Description

Furnishing a door of manufacture method

The present invention relates to a method of manufacturing a door that can be used as a fresh door as well as doors of furniture cabinets, cabinets or built-in cabinets and kitchen furniture (sink stand) by making corresponding sizes and thicknesses according to various use objects. In particular, with medium density fiberboard (MDF) and thermal transfer film paper, it is possible to easily and simply express and produce various patterns of natural wood and various patterns of natural wood, and it is easy to produce and produce products. For furniture that can satisfy various needs of customers and secure high quality of products by increasing the durability, soundproofing and appearance, as well as reducing the incidence of defects and manufacturing cost due to improved workability, etc. It is related with the manufacturing method of a door.

In general, the door of the furniture or building is a substrate (1) tube processed and cut using natural wood, as shown in Figure 7a to 7c, fastening grooves (3a, 4a) of a predetermined depth along the longitudinal direction on one side A plurality of horizontal and vertical members 3 and 4 each of which is formed are fitted to each other at edge edges of the substrate 1, respectively, and both ends of the horizontal and vertical members 3 and 4 correspond to each other to be fitted to each other. Combined and assembled.

However, this door not only has to be assembled by combining the frame 2 into a plurality of horizontal and vertical members 3 and 4, but also the side ends of the substrate 1 in the horizontal and vertical members 3 and 4 are grooved. Subsequently, the coupling grooves 3a and 4a for mutual coupling and substrate coupling are formed in the horizontal and vertical members 3 and 4 of the frame 2 due to the custom coupling structure fitted and assembled to the 3a and 4a. As it requires processing and assembly, it is also required to be elaborate for a long time, so it is assembled and manufactured by skilled workers for a long time. .

If the door manufactured using natural wood is not precisely processed and assembled, a coupling gap caused by the tolerance between the horizontal and vertical members 3 and 4 of the substrate 1 and the frame 2 is generated and used. As the gap becomes larger, it is not only aesthetically unfavorable, but also the defects in which the overall noise, the reliability of the product, and the beauty of the product are deteriorated due to deterioration of the external noise blocking effect due to the gap generated structurally.

Therefore, MDF (Medium Density Fiber Board), which has been artificially improved and manufactured from natural wood for a long time, is used to make it easy to manufacture in various ways, low price, mass production, and feel similar texture like natural wood. I'm doing it.

Such a medium density fiberboard material (MDF) is a compressed wood that is formed by compressing a certain amount of sawdust into a plate shape of a predetermined form through a separately manufactured mold and manufactured without any pattern on the surface, and this medium density fiberboard material (MDF) Unlike other wood such as natural wood, it is formed by compressing sawdust, etc., so it can be produced in various shapes depending on the mold, but there is no unique wood grain pattern like natural wood on its surface. After completion, the appearance is insignificant. Therefore, it is usually produced through the secondary molding process by pressing and coating the transfer paper of the thin synthetic resin material printed with various patterns and shapes such as natural wood grain or marble on the surface of the MDF.

As described above, the film coated on the MDF compressed wood is formed of a printing layer on a transfer film made of polyester resin or polyvinyl resin, and an appropriate amount of adhesive is applied to the outer surface of the MDF compressed wood. The film was directly attached to the transfer film, and then heat-compressed using a separate press device for coating.

However, the conventional transfer film paper is relatively hard before being heated, so that the print layer and the resin layer are not separated, so that if the surface of the processed wood has an embossed surface or a curved surface, cracking occurs in the process of coating the transfer film paper. It is difficult to produce, such as not being adhered to or adhered to, so it is usually avoided for use on curved surfaces, and it takes considerable time to cover the pattern of MDF, including the time required for transferring the transfer film paper on the curved surface or embossed surface. The work was very cumbersome.

Therefore, in order to improve the conventional method for manufacturing a door, the "door manufacturing method" of Patent No. 0253764, which is registered and applied in Korea, is briefly described with reference to the accompanying drawings with reference to FIGS. 8A to 8C.

First, after cutting the substrate 12 corresponding to the overall size of the door, and then the surface processing and polishing to have a contour of the shape and shape to meet the required design; Cutting the disc member into a required shape so that the substrate 12 can be exposed, and then processing the surface to have a contour of the door frame to form a frame portion 20 of a single body; An operation step of attaching the frame portion 20 of the single body to the upper and lower surfaces of the substrate 12 to be integrally bonded to each other; And a manufacturing step of the step of transferring the transfer papers with transfer papers 18a and 18b having a pattern to be produced on the surface of the door to which the frame part 20 is bonded to both sides of the substrate 12 in order to limit the method of manufacturing the door. There is a bar.

However, the conventional method of manufacturing a door

First, since the center portion is removed to expose the substrate 12 to form the frame portion 20 of the single body to have the outline of the door, a large amount of material is unnecessarily wasted, and cutting and precision grinding operations are unnecessary. It is cumbersome and inconvenient, lowers workability and productivity, and high defect rate of the product, which increases the overall manufacturing cost.

Second, in order to perform the transfer treatment process, after applying the adhesive on the surface to be bonded, and then transfer film to the corresponding position by using a separate press device by pressing the heat treatment by coating and fabrication to integrate, if the frame portion 20 When the film is thick, the transfer film does not adhere to the film, or even if it is attached, it is often ruptured at the bent portion, so that the thickness of the frame portion 20 should be considered in a limited state based on the surface of the substrate 12. Although it is difficult to produce, it does not satisfy the needs of various customers, and it uses transfer film paper to produce natural wood patterns, but the user can easily distinguish it with the naked eye, and there is a defect that cannot achieve high-quality products due to low transfer efficiency.

Third, there were problems such as overall productability, reliability, and safety of the product due to factors such as harmfulness and environment of the human body due to the adhesive containing a large amount of harmful substances according to the use of the adhesive more than necessary.

Therefore, the present invention has been made to solve the fundamental problems of the prior art, the purpose of the medium density fiberboard (MDF) and the thermal transfer film paper with a variety of patterns and textures of natural wood or easy to produce It can be simply expressed and produced, and it is easy to produce, reducing the incidence of defects and manufacturing cost due to the improvement of product productivity and workability, as well as increasing durability, sound insulation and appearance, etc. The present invention provides a method of manufacturing furniture doors that meets the various needs of the company and secures high quality products.

In order to achieve the above object, the present invention has a medium density fiberboard material (MDF) of a predetermined width and thickness, and designed in any shape after cutting and cutting the basic surface through a smooth and flat sanding (sanding) the entire outer surface And a first process of manufacturing a set of horizontal / vertical border plates and a central decorative plate, respectively; After a certain amount of adhesive is applied to the front edge edge surface of the base plate, the set of horizontal / vertical edge plates are respectively placed at the corresponding positions so that the receiving groove is naturally provided in the center of the frame and the decorative or base plate along the adhesive coated surface. A second step of firmly attaching and fixing the mat in a protruding state; The entire outer edge of the base plate along with the front and both sides of the one set of horizontal / vertical edge plates were covered with a variety of patterns or patterns of thermal transfer film, and then heated and compressed for a predetermined time in a state of being closely adhered thereto.
