Plastic lamellae grinding disc molding process has a runner arrangement for creation of turbulent flow in the molding cavity

摘要

Plastic melt is injected under pressure into a molding cavity via tunnel gates and gates(14). Whie passing through the gates the solid material stream is converted into a flat turbulent flow and enters the molding cavity. An Independent claim is made for a multi-part molding tool for the process with tunnel gates(14) and flow disruptors(16) in front of and at a distance from the gate outlets(15).
