Producing high precision parts by powder injection molding technology Mold Research Co., Ltd. 270-5 Aoji-cho, Kusatsu City Established in 1998 TEL +81-77-516-0811 http://www.moldresearch.co.jp/ Yoshimitsu Kankawa Succeeded in developing organic binder (molding agent) that made mass production by powder injection molding technology possible of micron-size precision parts that were difficult to produce by machining. Production of precision parts that the world is paying attention now Powder injection molding technology is very much like the process to make a pottery from earth and water (earth as metal and water as organic binder). It is the technology to add organic binder to powder (metal, ceramics) and make product after the process of injection molding and sintering. Development and supply of good organic binder for metal powder was the key point for mass production. Pioneer of powder injection molding technology Mold Research Co., Ltd. is an R&D type venture company in the 8th year from its foundation, which started from consulting business for other companies on powder injection molding technology. By integration of metal field and chemical engineering field, it succeeded in developing organic binder (molding agent), original product of the company. It is a pioneer that opened the door for mass production and industrialization of powder injection molding technology for the first time in Japan. Recently, this technology has been rapidly increasing, being adopted for digital equipments including mobile phones, laptop computers, and digital cameras. Realized cost reduction in production process and rapid delivery In addition to the original organic binder, the company has developed single step system to continue sintering process and debinding process in powder (metal, ceramics) injection molding. Compared to traditional technologies, it can cope with complicated sizes and shapes and get high precision, time reduction, cost reduction, and rapid delivery. Metal molded object and sintered object Height 1.5 mm, Diameter of the hole 300 µm Ceramics object and sintered object Diameter 100 µm Sintering facility (single step system) 223
