Molding process in which a quantity of mix is forced into a closed heated cavity or cavities from a heated chamber integral with the mold.
Unvulcanized rubber is placed in a chamber (called a pot), usually at the top of the mold, and the assembly is placed in a press. The press applies pressure to a piston-like plug in the open end of the pot, clamping the halves of the mold together and forcing the rubber to flow through the heated mold.
A process of forming articles by fusing a plastic material in a chamber then forcing the whole mass into a hot mold to solidify.
a process in which a quantity of compound is placed in a chamber (the transfer pot) in one part of the mold body, and the mold closure forces a projection (the transfer ram) into the chamber, thereby forcing the compound to flow through passages (sprues) into the mold cavity to fill it
Thermoset molding compound is fed from a hopper into a transfer chamber where it is heated to plasticity. It is then fed by means of a plunger through sprues, runners and gates of a closed mold into the mold cavity. The mold is opened and the part is ejected.
Transfer molding, like compression molding, is a process where the amount of molding material (usually a thermoset plastic) is measured and inserted before the moulding 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.
