Ryukou Precision Engineering Co., Ltd. conducts mold design aimed at optimizing efficiency by anticipating detailed issues from the flow of resin during plastic molding to the extraction after molding. We possess the design capability to handle complex hot runner systems. Because we understand manufacturing, we also offer proposals from the design stage and advice on resins. Young employees actively engage in sales, proposing ideas unique to mold companies to clients such as consumer goods manufacturers, transforming the company from a subcontractor model to a "development proposal model." Furthermore, Ryukou Precision has many multi-skilled workers who can perform various processes from design to machining, assembly, and finishing all by themselves.
