We have been mass-producing and supplying insert molded products made from PPS materials, which are widely used in power electronics for electric vehicles such as HEVs and EVs, for many years.
As a one-stop trading company for plastic injection molded products, we have extensive experience and achievements in important safety components for drive and steering systems, as well as in electric systems, particularly in sensor housings, terminal blocks, and bus bars. Our employees include experienced engineers and quality technicians who are well-versed in mold design and molding conditions, and we utilize CAD to provide optimal proposals that excel in QCD (Quality, Cost, Delivery). We also have experience in responding to the PPS (Polyphenylene Sulfide) conversion of coolant control valves, which are central to the thermal management systems of electric vehicles as next-generation technology. As a technical trading company, we provide consistent support from the product planning stage through mold design, mass production, mold updates, and maintenance and discontinuation responses, and we are capable of handling production and sales both domestically and internationally. Our mold and molding factories offer proposals by selecting the most suitable factory from multiple partners, both domestically and internationally, tailored to our customers' needs, delivering finished products with an excellent balance of cost and quality.

Company information
Founded 91 years ago as "Yashima Automobile Parts Trading Company," our company originated from the automotive parts division of Yashima Motor Co., which was the general importer of Chrysler vehicles in 1926. Over the years, we evolved from supplying repair parts to directly providing mass-produced components to automobile manufacturers, in line with the pre-war and post-war trends of domestic automobile production. At the time of our establishment, the Toranomon area was referred to as Japan's Detroit, yet there were almost no domestic vehicles present, and we had been engaged in automotive-related business even before the domestic production of automobiles began. Today, we have transformed and grown into a technical trading company that directly supplies and sells mass-produced parts to major automobile manufacturers and construction machinery manufacturers. We support the development departments of manufacturers with technical proposals and assist the procurement departments with global parts sourcing, providing mass production solutions for a wide range of products, from resin molded products, semiconductors, electronic components, and sensors to inverters and onboard motors that make up electric vehicles. Notably, the next-generation onboard electrification components have significantly increased, with mass production sales reaching an annual scale of 6 billion yen.
