking surface, and when the sealing treatment is performed with only the marking surface masked, the anodizing layer on the main surface is It is surely sealed. At this time, the seal surface is masked and ideally not sealed, but in actual processing, when sealed together, the fine holes become slightly narrower, and some fine Since the hole may be blocked, it is said that the sealing process is hardly performed as described above.

According to the invention of claim 5, since the periphery of the seal material is anodized, a material having good tactile sensation and having excellent durability that is difficult to be stained is obtained. In particular, the stamped portion of the stamp name is anodized and hardly sealed, so that the vermilion enters the voids in the anodized layer, so that the stamp is excellent and the sharp and clear stamp is obtained. Furthermore, since the marking on the marking surface is anodized, chipping of the end of the marking portion is unlikely to occur.

According to the invention of claim 6, the marking surface remains the aluminum alloy material and is easy to be engraved.

According to the invention of claim 7, the stamp face remains anodized, and has the same effect as the claim 5, and can finally be engraved with the name of the stamp. I can do it.

According to the invention of claim 8, the stamp surface remains the aluminum alloy material and is easy to stamp. At the same time, the stamp name can be engraved on the stamping surface, so it is possible to mass-produce what is not engraved.

According to invention of Claim 9, masking is unnecessary and an alumite process and a sealing process are easy. The stamp surface can be easily stamped by deleting the alumite layer.

According to the tenth aspect of the present invention, since a stamping surface that has been anodized is stamped, a clear stamp name can be stamped on the stamping surface. In particular, the stamped portion of the stamp name is anodized and hardly sealed, so that the vermilion enters the voids in the anodized layer, so that the stamp is excellent and the sharp and clear stamp is obtained. Furthermore, since the marking on the marking surface is anodized, chipping of the end of the marking portion is unlikely to occur.

In general, when masking an alumite-treated stamp surface, a means for holding a part of the surface around the seal is often provided. In this case, there is a problem that the surface of the alumite treatment layer in the held portion becomes uneven and a clean surface cannot be obtained. According to the eleventh aspect of the present invention, since the alumite treatment layer on the surrounding surface including the held portion is once removed and alumite treatment is performed again, a clean surface can be obtained.

According to the twelfth aspect of the present invention, it is possible to obtain a high-class feeling and luxury by performing the coloring process, and since the colored part is subjected to the sealing process, the coloring material is hardly peeled off, and the coloring is good for a long time. The state can be maintained.

Example 1
A first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the stamp 1 of Example 1 consists of what formed the aluminum alloy base material 2 obtained by melt | dissolution in the cross-sectional circular rod shape. Although it does not specifically limit as this aluminum alloy, AC00, AD00, etc. can be used. For example, JIS standard ACXX (circles are numbers), ADXX (circles are numbers), A5000 series to A6000 series can be used. In particular, those in the A1000 range, A5000 range, and A6000 range are round bars as the material, can be used as they are as the size of the seal, have appropriate hardness, and are suitable for alumite treatment. It is preferable because it is suitable for showing the coloration in the processing clearly.

A stamp surface 3 is provided on one end surface of the seal 1, and the other end surface is connected to a surrounding surface (so-called peripheral surface) 4 by a smooth surface. In the first embodiment, the other end surface is also treated as a peripheral surface. As shown in FIG. 2, all surfaces of the marking surface 4 and the peripheral surface are subjected to alumite treatment to form an alumite layer 5. As shown in FIGS. 1 and 2, the stamp surface 4 is left in the state of the alumite layer 5, and a stamp name 7 such as a name and a company name is imprinted on the alumite layer 5. On the other hand, the peripheral surface and the other end surface (referred to as a peripheral surface in the present invention) are subjected to a coloring process on the alumite layer 5 to form a colored layer 6, and then a sealing process is performed on the alumite layer 5. Yes. For example, when a marking surface that has been subjected to an alumite treatment is masked and subjected to a coloring treatment, the coloring material enters and adheres to the surface of the masking member, the surface of the anodized layer, and the fine holes in the anodized layer. By performing post-treatment such as washing with water, the coloring material attached to the surface of the masking member and the surface of the alumite layer is almost peeled off, and almost no coloring material is left. On the other hand, in the alumite layer that is not masked, the colorant penetrates into fine pores, and therefore this colorant is not easily peeled off.
Actually, as shown in FIG. 3, when the unmasked alumite layer 5 is colored, fine holes 8 (nano-unit holes) are formed in a state of being opened on the surface. The colorant enters the fine holes 8, and the colored layer 6 is formed on the surface of the alumite layer 5 and the fine holes 8. Although the colorant on the surface of the alumite layer 5 is easily peeled off, the colorant that has entered the fine holes 8 is not easily peeled off. In particular, when the fine hole 8 is sealed after the coloring process, the coloring material that has entered the fine hole 8 is difficult to jump out, so that the colored state is maintained for a long period of time and a beautiful colored state is maintained. Moreover, even if the peripheral surface 4 is wiped in order to remove dirt, the colored layer 6 is hardly wiped off, and the durability of the colored layer 6 is enhanced.

Since the sealing surface 3 is subjected to sealing treatment in a masked state, the sealing surface is hardly subjected to sealing treatment in the anodized layer of this marking surface, and the fine holes 8 in units of microns remain open. It has become. A stamp name 7 is engraved on the anodized layer 5. Therefore, when vermilion is attached to the seal 7, vermilion enters the minute holes 8 as shown in FIG. 3. As a result, the vermilion paste at the seal name 7 is good, and the seal name 7 is stamped cleanly. In particular, since the stamp surface 3 is the anodized layer 5, it has an appropriate hardness, so that the stamp name 7 of the stamp surface 3 is not easily lost.

Next, the manufacturing method of this seal stamp is demonstrated based on FIG.
First, a stamp material 2 made of an aluminum alloy having a seal shape is prepared. As step 1, a stamp name such as name, surname, and company name is imprinted on the stamp surface 3 of the stamp material 2. In step 2, preprocessing for anodizing is performed. This pretreatment is, for example, a combination of alkali etching, acidic etching, chemical polishing, and the like, and is the same as the normal pretreatment, and detailed description thereof is omitted. After this pretreatment, as step 3, the entire surface, that is, the marking surface 3 and the peripheral surface 4 are subjected to alumite treatment to provide an alumite layer 5. As alumite treatment conditions, depending on the seal material, the required alumite layer is not formed when the treatment temperature is low, the hardness is lowered and the scratches are likely to be high when the temperature is high, and it is preferable to treat at room temperature, 15 to 30 degreeC is preferable. Further, if the treatment time is too short, a necessary alumite layer is not formed, and if the time is long, the film thickness of the alumite layer to be attached increases, and the corners of the marking face are likely to be lost, so that 15 minutes to 50 minutes, In particular, it is preferably 20 minutes to 40 minutes. When the thickness of the alumite layer is large, corners are likely to be lost, and when it is thin, the alumite layer is insufficient and a layer having an appropriate hardness cannot be obtained. Therefore, the thickness is preferably 3 μ to 25 μ, particularly preferably 5 μ to 20 μ. A state in which the alumite layer 5 of the seal surface 3 is not completely sealed (that is, even if the opening area of the fine holes 8 is reduced by the sealing process, the fine holes 8 are completely sealed). In order to leave it in a state of not being present, the stamp surface 3 is masked as step 4. As the masking method, it is only necessary to be able to prevent the coloring process and sealing process of the marking surface, for example, press against a rubber plate of raw rubber, synthetic rubber, etc., press the coating surface, spray or apply rubber or plastic, This is done by attaching a tape or the like. Note that the same masking may be used for masking that also prevents anodizing. When the stamping surface 3 is masked, the anodized layer 5 on the stamping surface 3 can be maintained in a state where the complete sealing process is not performed as described above, so that the fine holes 8 are kept open. Has been.

In step 5, the entire surface is colored with the marking surface 3 masked. At this time, for the peripheral surface 4, the coloring material of the coloring layer 6 enters the fine holes 8 of the anodized layer 5, and for the marking surface 3, the coloring material is only attached to the masked surface. It becomes. After that, by performing a post-treatment such as washing with water, the coloring material adhering to the masked surface and the coloring material adhering to the outer surface of the anodized layer 5 on the peripheral surface 4 are almost peeled off. On the other hand, the coloring material that has entered the fine holes 8 of the alumite layer 5 remains without being peeled off. In this state, as step 6, the alumite layer 5 is sealed. When the sealing process of the alumite layer 5 is performed, the fine holes 8 are closed. As a result, the colorant that has entered the fine holes 8 of the alumite layer 5 is closed in the fine holes 8, and does not jump out. As a result, clean coloring and vivid coloring of the peripheral surface 4 of the seal 1 can be obtained. In addition, although it is the process which performs the sealing process with respect to the whole surface of the stamping surface 3 and the surrounding surface 4, since the alumite layer 5 of the stamping surface 3 is masked, a sealing process is hardly performed. That is, since the masking is performed, the fine holes 8 of the anodized layer 5 on the marking surface 3 remain as they are, or remain open even if the holes are slightly narrowed. It is not completely sealed and closed. In other words, it is not completely sealed and not completely sealed. That is, the complete sealing treatment is applied to the alumite layer 5 on the peripheral surface 4 that is not masked, and the alumite layer 5 on the masked seal surface 3 is in the state described above. Since it may be misleading to explain that the anodized layer 5 of the seal surface 3 is not sealed, in the present invention, the portion that has been sealed after masking is not completely sealed, or I decided to say that it was hardly sealed. The unmasked alumite layer is basically a sealing process, and most of the fine holes 8 are sealed. This sealing process is a sealing process in a range that can be considered in common sense, This is not to say that all fine holes must be sealed. Thereafter, in step 7, the masking of the stamp surface 3 is removed.
The coloring color may be any color such as gold, silver, red, white, pink, blue, cherry blossom, red and white, and iridescent, and is not particularly limited. The conditions of the coloring treatment are slightly different depending on the color to be colored. However, if the temperature is too low, coloring cannot be performed, and if the temperature is too high, the cost of the processing equipment is increased. 70 ° C. is preferred. The treatment time is preferably 3 seconds to 10 minutes, particularly 7 seconds to 5 minutes, because if the treatment time is short, no beautiful color or vivid color can be obtained, and if the time is too long, the productivity is poor.

As a result, the anodized layer 5 that has been anodized on the stamped portion (name of the mark) remains on the surface that has not been subjected to the coloring process and the sealing process. On the other hand, the peripheral surface 4 is colored after the alumite treatment, and is provided with a colored layer 6 and further sealed, so that a colored layer 6 having excellent adhesion without peeling and showing a vivid color is obtained. It is done. As described above, the colored layer 6 has good adhesion and is not easily peeled off, is difficult to be contaminated, and is easy to wipe.

(Example 2)
Based on FIG. 5, the manufacturing method of the seal stamp by Example 2 is demonstrated. Description of the same part as Example 1 is abbreviate | omitted, and a different process is demonstrated. In the second embodiment, the stamp of the stamp name 3 in step 11 is the same as step 1 in the first embodiment. The stamp masking process in step 12 is the same as step 3 in the first embodiment, and the pretreatment process in step 13 is the same as step 2 in the first embodiment. As described above, the pretreatment process may be performed before or after the stamp face masking. In some cases, some cleaning process is required even before the marking, and in this state, a part of the pretreatment process or all of the pretreatment process may be performed. Step 14 is an alumite treatment process. In this step, since the marking surface 3 is masked, the alumite treatment is not performed, and the portion other than the marking surface 3, that is, the peripheral surface 4 is alumite treated. Thereafter, similarly to Steps 5, 6, and 7 of the first embodiment, coloring processing, sealing processing, and masking removal are performed as Steps 15, 16, and 17, respectively.
In Example 2, the stamping surface 3 is not subjected to an alumite treatment and remains the aluminum alloy base material 2 so that the stamping surface 3 can be easily stamped without increasing the hardness. In particular, the stamp name to be stamped on the stamp surface is simple and suitable for the case where the thickness is thick and the hardness is not so required because it is easy to stamp.

Example 3
Based on FIG. 6, the manufacturing method of the seal stamp by Example 3 is demonstrated. Description of the same part as Example 1 is abbreviate | omitted, and a different process is demonstrated. The third embodiment is greatly different from the first and second embodiments in that the stamp name is not stamped before the anodizing process or coloring process, but is finished as a seal, and the rest is stamped. It was in good condition so that it could be stamped later when needed. The third embodiment is advantageous in that it can produce a large amount of stamps that are not engraved and stock them, and a product with excellent productivity can be obtained.

Specifically, as step 21, a pretreatment process similar to that of step 2 is performed, and as step 22, the entire alumite process similar to that of step 3 is performed. As a step 23, a seal face masking process similar to that of the step 4 is performed, and as a step 24, a coloring process similar to that of the step 5 is performed. Further, as step 25, a sealing process similar to that of step 6 is performed, and as step 26, a masking removal process similar to that of step 7 is performed. In this state, the stamp surface is still anodized, and the peripheral surface is anodized, colored, and further sealed. Next, as a step 27, the stamp name is stamped. It is also possible to stock the seals in the state up to step 26 without stamping the stamp name immediately, and to stamp the stamp name when the stamp name is determined. On the premise that a stamp name is engraved as step 27, the seal stamps that have been kept in the process up to step 26 are also included in the present invention. In the third embodiment, since the steps up to step 26 are performed and a large number of seals in which the seal names are not engraved can be prepared, mass production is possible and the productivity is excellent.

Example 4
Based on FIG. 7, the manufacturing method of the seal stamp by Example 4 is demonstrated. Description of the same part as Example 3 is abbreviate | omitted, and a different process is demonstrated. As in Example 3, the stamping of the stamped name is used as a post-process, and a stamp with no stamped name can be prepared for mass production. Excellent in properties. Further, as in the second embodiment, the stamp face is made of an aluminum alloy material.

More specifically, in step 31, the marking surface is masked so that the marking surface remains as an aluminum alloy material. In step 32, pre-processing of the unmasked peripheral surface is performed, and in step 33, the peripheral surface alumite processing is performed. At this time, since the stamp face is masked, the alumite treatment is not performed. Thereafter, as step 34, the entire periphery is colored. With respect to the alumite layer on the peripheral surface, the colorant is in a state of entering fine pores, and the colored layer enters the alumite layer. On the other hand, with respect to the marking surface, the colorant is only adhered on the masking and is removed together when the masking is removed. Alternatively, there is a high possibility that the coloring material will be peeled off even after the post-coloring treatment, that is, washing with water. Thereafter, as a step 35, the alumite layer is sealed. Thereafter, the masking of the stamp surface is removed. As a result, the stamp surface remains an aluminum alloy material, and a seal material having an alumite treatment, a coloring treatment and a sealing treatment on the peripheral surface is obtained. Thereafter, at an appropriate timing, as a step 37, a stamp name is stamped on the stamp surface. Also in this example, a seal stamp not engraved on the stamp face is also included in the present invention as in the third embodiment.

(Example 5)
Based on FIG. 8, the manufacturing method of the seal stamp by Example 5 is demonstrated. Description of the same part as Example 3 is abbreviate | omitted, and a different process is demonstrated. As in Example 3, the stamping of the seal name is used as a post-process, and a large number of seals without the stamp name can be prepared, enabling mass production. Excellent in productivity.

Specifically, in step 41, pretreatment is performed on the entire surface of the aluminum alloy material, and in step 42, alumite treatment is performed on the entire surface. Thereafter, as step 43, the entire periphery is colored. There is a state in which the coloring material enters the fine holes of the anodized layer, and the colored layer is in close contact with the anodized layer. Next, as a step 44, a sealing process of the alumite layer is performed. As a result, the colorant that has entered the fine pores of the alumite layer is closed, and a material with excellent adhesion of the colored layer is obtained. As a seal material, keep it as it is, and when stamping the seal name and commercializing it, as step 45, remove the alumite layer (sealed) and colored layer on the stamped surface by a method such as shaving. To do. As a result, the aluminum alloy material is exposed, and in step 45, the surface is engraved with a seal name.
In the fifth embodiment, masking and removal work of this masking are unnecessary, and the workability is excellent. In addition, since the entire circumference is colored, a product having excellent visual properties is obtained, and it is difficult to get dirt and has excellent storage stability.

(Example 6)
Based on FIG. 9, the manufacturing method of the seal stamp by Example 6 is demonstrated. Description of the same part as Example 5 is abbreviate | omitted, and a different process is demonstrated. Example 6 is different from Example 5 in Example 5. In Example 5, the alumite layer (and colored layer) on the stamping surface was removed to expose the aluminum alloy material, and the exposed surface was engraved. In No. 6, an alumite process is performed on the stamped stamp surface.

Specifically, in step 51, pretreatment is performed on the entire surface of the aluminum alloy material, and in step 52, alumite treatment is performed on the entire surface. Thereafter, as step 53, the entire periphery is colored. There is a state in which the coloring material enters the fine holes of the anodized layer, and the colored layer is in close contact with the anodized layer. Next, as a step 54, an alumite layer is sealed. As a result, the colorant that has entered the fine pores of the alumite layer is closed, and a material with excellent adhesion of the colored layer is obtained. As a seal material, keep it as it is. At the time of commercialization by engraving the seal name, as step 55, the alumite layer (sealed) and the colored layer on the stamp surface are removed by a method such as shaving. As a result, the aluminum alloy material is exposed, and in step 56, the surface is engraved with a name. Thereafter, in step 57, after the marking, the marking surface is anodized. By this alumite treatment, a hard and excellent wear-resistant material can be obtained, and an imprint that does not change for a long time can be obtained. Less likely to cause imperfections or deformations in imprints. By alumite treatment, the surface area of the stamp surface increases by about 40,000 times before treatment, so that the vermilion is good. Since the marking surface is not anodized, the marking surface is easy to process and easy to process. In addition, when anodizing the stamp surface, it is preferable to mask the alumite layer (colored / sealed alumite layer) around the seal, but it is not always necessary.
In Example 6, since the stamp surface can be stamped on a relatively soft stamp surface made of an aluminum material, it is easy to stamp. In addition, since the stamping surface is anodized after the marking, the stamping surface has high hardness, the durability of the stamping surface is greatly improved, and the surface area is greatly increased, so the vermilion paste is good and a clear imprint can be obtained. .
Further, since the entire surface is subjected to alumite treatment, coloring treatment and sealing treatment without masking, a smooth and clean colored surface can be obtained. In particular, since partial masking is not performed, there is no boundary between the masked portion and the non-masked portion, so it is not necessary to worry about the appearance and processing at the boundary, and the workability is excellent. In addition, since a large number of seals can be prepared in a state in which the seal name is not engraved, mass production is possible and productivity is excellent.

(Example 7)
Based on FIG. 10, the manufacturing method of the seal stamp by Example 7 is demonstrated. Description of the same part as Example 6 is abbreviate | omitted, and a different process is demonstrated. In Example 7, as in Example 6, the aluminum alloy material of the marking surface is exposed. However, the marking surface is not directly engraved as in Example 6, but is engraved after anodizing the marking surface. is there.

Specifically, in step 61, pretreatment is performed on the entire surface of the aluminum alloy material, and in step 62, alumite treatment is performed on the entire surface. Thereafter, as step 63, the entire periphery is colored. There is a state in which the coloring material enters the fine holes of the anodized layer, and the colored layer is in close contact with the anodized layer. Next, as a step 64, an alumite layer is sealed. As a result, the colorant that has entered the fine pores of the alumite layer is closed, and a material with excellent adhesion of the colored layer is obtained. As a seal material, keep it as it is. When the stamp name is engraved and commercialized, in step 65, the alumite layer (sealed) on the stamp surface and the colored layer are removed by a method such as shaving. Thereby, the material made of aluminum alloy is exposed. Thereafter, in step 66, only the stamp surface is anodized again. In step 67, the stamp name is engraved on the alumite-treated stamp surface. In Example 7, since the alumite treatment is performed before the marking surface is engraved, the marking surface has a higher hardness than the hardness of the aluminum material, but burrs are hardly generated when the marking surface is etched. In addition, the alumite treatment can provide a hard and excellent wear-resistant material that does not change the imprint for a long time. Less likely to cause imperfections or deformations in imprints. By alumite treatment, the surface area of the stamp surface increases by about 40,000 times before treatment, so that the vermilion is good.
In Example 7, since the entire surface is subjected to anodizing treatment, coloring treatment, and sealing treatment without masking, a smooth and clean colored surface can be obtained. In particular, since partial masking is not performed, there is no boundary between the masked portion and the non-masked portion, so it is not necessary to worry about the appearance and processing at the boundary, and the workability is excellent. In addition, since a large number of seals can be prepared in a state in which the seal name is not engraved, mass production is possible and productivity is excellent.
In the seventh embodiment, when the stamp name is engraved and commercialized, the stamp face is subjected to the alumite treatment again. However, the alumite treatment may be prepared in advance.

(Example 8)
Based on FIG. 11, the manufacturing method of the seal stamp by Example 8 is demonstrated. Description of the same part as Example 3 is abbreviate | omitted, and a different process is demonstrated. In the eighth embodiment, the third embodiment is further improved. In general, when masking the marking surface after anodizing the entire surface, it is often the case that a masking process is performed on the marking surface while retaining a part of the peripheral surface of the seal. There is a high possibility that the surface of the alumite treatment layer held at that time becomes uneven and a clean surface cannot be obtained. In particular, when coloring treatment is performed, color unevenness occurs and it is difficult to obtain a uniform and vivid colored layer. On the other hand, in the eighth embodiment, this problem is solved.

Specifically, in step 71, pretreatment is performed on the entire surface of the aluminum alloy material, and in step 72, alumite treatment is performed on the entire surface. Thereafter, in step 73, the anodized seal face is masked. After this masking, as a step 74, the surrounding alumite layer is removed by means such as cutting. In step 75, the surrounding surface is preprocessed. In step 76, the pretreated peripheral surface is alumite again. Note that the alumite process in this case may or may not be performed on the masked seal surface, so in step 76, the entire alumite process is performed. Thereafter, as step 77, the alumite layer is colored. There is a state in which the coloring material enters the fine holes of the anodized layer, and the colored layer is in close contact with the anodized layer. Next, as a step 78, the alumite layer is sealed. As a result, the coloring material that has entered the fine pores of the alumite layer is closed, and a colored layer having excellent adhesion can be obtained. As a seal material, keep it as it is. When the stamp name is engraved and commercialized, as a step 79, masking of the stamp face is removed. Thereby, the stamp face having the alumite layer applied in step 72 is exposed. Thereafter, in step 80, the stamp name is stamped on the anodized seal.
In Example 8, an alumite-treated layer that has not been sealed is obtained as the marking surface, so that a hard and excellent wear-resistant layer can be obtained, and a marking that does not change for a long time can be obtained. Less likely to cause imperfections or deformations in imprints. By alumite treatment, the surface area of the stamp surface increases by about 40,000 times before treatment, so that the vermilion is good. In addition, since the anodized layer applied before masking the stamped surface is once removed and the stamped surface is masked again, the peripheral surface of the seal stamp is subjected to anodizing again, so that a clean surface is obtained. In particular,
Since the coloring treatment and sealing treatment are performed after the anodizing treatment, a smooth and clean colored surface can be obtained. In particular, there is no color unevenness and a uniformly vivid colored surface can be obtained. In Example 8, when the stamp name is engraved and commercialized, the masking of the stamp surface is removed and the stamp surface is stamped, and a large number of seals without the stamp name stamped are used. Therefore, mass production is possible and the productivity is excellent. Further, since the marking surface is masked, it is excellent in terms of protection of the marking surface.

Example 9
Based on FIG. 12, the manufacturing method of the seal stamp by Example 9 is demonstrated. Description of the same part as Example 8 is abbreviate | omitted, and a different process is demonstrated. In the eighth embodiment, the marking surface is stamped in the last step, but the ninth embodiment is different from the eighth embodiment in that the stamping is performed at an early stage.

Specifically, in step 81, the entire surface of the aluminum alloy material is pretreated, and in step 82, the entire surface is anodized. In step 83, a stamp name is imprinted on the stamped surface. Thereafter, in step 84, the stamped seal face is masked. After this masking, as a step 85, the surrounding alumite layer is removed by means such as cutting. In step 86, the surrounding surface is pretreated. Further, as step 87, the pretreated peripheral surface is alumite treated again. Note that the alumite treatment in this case may or may not be performed on the masked seal face, and therefore, in step 87, the entire alumite treatment is performed. Thereafter, as step 88, the alumite layer is colored. There is a state in which the coloring material enters the fine holes of the anodized layer, and the colored layer is in close contact with the anodized layer. Next, as step 89, the alumite layer is sealed. As a result, the colorant that has entered the fine pores of the alumite layer is closed, and a material with excellent adhesion of the colored layer is obtained. In step 90, masking of the stamp face is removed.
In Example 9, since the alumite-treated layer that has not been sealed is obtained as the marking surface, a hard and excellent wear-resistant layer can be obtained, and the imprinting that does not change for a long time can be obtained. Less likely to cause imperfections or deformations in imprints. By alumite treatment, the surface area of the stamp surface increases by about 40,000 times before treatment, so that the vermilion is good. In addition, since the anodized layer applied before masking the stamped surface is once removed and the stamped surface is masked again, the peripheral surface of the seal stamp is subjected to anodizing again, so that a clean surface is obtained. In particular,
Since the coloring treatment and sealing treatment are performed after the anodizing treatment, a smooth and clean colored surface can be obtained. In particular, a uniform and vivid colored surface can be obtained without color unevenness. Further, since the stamped surface is masked, it is excellent in terms of protecting the stamped surface.

In the present invention, the description has been made on the assumption that the stamp name is finally engraved on the stamp surface, but even the seal material before the stamp name is engraved is a spare stamp material, and such a spare stamp material is also a book. It shall be included in the invention.

  The seals of the present invention are applicable to all seals such as personal seals, bank seals, real seals, company seals / representatives seals, group seals, trade names, trade marks, mark marks, commemorative marks, design marks, design marks, etc. it can.
