Mitsuba Mfg. Co., Ltd. Japan

Founded in 1930, Mitsuba has been supplying extruders to all major rubber and plastic product manufacturers in Japan. Our innovative, patented welding machines are also highly acclaimed. Mitsuba process equipment are now operating at every corner of the globe, spanning industries from automobiles, electronics, cable & wire, to construction, polymer processing, medical technology and more. Being the only extruder manufacturer in Japan that produces both rubber and plastic extruders, Mitsuba enjoys a scale advantage which is reflected in our technical and R&D prowess. We enjoy a dominant market share globally in extrusion lines that make ultra-fine coax cables that go into the hinges of notebook computers, mobile phones, and other compact IT gadgets. Test extruders, conductor preheaters, sizing troughs, and gear pumps are available at our factory in scenic Ueda City, surrounded by the beautiful mountains of Nagano, just an hour away from Tokyo. Nagano, of course, is world renowned for its "soba" noodles (Japanese grub like pasta, but "not extruded"). You can enjoy the changing seasons riding the bullet train any time of the year when you visit our factory. Our vast data and knowhow covering virtually any kind of polymer and curing (vulcanizing, crosslinking) process imaginable can become an enormous asset for your development team (fluoropolymers, silicone, silane crosslinked PE (monosil one-step), any kind of rubber, you name it! ). Since 1930, Mitsuba has been privately owned and managed by the same founding family with the kind of dedication, passion, and continuity you won't find at large publicly owned organizations. Our one hundred and sixty employees are knowledgeable, versatile, and totally committed to developing the best extrusion and welding technologies, gearpumps, and other polymer processes for our customers.
