In addition to injection molding, our company also conducts gas-assisted molding and insert molding using vertical molding machines (including overseas locations). Polyamide resin containing 50% glass fiber is prone to uneven thickness in gas injection, but we have successfully achieved mass production. It is possible to reduce the amount of raw materials (resin) used and lower costs by shortening cooling time, and since we can lower the injection pressure, we can suppress the occurrence of burrs. 【Benefits】 ■ By applying pressure from inside the product, it is possible to suppress the occurrence of sink marks. ■ Reducing the thickness variation of molded products helps to minimize warping. ■ It is possible to produce molded products with high dimensional accuracy. ■ Cost reduction is achievable by reducing the amount of raw materials (resin) used and shortening cooling time. ■ Since we can lower the injection pressure, we can suppress the occurrence of burrs. *For more details, please refer to the PDF document or feel free to contact us.

We handle many precision parts for automobiles that are more difficult to process compared to general metalworking parts, which have strict requirements for positional accuracy, dimensional accuracy, and surface roughness set on different axes. We own over 100 automatic lathes capable of this processing, including those in overseas factories, and we achieve mass production of 1.5 million units per month for products being manufactured in these facilities. The processing technology from our domestic headquarters factory is continuously deployed to overseas factories, ensuring that we maintain and secure the same level of quality as in Japan. 【Features】 ■ We handle many precision parts that are difficult to process. ■ We achieve mass production of 1.5 million units per month for products of various sizes. ■ We have processing experience with a variety of materials, from mild steel to high carbon steel, alloy steel, and stainless steel. ■ We maintain and secure the same level of quality as in Japan, even overseas. *For more details, please refer to the PDF document or feel free to contact us.

Our company produces "solenoids," which generate a magnetic field by passing current through a coil, attracting a rod-shaped iron core and enabling linear motion. We can manufacture most components in-house using our production capabilities in our Chinese factory, as well as our expertise in cutting, forging, and resin molding technologies (including insert molding). Please feel free to contact us if you have any requests. 【Features】 ■ Cost reduction through increased in-house production ratio ■ Proactive value-added proposals through in-house design ■ Quality as the top priority *For more details, please feel free to inquire.
