Related to a method for manufacturing a structure that is particularly suitable for molded automotive interior parts (prior technology) Conventionally, many automotive interior molded parts such as door trims and quarter trims are made of skin material by methods such as vacuum forming and press molding. is being pasted. Incidentally, in the case of vacuum forming, as shown in Fig. 3, the skin material 1 is heated to a high temperature.
0 is sucked through the base material 12 and the mold 15 by vacuum pressure V, and is molded into the shape of the base material 12 to form the molded skin material 10.
a and the base material 12 are bonded together with an adhesive. The powder slush method is also known as a method for producing skin materials free of residual stress. In this method, as shown in FIG. 4, the mold 11 is generally a concave shape with a texture and is heated to a high temperature, and when the tank body 14 is reversed (in the R direction), the vinyl chloride resin powder 15 is poured into the mold. 11 to form a skin material.
