Hereinafter, an embodiment of a method for manufacturing a non-glossy emblem of the present invention and a non-glossy emblem manufactured through the method will be described.

First, in FIG. 1, the appearance of plating the electric slab 200 on the master 110 through the electroforming method is shown.

The electroforming method TECHNICAL FIELD It relates to the electroforming method for shaping|molding a metal product.

Electroforming technology (electroforming method) is known as a method for manufacturing fine metal products that are difficult to manufacture by machining. This is an electroplating process in which a metal is thickly plated against a model, and then the thick film plating (metal molded article) is peeled off from the model to form a metal product, which is generally thicker than 20 µm. The thickness of the electroplating is called an electric pole (hereinafter referred to as the electric pole 200 below).

2 to 7, the emblem electroforming method according to a preferred embodiment of the present invention is CNC-processed to first produce a mold (hereinafter, the master 110) in which the emblem shape is formed on the intaglio (S01).

Then, the plating material is plated in a laminated form through the manufactured master 110 and peeled off to produce the electric pole 200 .

To this end, the master 110 is manufactured and the error of the intaglio plating surface 120 is compared with the design value and reprocessed, while the corners or dimension parts of the emblem are corrected as a whole, and the final shape of the master 110 is determined. will catch

Subsequently, according to an embodiment of the present invention, the surface of the master 110 may be processed to form an intaglio on the emblem (S02).

The first master 110 has an engraved plating surface 120 according to the shape of the emblem, and among them, an embossed area and an engraved area are divided in the emblem, and a surface treatment is performed on the intaglio area.

The surface treatment method used in the present invention is sand blaster (SAND BLAST), and it can be etched by spraying sand on the surface of the plating surface 120 by blowing sand vigorously.

Through this, the surface of the intaglio region has a roughness and the intaglio region remains even after the plating material is plated.

Subsequently, before plating on the plating surface 120 of the master 110 , an anode electrolysis and release treatment are performed.

The anodic electrolysis is a process for increasing adhesion when the plating material is plated, and the release treatment is a process for facilitating the removal of the electroform 200 after anodizing.

In the anode electrolysis, oxygen gas is generated in the product during electrolysis by using the intaglio of the master 110 as an anode, and the surface of the plating surface 120 is oxidized to form a passivation film.

And when this oxide film is activated and peeled off before plating, fine etching is made on the surface to improve adhesion.

And when a release agent is applied to the plating surface 120 on which the oxide film is formed and then the plating material is plated and then the electric pole 200 is separated from the master 110, the electric pole 200 is distorted, agglomerated or damaged it can be prevented

Meanwhile, the first material 220 , the second material 240 , and the third material 260 are plated on the plating surface 120 on which the anodic electrolysis and release treatment have been completed.

First, the first material 220 and the second material 240 may be plated.

Here, the first material 220 may be bright nickel 220 (Brightenss Nickel), wherein the second material 240 may be semi-bright nickel 240 (Semi-Bright Nickel), and the third material 260 may be MP Nickel 260 (Micro Porous Nickel).

A first material 220 is plated on the master 110 , a second material 240 is plated thereon, and a base nickel 250 is plated on the second material 240 .

The first material 220 , the second material 240 , and the base nickel 250 are plated in a stacked form.

When the plating is completed in this way, the first material 220 , the second material 240 , and the electric pole 200 plated with the base nickel 250 are separated from the master 110 ( S06 ).

Thereafter, a third material 260 and chromium 270 are laminated on the front slab 200 .

After forming the electroforming layer on the master 110, it is a view showing a state in which the electroforming piece 200 is generated by peeling it.

It is possible to manufacture a specific shape by repeating the processing for the peeled former slab 200.

Next, the third material 260 is plated, and thereafter, chrome 270 is additionally plated to complete the glossy emblem.

11 is a diagram illustrating a state in which electroforming plating is performed to form a plating layer.

When plating is completed, the final emblem is completed by washing the electroforming solution or plating solution remaining on the surface and press-working the extended part other than the engraved shape to perform post-processing (S07).

12 shows the final emblem.

In the present invention, electric poles are limited to emblems, but the same method can be used for mobile phones, interior/exterior decorations of home appliances, logo badges, and the like.

Here, in casting nickel, the master 110 is immersed in an electroforming solution and electroforming is performed. Electroforming is performed by using stainless steel as a negative plate and nickel as a positive plate, respectively. Even if the thickness of the electroforming layer is gradually increased, it is possible to prevent a decrease in the component of nickel in the composition of the electroforming solution.

That is, by using stainless steel and nickel for the negative electrode plate and the positive electrode plate, even if the electroforming layer forming step continues, the composition of the electroforming solution can be kept constant, thereby uniformly maintaining the properties such as the crystal structure of the electroforming layer. there will be In addition, the electroforming layer formation can be more activated while maintaining a uniform distribution of components in the electroforming solution by continuously stirring the electroforming solution while the electroforming layer forming step is in progress.

Here, the electric pole layer refers to the plating layer of the electric pole piece 200 .

On the other hand, a plating layer is formed after the pole 200 is formed. In this embodiment, the conditions for plating the first material 220 are 240 to 320 g/l of nickel sulfate, 40 to 60 g/l of nickel chloride, and 35 to 45 g of boric acid. The first material 220 and the second material 240 are respectively plated on the plating surface 120 of the intaglio 52 of the electric slab 200 in an electroforming solution using /l as a main material.

As described above, the first material 220 may be bright nickel 220 , and the second material 240 may be semi-gloss nickel 240 .

To prepare the dry bath, about 60% of water is added to the bath 10, and the temperature is about 50° C., the nickel sulfate, boric acid, and nickel hydrochloride are added and stirred to dissolve. When the pH (acidity) is low during stirring, nickel carbonate is added, and activated carbon is additionally stirred for 3 to 5 hours to prepare.

In addition to the above main material, the first material 220 is plated by adding 0.5 to 1.2 ml/l of a first varnish, 10 to 15 ml/l of a second varnish, 1-3 ml of a third glaze, and 1-2 ml of a wetting agent as auxiliary materials. will do

At this time, the conditions of the electroplating are to form the first plating layer 134 of 7.5 ~ 7.8㎛ under the condition of a ^{current of 1 ~ 6 A / dm 2} for 15 ~ 25 minutes at 50 ~ 65 ℃ ℃.

Plating the first material 220 on the electric slab 200 facilitates the correction of the plating film potential and improves the corrosion resistance through the appearance and leveling of the plating layer.

The second material 240 is plated on the first material 220, and the dry bath preparation of the second material 240 is 280-300 g/l of nickel sulfate, 30-35 g/l of nickel chloride, and 35 of boric acid in the bath 10. Prepare a dry bath using ~40g/l as the main material, and 0~1ml/l of the 6th polish, 1-2ml/l of the 7th polish, and 1~3ml/l of the wetting agent as auxiliary materials.

The plating condition of the second material 240 is to obtain a plating layer of 13.1 to 13.7 μm under the condition of a current of 0.5 to 5 A/dm2 for 13 to 23 minutes at 50 to 60° C., and then the base nickel 250 is plated. .

If the second material 240 is continuously laminated, there is an effect that a plating layer having excellent physical properties and low hardness can be obtained.

On the other hand, the third material 260 to be plated on the second material 240 is the fourth varnish 2 to 6 ml/l, the fifth varnish 5 to 15 ml/l, the 1 MP powder 0.5 to 1 g/l, and the 2 MP powder 0.02 to 0.2 g/l, a small amount of 3MP powder is used as an auxiliary material.

When the third material 260 is plated, the corrosion resistance of the film itself is improved, the progress of corrosion is further alleviated, and the change in the number of micropores due to the pH fluctuation of the bath or the increase in the thickness of the chromium 270 plating film is alleviated. It has the effect that the management of unaired water also becomes easy.

In addition, uniform micropore water can be obtained, the surface glossiness is excellent, and the amount of solid fine particles added is small, so the filterability is excellent. Due to this, there is an advantage in that the hassle required for purification of the plating solution is greatly reduced.

After the third material 260 is plated according to a preferred embodiment of the present invention, trivalent chromium 270 is plated.

The trivalent chromium 270 is plated on one surface of the third material 260. When a plating layer of 13.1 to 13.7 μm is obtained under the condition of a current of 0.5 to 5 A/dm2 for 13 to 23 minutes at 50 to 60 degrees Celsius, plating is performed. As a condition, it becomes 0.44~0.5㎛ under the condition of 2 minutes at a current of 9.2 A/dm2.

When the trivalent chromium 270 is plated on the third material 260 as above, countless pores are generated in the trivalent chromium 270 plating layer 138 and the corrosion current is dispersed on the film, thereby reducing the corrosion rate of plating, It has the advantage of smoothing the surface of the product.

And the finished pole 200 is washed. First, the pole slab 200 is pickled and washed for 5-10 minutes at 50-55 ° C., and then electrolytically degreased under the condition of 50-55 ° C with a voltage of 4-7 V. carry out

Then, pickling is carried out for 15 to 30 seconds to remove the oxide film on the surface of the former slab 200 .

The emblem produced by this electroforming method separates the previously plated electric slab 200 from the master 110 after the first material 220, the second material 240, and the base nickel 250 are plated, , and then the third material 260 is provided in a laminated form, and the order in which they are laminated is that the glossy nickel 220 forms a plating layer on the electric pole 200 , and semi-gloss nickel 240 on the plating layer of the glossy nickel 220 . ) forms a plating layer, a plating layer of the base nickel 250 is formed on the plating layer of the semi-gloss nickel 240 , and after the electric pole 200 is separated from the master 110 , the MP nickel 260 is plated and the plating layer is formed, and trivalent chromium 270 is plated on it, and a plurality of layers are laminated thereon, so that the plating layer is 20-50 μm, and finally an emblem of 200 to 250 μm can be completed.

On the other hand, as described above, the emblem manufactured by the present invention has been described above that it has excellent corrosion resistance compared to the conventional emblem.

In addition, since the plating material is directly plated by processing the master 110 , the gloss is excellent, and thus the division between the glossy area 122 and the non-glossy area 124 becomes clear.

Figures 10 and 11 show the degree of corrosion of the completed emblem through the corrosion environment (snow salt test).

10 is a view showing the corrosion size of the plating layer through the corrosion test of the emblem plated with chromium 270 on the electric slab 200 as a prior art, and FIG. 11 is a corrosion test of the emblem manufactured by the manufacturing method according to the present invention. It is a diagram showing the size of corrosion of the plating layer.

10 and 11, in the case of the emblem produced by electroforming in the prior art, chrome 270 is plated on the electric pole 200, and the emblem of this embodiment is a first material 220 on the electric pole 200, After the second material 240 and the third material 260 are plated, the trivalent chromium 270 is plated.

Referring to the drawings, in the case of the emblem manufactured in the prior art, as a result of the corrosion test, the size of corrosion on the surface of the emblem was observed to be 285 μm and 478 μm, respectively, and it was judged to be rejected.

Relatively, it was observed that the size of the corrosion of the emblem prepared by the present invention was 25㎛ and 46㎛, respectively.

As described above, it was confirmed that the plating layers of the first material 220 , the second material 240 , and the third material 260 greatly suppressed corrosion of the surface of the chrome 270 .
