豊島製作所 List of Products and Services

Toyoshima Manufacturing Co., Ltd. utilizes the concepts of both cold forging for "crushing and pressing" and sheet metal pressing for "punching, bending, and drawing" to propose suitable manufacturing methods. We have numerous examples of product processing using round bar materials, including "shafts," which are radiator cooling fan mechanism components, "pressure vessels" that integrate two parts through welding, and "gears" for large vehicles. By applying technologies such as sheet forging and ultra-precision punching to mass production, we provide products that exceed the conventional wisdom of press processing. 【Product Examples (Excerpt)】 ■ Shaft ■ Pressure Vessel ■ Planetary Carrier Plate ■ Gear ■ Clutch Case *For more details, please refer to the PDF materials or feel free to contact us.

The "AIDA UL-ti-mate" is a next-generation molding machine that seeks to maximize product precision, extend mold life, and achieve high versatility. By combining the slide guide "spherical shoe" with "composite materials," it is arranged in eight locations: front, back, left, right, up, and down. Preload is applied to the slide, achieving a "0" give clearance. Additionally, a high-rigidity ring frame is adopted, ensuring not only vertical rigidity but also high values for lateral rigidity. The entire frame effectively supports eccentric loads. 【Features】 ■ Achieves "0" give clearance ■ Adopts a nine-point support slide structure ■ Utilizes a high-rigidity ring frame structure ■ Incorporates a rodless mechanism *For more details, please refer to the PDF document or feel free to contact us.
