Japan Tohatsu mold spring

Tohatsu rectangular cross-section strong spring produced by Tokyo Clockworks. The spring is widely used in brakes of stamping molds, injection molds, mechanical equipment, punch machines, heavy machinery, wind power generation, ships, elevators, etc. Tohatsu successfully developed this product for the first time in Japan many years ago. It was later recognized as a Japanese standard and made a great contribution to the miniaturization of Japanese molds. Dongfa has always maintained its leading position in this field. It still occupies a large market share. Its excellent quality of accurate and stable load and long fatigue life has withstood long-term tests and is deeply relied on by users. In 2006, Tohatsu began to produce full-size standard mold springs in Japan for the first time, meeting the needs of European system customers. In a certain sense, Tohatsu brand has represented the authority of this type of products. The inventory has now been prepared in Tianjin and the company has officially started providing product services to users.
1. Dongfa spring series: strong spring, Dongfa standard spring, spring for large deformation, strong spring (Alfa)
2. Type classification: strong spring, Dongfa standard spring, spring for large deformation III Class springs can be distinguished by electrophoretic coating colors
3. Materials: Silicon chromium steel strong springs, Tohatsu standard springs, springs for large deformations, strong springs (Alpha): strong springs, Tohatsu standard springs, large Deformation amount springs and strong springs (Alpha) use materials with special-shaped cross-sections, which have greatly contributed to the miniaturization of molds. Dongha mold springs are manufactured under strict process management and undergo rigorous general fatigue testing and punching. Fatigue test, the resulting standardized product has guaranteed quality and can be used with confidence.
4. Selection of spring specifications: Determine the four parameters of the operating load, spring outer diameter, service life, and operating compression amount to determine what type of spring it is.
