RHCM Overview
OSK (Ono Sangyo) is the original inventor having world-wide patent rights of Rapid Heat Cycle Molding (RHCM)™, the injection molding technology with rapid heat cycle of mold surface temperature assisted by steam, boiled water and other effective means. RHCM has been cross-licensed in 2001 with GE (General Electric) who gave another name to the technology, “Heat & Cool™”. Today, OSK is the only legitimate organization, in the world, who is able to assure compliance of intellectual properties to molders and customers for the patented technology under the name of either RHCM™ or Heat & Cool™.
