INJECTION-MOULDING PROCESS FOR PRODUCTION OF A COMPONENT WITH AT LEAST TWO FUNCTIONAL COMPONENTS DESIGNED TO BE MOVABLE SEPARATELY FROM ONE ANOTHER AND RELATIVE TO ONE ANOTHER

摘要

An injection-moulding process for production of a component with at least two functional components designed to be movable separately from one another and relative to one another in a shared injection mould (10) encompasses the following steps: injection of flowable moulding composition into at least one first mould cavity (26) to form a first functional component using a first injection pressure and a first hold pressure, injection of flowable moulding composition into at least one second mould cavity (28,30) to form a second functional component using a second injection pressure different from the first injection pressure and a second hold pressure different from the first hold pressure, where one injection pressure, from the first injection pressure or second injection pressure, higher than the respective other injection pressure, and the hold pressure associated with the higher injection pressure higher than the respective other hold pressure have been selected in such a way that the functional component formed using the higher injection pressure and using the higher hold pressure has negative shrinkage.
