For all those who are concerned about the quality and cost of mass-produced parts for automobiles, robots, precision equipment, etc.

This example is a sleeve for automotive parts. Forging is not suitable for square shapes like the one shown in the photo, but we finished it by heading and cutting in order to realize cost reduction from total cutting.

The body part is a concave semi-circle shape to hold the mating part. The rough shape was achieved by forging and finished by cutting to achieve parallelism of the seating surface.

Arai Parts Co., Ltd, which operates the "Cold Forging/VA/VE Center," specializes in process design that considers not only heading and rolling but also secondary processes such as cutting and pressing.
