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 component of an automobile seat reclining mechanism. As shown in the photo, it has a complex shape consisting of an involute gear in the head and serrations in the shaft.

For a general cold forging manufacturer, it is possible to produce a part with "only an involute gear shape" or "only a serration shape" without cutting, but if two elements are included in one part, it is likely to be manufactured by a parts former + secondary machining process.

On the other hand, at Arai Parts Co., Ltd. which operates the "Cold Forging/VA/VE Center," we have realized product realization by only forming with a parts former, taking advantage of our die development capabilities and well-developed multi-stage formers.
Of course, we have succeeded in reducing the cost per part by eliminating cutting. Please contact us if you have a project that you are having trouble with.
