[Press Products] Molding of Automotive CVT Component "Hub Clutch"

Complex spline shapes are formed through a combination of squeezing and cold forging! Thickness control is possible.

Sanko has successfully formed side walls with uneven thickness by adding forging elements to the drawing process. In our unique molding experiments inspired by components of automotive CVTs, we completed the prototype mold in four processes (two forging drawing processes + two end face cutting processes). We can also accommodate considerations for press forming feasibility during development. We will devise suitable methods according to your requests, so please feel free to consult with us. 【Features】 ■ Formation of complex spline shapes through combined drawing and cold forging processes ■ Different thickness specifications can be set depending on the location ■ A total of four processes to reach the state shown in the image, excluding single press processing and cutting processes *For more details, please refer to the PDF materials or feel free to contact us.
