prototype metal
gence of high-speed molding machinery,the manufacturing of plastic products have speeded up.As the molding temperature is generally between 160 ~ 350 ℃,the poor fluidity and fast forming speed will make part of the molding surface temperature exceed 400 ℃ in a very short period of time. precision mprototype metalachining Electrical discharge machining(EDM) can create good mirror finishing effects and high quality surface finish;great stability will be showed when hardening. plastic tooling In addition,the thermosetting plastics filled with fiber tend to form inadequate fillings when they are too thin.How
