Transfer molding is a process where the amount of material is measured and inserted before the molding process takes place. The material is then preheated and loaded into a pot and a plunger is then used to force the material from the pot through the runner system into the mold cavities. The mold remains closed as the material is inserted and is opened to release the part from the runner. The mold walls are heated to a temperature above the melting point of the mold material; this allows a faster flow of material through the cavities.

Benefits of Transfer Molding

• Durable and dimensionally stable parts
• Prevents corrode or rust
• Impact resistant, chemical resistant
• Minimal release of airborne emissions during production
• Uniform thickness of parts
