Description

[Detailed description of the invention] The present invention relates to method 1 for manufacturing door materials.

Conventional door materials can be roughly divided into wooden doors, gold 1IIIllV
A. Wooden doors are different from plastic doors because of the texture of the wood.

There are warps and cracks due to the use of wood 1 *
Manufacturing 1: Cutting 1 Surface finishing, drilling.

Various processes such as gluing, generation of wood powder and dust, volatilization of solvents in the adhesive used, long-term curing vII
However, there are some disadvantages such as difficulty in obtaining good quality wood and obtaining homogeneous material, which is a common problem when using wood for TR.

Metal doors have the advantage of being strong and fire-resistant, but generally speaking, there is a tendency for them to be installed one on top of the other, resulting in restrictions on the parts where they can be used, and the need for large presses and metal tJ! v echoes,
Father, to use metal 1.

Combining it with Koshukai I11 parts and leaving the cutting surface unattended is not preferable in terms of rust prevention, and the use of this product is limited.

Plastic doors are generally lightweight and 11i11
Each process has advantages such as being able to use existing equipment and making it easy to obtain homogeneous materials, and it is also easy to impart various properties by selecting materials, making it ideal for interior doors. Its usage has been increasing in recent years.

However, plastic doors are fixed to plastic plates by vacuum forming or compression molding using a desired adhesive or screws, and if the adhesive application process is involved, the process is complicated, and the adhesive There are problems such as the need to increase the ring spacing t1 for the solvent in the adhesive to dry, and the length of time required to leave the adhesive bonded while being crimped. There is also fusion.

The present invention provides 11iI of the above-mentioned conventional door material! One object of the present invention is to eliminate the drawbacks in the method. and a connecting plate part perpendicular to the downward slope part.
Cut the V-cut into a V-cut S shape, bend the V-cut to form a frame V, adhere door surface material to the front and back surfaces of the frame, and then apply edge cover material along the outer circumferential surface. It is moldy to stick to v#.

A detailed explanation of the II configuration of the present invention will be given below.
