In the manufacturing process of FIG. 1, reference numeral S1 denotes a process of preparing a synthetic resin plate and a leather fabric, and reference numeral S2 denotes a process of attaching a synthetic resin plate and a leather fabric.

The preparation step (S1) is to prepare a rectangular synthetic resin plate (T1) and a square leather fabric (T2) having a size corresponding to the tray (T), respectively, as shown in FIG.

The synthetic resin plate (T1) can be used in a common acrylic plate or polycarbonate plate, the leather fabric (T2) can be used in natural leather or synthetic leather (leather).

In particular, the leather fabric (T2) may be made of natural leather or synthetic leather having predetermined decorative patterns on one surface thereof in an uneven form and excellent in texture and touch.

Then, when the synthetic resin plate (T1) and leather fabric (T2) is prepared as described above, the step (S2) of adhering them is carried out.

That is, as shown in Figure 3 to form an adhesive layer (T3) with a liquid adhesive on one surface of the synthetic resin plate (T1).

Although not shown in the drawings, the adhesive layer T3 may be formed on one surface of the synthetic resin plate T1 while being coated or sprayed by a conventional method.

The liquid adhesive uses a conventional acrylic adhesive containing acryl in a solvent and widely used for general purpose plastic bonding. In particular, since the acrylic adhesive is known to be transparent and excellent in shear strength and peel strength, it is possible to increase the adhesion between the synthetic resin plate (T1) and the leather fabric (T2).

Then, when the leather fabric T2 is attached to the synthetic resin plate T1 with the adhesive layer T3 interposed therebetween, the leather fabric T2 is attached to the synthetic resin plate T1 by the adhesive force of the adhesive layer T3. Attached in a state covering one side.

When the attachment operation is completed as described above, the heat treatment step (S3) proceeds.

This heat treatment operation is put into the internal space (D1) of the heat treatment apparatus (D) as shown in Figure 4 in the state that the synthetic resin plate (T1) and the leather fabric (T2) is attached to each other and heat treated at a predetermined temperature.

The heat treatment apparatus (D) may use a conventional heat treatment oven or chamber, and the synthetic resin plate (T1) and the leather fabric (T2) in the inner space (D1) in the range of about 130 degrees Celsius to 160 degrees Celsius It is operated for heat treatment.

As such, when the heat treatment is performed, the adhesive layer T3 between the synthetic resin plate T1 and the leather fabric T2 may be stabilized, and in particular, ductility may be imparted to the synthetic resin plate T1.

It becomes ductile by heat.

When the synthetic resin plate (T1) has a ductility, for example, it can be easily bent in the direction in which the external force acts, so that the molding operation can be carried out simply by a press method in the molding process (S4) described later.

And, when the heat treatment operation is lower than the above heat treatment temperature, since the ductility is not appropriately imparted to the side of the synthetic resin (T1) can not proceed smoothly to the press molding operation, if higher than the above heat treatment temperature, the leather The far end T2 may be burned or deformed (contracted) by heat.

The heat treatment device (D) may be connected to the vacuum generating device (D2) as shown in FIG. This vacuum generator (D2) is for forming the internal space (D1) of the heat treatment device (D) in a vacuum atmosphere can be used a conventional vacuum pump.

That is, the vacuum generator (D2) is operated to form the internal space (D1) in a vacuum atmosphere when the heat treatment operation in the heat treatment device (D).

As such, when the heat treatment is performed in a vacuum atmosphere, bubbles of the adhesive layer T3 formed between the synthetic resin plate T1 and the leather fabric T2 can be removed, so that the synthetic resin board T1 and the leather fabric T2 are removed. It can be attached more uniformly while increasing the adhesive strength of.

After the heat treatment is completed as described above, the molding process (S4) is performed. This molding operation proceeds with a conventional press molding method using a press molding machine P as shown in FIG.

In the press molding machine P, as shown in FIG. 5, a molding mold P1 having a molding space Q is disposed on a work surface, and the press molding machine P is driven on the molding mold P1. It has a structure in which the pressing mold P2 fixed to be movable up / down is disposed.

That is, the synthetic resin plate (T1) and the leather fabric (T2), which is softened by heat treatment, is pressed on the pressing mold (P2) as shown in FIG.

Then, the synthetic resin plate (T1) and the leather fabric (T2) is pressed into a shape corresponding to the molding space space (Q) of the molding mold (P1) is molded to have a tray (T) shape as shown in FIG. .

Thus, the tray T can be made integrally formed with the leather layer by the leather fabric (T2) through the above working processes.

In particular, when the leather fabric (T2) is attached to one side of the tray (T), it is possible to give a unique surface texture and feel of natural leather or synthetic leather can further improve the product quality (advanced) of the product. .

Tray manufacturing method according to an embodiment of the present invention, may be made further comprising a finishing step (S5).

The finishing process (S5) is for surface treatment of the edge portion of the tray (T) molded in a predetermined form in the molding process (S4).

That is, as shown in Figure 7, for example, using a separate grinder (G, or knife) may be finished by grinding the edge of the synthetic resin plate (T1) and the leather fabric (T2) of the tray (T).

In this way, you can easily remove various foreign objects, irregular projections or grooves on the molded tray (T) border.
