Hot/Cold Injection Molding: Which Approach Is Best for You?
Aug 10, 2022
Despite the many advances in injection molding technology, challenges remain in producing visually acceptable parts with high esthetic requirements, free of molded-in stress, and with high dimensional stability, as well as reliably filling thin walls with high flow lengths. In the early 2000s, several Japanese companies collaborated in developing a molding technology that could satisfy the most stringent surface-quality requirements of their demanding electronic consumer-goods clients. In 2002, Ono Sangyo Co., a leading contract injection molder with a substantial processing technology department, introduced and patented the Rapid Heat Cycle Molding (RHCM) process. In 2009, Matsui Manufacturing Co., the leading plastics...
