By converting small sheet metal parts with welded joints to zinc die casting, it may be possible to eliminate welding!
By converting small sheet metal parts with welded joints to zinc die casting, it may be possible to eliminate welding! Zinc die casting has a higher specific gravity compared to aluminum, resulting in a relatively increased weight. However, it has good fluidity during casting, and the flowability within the mold during casting is also excellent, allowing for thin-walled designs and high-precision casting at a level of 3/100. This enables high-precision casting that does not require post-processing once removed from the mold. Even parts that are welded from sheet metal, such as sensor covers made of sheet metal, may become more cost-effective overall by switching to zinc die casting, despite the mold costs. Additionally, since it is die casting, it allows for integration of other parts, enabling innovative designs for component unification. **Features** - Excellent fluidity during casting, enabling precision casting - Proven applications in gear parts for camera and lens autofocus, movable parts for semiconductor mounting machines, and in automobiles (such as seats) - Post-processing free with a precision of about 3/100 for palm-sized parts - A safe alloy used in children's toy cars

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.
