Overview

Tanabe Plastics Machinery Co., Ltd. (田辺プラスチックス機械株式会社) is a Japanese manufacturer of plastics processing machinery, headquartered in Ota-ku, Tokyo, with a second plant in Sagamihara, Kanagawa. The company was founded in January 1954 (Showa 29) by Kanichi Tanabe, who had previously conducted research on the physical properties of high-polymer materials and the fundamentals of plastics molding at the Tokyo Institute of Technology's applied mechanics laboratory, where he also worked on prototyping plastics machinery. Building on that research background, he established the company to develop and manufacture plastics machinery centered on extrusion molding equipment. The company's product range is built around extrusion technology. Its core offerings include general-purpose extruders and dies, film forming systems, laminating systems, sheet forming systems, pipe and tube forming systems, pelletizing systems (both die-face-cut and strand-cut types), foaming extruders, coating systems, composite/multilayer extrusion systems for multilayer film, sheet, pipe and profiles, and laboratory-scale extrusion systems for basic research. It also supplies special-purpose extruders for specialty resins and composite materials, along with ancillary equipment, and offers a freely adjustable extruder and special extruders. Tanabe Plastics Machinery serves the plastics processing industry both in Japan and overseas. According to its company profile, its export destinations include the United States, the United Kingdom, Taiwan, China, Singapore, Saudi Arabia, Spain, Indonesia, Malaysia, Thailand, South Korea, India and the Philippines. The company describes itself as having developed numerous machines in step with the rapid growth of the plastics industry, responding to customer needs and earning substantial trust over the years. The company's corporate mark expresses three elements it considers indispensable to machinery: Safety, Efficiency and Economy. Its representative director and president is Isao Watanabe. Tanabe Plastics Machinery remains a privately held, independent Japanese machinery maker rather than part of a larger listed group, and it continues to operate from its Tokyo head office and factory and its Sagamihara plant.

History

Tanabe Plastics Machinery Co., Ltd. traces its origins to the research work of its founder, Kanichi Tanabe. Before founding the company, Tanabe worked at the applied mechanics laboratory (formerly the aeronautical engineering department) of Tokyo Institute of Technology, where he conducted research on the physical properties of high-polymer materials in the post-war period and carried out basic research on plastics molding, while also engaging in the prototyping of plastics machinery. As the plastics industry grew, Tanabe sought to respond to that growth and to perfect his machine prototyping work. In January 1954 (Showa 29), he founded Tanabe Plastics Machinery Co., Ltd. to develop and manufacture plastics machinery centered on extrusion molding equipment. The company states that it provided customers with equipment matched to the rapid development of the industry and thereby earned substantial trust over the years. Over the decades the company broadened its extrusion-based product line. Its current catalog covers general-purpose extruders and dies, film forming systems, laminating systems, sheet forming systems, pipe and tube forming systems, pelletizing systems using both die-face-cut and strand-cut methods, foaming extruders, coating systems, composite/multilayer extrusion systems for multilayer film, sheet, pipe and profiles, and laboratory-scale extrusion systems for basic research, as well as special-purpose extruders for specialty resins and composite materials. The company operates from a head office and factory in Ota-ku, Tokyo, and a Sagamihara plant in Kanagawa Prefecture. It has exported its machinery to a range of overseas markets, including the United States, the United Kingdom, Taiwan, China, Singapore, Saudi Arabia, Spain, Indonesia, Malaysia, Thailand, South Korea, India and the Philippines. It remains a privately held, independent Japanese machinery manufacturer.
