Transfer moldingis a process where the amount of molding materials measured and inserted before the molding takes place. The molding material is preheated and loaded into a chamber known as the pot. A plunger is then used to force the material from the pot through channels known as a sprue and runner system into the mold cavities. The mold remains closed as the material is inserted and is opened to release the part from the sprue and 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 cavity.Transfer molding, unlike compression molding uses a closed mold, so smaller tolerances and more intricate parts can be achieved.
