Dare can achieve tooth formation with minimal reduction in plate thickness! Running costs can also be kept low.
Toyoshima Manufacturing Co., Ltd. is engaged in the development of a unique pressing method that combines single-process cold forging and parts forming, establishing a flexible integrated production system that achieves high quality and low cost. In the "pressing method," the tooth shape is formed from sheet coil material in two processes. Since the number of molds for the tooth shape is kept to a minimum, maintaining the precision of the tooth shape is easy, and it also helps to reduce initial investment and running costs for the molds. 【Features】 ■ The fusion of pressing and forging methods allows for tooth shape formation with minimized thinning and reduction in plate thickness. ■ A longer effective tooth surface can be secured. ■ The tooth shape is formed from sheet coil material in two processes. ■ Maintaining the precision of the tooth shape is easy. ■ Initial investment and running costs for the molds are also reduced. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Examples of Production】 ■ HUB for CVT - Since the tooth formation is a single process, the tooth surface accuracy is almost the same as the mold (products that only use external teeth). ■ HUB for AT - Since both internal and external teeth are used, it is difficult to ensure the accuracy of the tooth surface. *For more details, please refer to the PDF document or feel free to contact us.
