厚くなっている。A laminated molding material to which the present invention is applied in order to solve the above problems will be explained with reference to FIG. 1 corresponding to an example. As shown in the figure, the laminated molding material 1 is composed of a facing material sheet 2, a foamable plastic sheet 3, and a needle-punched nonwoven fabric sheet 4 laminated in this order.The foamable plastic sheet 3 has an expansion ratio of 10. It is ~50 times thicker than both the facing material sheet 2 and the needle punched nonwoven fabric sheet 4.

わっただけで変形してしまう。As can be seen from the table, the thickness of the laminated molding material 1 decreases during molding, and the quality of the finish of the facing material 2 changes depending on the degree of this thickness decrease. The thickness decrease occurs due to compression of the foamable plastic sheet 3 and the nonwoven fabric sheet 4, but since the foamable plastic sheet 3 is in contact with the facing material sheet 2, the thickness reduction mainly occurs due to the thickness reduction of the foamable plastic sheet 3. The thickness reduction affects the surface finish.The thickness reduction of the foamable plastic sheet 3 increases as the expansion ratio increases, and decreases as the expansion ratio decreases. It becomes soft and deforms even when a slight external force is applied to it.

する物を充分に保護できるという利点がある。As explained above, if the laminated molding material to which the present invention is applied is used, when manufacturing cases, there is no need for a step of bonding the facing material and the inner lining, and the case can be integrally molded. This simplifies manufacturing and allows mass production at low cost. Additionally, there is no wrinkles, sagging, or twitching that can occur when bonding facing materials together, resulting in a beautiful finish. The resulting molded product is lightweight, maintains a soft texture in both the outer layer and the inner layer, and has good shape retention and does not lose its shape, so it has the advantage of being able to adequately protect items stored inside.
