This flow generates considerable heat, which raises the temperature of the materia] and homogenizes it. Curing takes place by cross-linking. Because the rcsir. 15 molten 05 it en¬ters the molds, the complexity of the parts and the dimensional control approach those of injection molding.
Typical parts made by transfer molding arc electrical and electronic components and rubber and silicone parts. The process is particularly suitable for intricate shapes with vary¬ing wall thicknesses. The molds tend to be more expensive than those for compression mold¬ing. and seme motcrkl IS left in the channels of the mold during filling. (See also Resir. Transfer Molding. Section 18.12.1.)
