METHODS AND APPARATUSES FOR INJECTION MOLDING WALLED STRUCTURES |
摘要 |
A process is provided for making a walled structure using an injection molding apparatus. The apparatus has a molding space formed between a mold cavity and an inner core disposed within the mold cavity. The molding space defines a shape of the structure. The process includes injecting molding material into the molding space, moving or retaining a portion of a movable impression member protruding from the inner core within a portion of the molding space so as to create a recess within an inner wall of the structure, and retracting the impression member into the inner core such that the impression member is cleared from the molding space. |
