PROCESS FOR INJECTION-MOULDING PLASTICS

摘要

Process and device for injection molding plastics. The injection material charge is introduced into the mold to obtain an uninterrupted flow front by initially injecting the material into the mold through at least one first gate and through a subsequent gate or gates only after the flow front passes the subsequent gate(s). An injection molding device having separately and variously controllable valves located in the supply lines interconnecting an injection molding apparatus, mold and gates.
