We provide a consistent response within the factory for mass production processes, including material selection for automotive plastic magnets, mold design, tool development, injection molding, magnetization, and inspection!
Plastic magnets (bond magnets) used in automotive steering and switch areas, which incorporate magnetic sensors, are easier to handle, lightweight, and less affected by rust compared to metal sintered magnets, making them excellent in properties. The base resin materials can be selected according to applications and needs, including nylon-based and PPS, and complex shapes can be molded through insert molding and two-color molding. We can accommodate multipole magnetization and radial magnetization, providing comprehensive proposals for materials, properties, and shapes, and we will mass-produce them in domestic lines with proven mass production results.

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.
