METHOD FOR CONNECTING SEVERAL PLASTIC COMPONENTS THROUGH INJECTION MOLDING AROUND THE SPRUE

摘要

Disclosed is a method for producing molded parts consisting of several components, using plastic processing machines. Plastified plastic material is injected into two cavities formed by the halves of a tool for each component. A sprue element is provided at least for the first component (1). The invention is characterized in that the sprue element (4) of at least the first component remains in the mold and is totally or partially encapsulated by injection molding by the next component (5) during one of the following working cycles. This reduces the number of additional working steps for the removal of the sprue and prevents eventual impurities in the environment, especially in the case of brittle material.
