发明名称 METHOD AND DEVICE FOR INJECTION MOLDING
摘要 The present invention contemplates an apparatus and method for molding an article that has a film bonded to a body portion of the finished article wherein the film is transported from a supply roll to a take-up roll so that the film covers the female mold cavity and the adjoining area of the female mold that is the non-molding area or portion of the female molding portion. The film is pre-heated to permit preforming of the sheet to the contour of the female mold cavity. As the female mold and the male mold are brought into abutting contact, the film is most preferably retained between certain portions of the mold to allow the movement of the film inwardly towards the mold cavity as thermoplastic material is injected into the mold cavity for bonding with the film as the article is formed in the mold cavity.
