By replacing the brass color used in insert molded products, the cost of the color can be reduced by 50-60%.
By converting brass-colored materials to iron, we have achieved a cost reduction of 50-60% while also enhancing the pull-out strength and break (twisting) torque to levels comparable to brass products. Brass inserts and outserts are expensive due to the high copper content in the brass material itself. However, brass has become the mainstream choice due to its good workability, which ensures heat resistance (thermal conductivity), break torque (twisting torque), and pull-out strength during press-fitting into resin (induction heating). By switching to iron, which is a cheaper material compared to brass, we have reduced the cost of the collar itself while still meeting the mechanical requirements of the insert collar and achieving ironization. There is also a proven track record of this in vehicle engine rooms!

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.
