Class 102 mold is a medium- to high-production mold. It is good for abrasive materials and/or parts that require a close tolerance. This mold is of high quality. Class 102 mold must go through fewer than 1 million cycles, and the base must reach a minimum hardness of 28 R/C. Like Class 101 molding surfaces, Class 102 molding surfaces must be at least 48 R/C. Temperature control measures are used in all cavities, cores and slide cores whenever possible. Guided ejection, slide wear plates, corrosive resistance and plated cavities may not be required.
