Method and equipment for supplying a mould release agent

摘要

Method to supplying a spray system on a moulding machine, esp. a pressure diecasting machine, with liquid release agent, where the release agent is sprayed on a mould, surplus release agent is recovered and recirculated and fresh release agent is added. The recovered and fresh release agent (16,18) is fed in separate lines (32,38) to the spray head (12) at differential pressures p1 and p2 and only the release agent under higher pressure is admitted to the spray head (12). Equipment for the above is also claimed.
