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 special nut for an automobile sunroof mechanism. It is characterized by its square shape and the fact that it requires a small hole on the inside diameter.

The square shape is difficult to forge, and the small hole process is also very difficult, so a multi-stage parts former is the only way to form this product in terms of the number of processes required.

We have achieved a change in production method by trimming the flange using a parts former and only tapping the flange in the subsequent process. This has succeeded in reducing costs significantly compared to the case where all cutting is performed.

Arai Parts Co., Ltd. which operates the "Cold Forging/VA/VE Center" has abundant experience in manufacturing special nuts such as flanged square parts that require tapping as in the case of this product. Please contact us if you have any trouble with mass production of complicated or difficult-to-form parts.
