发明名称 Method and apparatus for injection molding plastic objects comprised of at least two different materials
摘要 An apparatus and method provides that before, during, and/or after the plastic objects have been injection molded, a portion of the first plastic component, the second material, and/or a mixture of the two components is conveyed to at least one storage element with a variable volume. This element adjoins the flow path of the material melt. After completion of the injection molding process of the plastic objects and/or before the material is injected for the next plastic object to be produced, the plastic or the material stored in a storage element with a variable volume is conveyed to the flow path of the melt of the plastic or material. This frees the melt flow path of a mixture of the two plastic components and/or obtains a desired material mixture for producing the next plastic object.
