    • a method for producing a plastic product having a grained surface is disclosed. The method includes heating a sheet shaped laminate material made of a thermoplastic resin to a predetermined temperature, placing the heated laminated material between a male die and a female die. The female die has a grain pattern on an inner surface thereof and a plurality of minute holes therethrough. The method further includes closing the male die and the female die such that the heated laminate material is pressed against the inner surface of the female die by the male die, drawing the laminate material to the female die by a vacuum through the plurality of minute holes of the female die so that the grain pattern on the inner surface of the female die is transferred to the laminate material, injecting thermoplastic molten plastic material to a space between the laminate material and the male die, and cooling the injected thermoplastic molten plastic material so that the plastic product having a predetermined shape is formed between the male die and female die and the laminate material having the grain pattern is integrally laminated on the plastic product.
    • 公开了一种用于生产具有颗粒表面的塑料制品的方法。 该方法包括将由热塑性树脂制成的片状叠层材料加热到预定温度,将加热的层压材料放置在阳模和阴模之间。 阴模在其内表面上具有颗粒图案,并且穿过其中的多个微孔。 该方法还包括关闭阳模和阴模,使得加热的层压材料通过阳模压靠在阴模的内表面上,通过多个微孔通过真空将层压材料拉到阴模 的阴模,使得阴模内表面上的纹理图案被转印到层压材料上,将热塑性熔融塑料材料注射到层压材料和阳模之间的空间中,并将注入的热塑性塑料材料冷却 在阳模和阴模之间形成具有预定形状的塑料制品,并且将具有颗粒图案的层压材料整体层压在塑料制品上。
