Title:
PLASTIC INJECTION MOLDING AND PROCESS
Document Type and Number:
WIPO Patent Application WO/2019/083787
Kind Code:
A3
Abstract:
A method of injection molding uses different mold inserts, such as lead frames, to selectively control material flow in order to produce different parts in a common mold. One mold insert can have a different geometry than another mold insert so that molten material is either blocked or allowed to flow through corresponding portions of the mold inserts. By changing out the insert used for injection molding, insert-molded plastic parts produced in the mold can differ by at least one part feature.
