Description

Furniture manufacturing method {FURNITURE MANUFACTURING METHOD}

The present invention relates to a furniture manufacturing method, and more particularly, to a furniture manufacturing method implemented to manufacture various types of furniture that maintains high gloss for a long time even after the manufacturing is completed.

In general, various furniture and building interior materials are manufactured through processes such as cutting-processing-polishing-painting.

In particular, in various furniture products and interior materials, a decorative pattern is formed on the front part or in an arbitrary location required for the purpose of beautifully decorating the exterior of the furniture. As a means of carving various patterns by hand, a method of forming a pattern part by separately manufacturing and attaching a decorative pattern plate or painting a wooden surface is common.

However, in the former case, the wood used as a decorative pattern is a high-priced wood imported from a foreign country, and the wood is naturally dried over a year and then dried again in a drying room for about 1 month, and thus dried. Solid wood is manufactured through a process in which various types of patterns are engraved in the engraving process, and then various paints are applied to express the color if necessary. As a lot of manpower and time are consumed, the manufacturing process is cumbersome and productivity is reduced. In addition to the decline, mass production is not possible, and the cost increases.

Painting according to the prior art usually consists of a process of applying a paint to a wooden surface and then drying, more specifically, a process of undercoat (polishing the wooden surface)-medium-top coat.

However, the conventional coating method is a simple technique in which the paint is applied over several layers (undercoat-middle layer-upper coat), so the texture of wood does not appear naturally, so the texture of wood is clogged or the surface is not clear. There is this.

On the other hand, the above-described background technology is technical information that the inventor possessed for derivation of the present invention or acquired during the derivation process of the present invention, and is not necessarily a known technology disclosed to the general public prior to filing the present invention. .
