    • A surfacing material (41) such as a sheet of raised fabric or a foamed cushion sheet is disposed in advance inside a mold (20), and a molten resin (30) is then packed into this mold (20) to mold a molded article having a layer of the surfacing material (41) and a layer of the resin (30) laminated with each other. In this case, a compressive force necessary for fluidization is applied to the mold (20) until the molten resin (30) completely fills the inside of the mold (20), and after the molten resin (30) is fully packed, the compressive force applied to the mold (20) is decreased. The decreasing of compression helps to prevent the nap on a raised fabric sheet from falling and also prevent a thick fabric or cushion sheet from becoming thinner under excessive pressure. Accordingly, excellent moldability can be imparted to the molded article, and even after molding is completed, the properties of the surfacing material (41) can be maintained as such.
    • 预先在模具(20)内设置诸如起绒织物片或泡沫垫片的表面材料(41),然后将熔融树脂(30)包装到该模具(20)中以模制成型品 具有堆叠材料层(41)和层叠的树脂层(30)。 在这种情况下,将流化所需的压缩力施加到模具(20),直到熔融树脂(30)完全填充到模具(20)的内部,并且在熔融树脂(30)被完全包装之后,压缩 施加到模具(20)的力减小。 压缩的减少有助于防止起绒织物片上的绒毛掉落,并且还防止厚的织物或缓冲片在过大的压力下变薄。 因此,能够赋予成型品优异的成型性,即使在成形后也能够保持表面材料(41)的特性。
