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 high-precision pin used in office automation equipment.

The application is insert-molded into resin to serve as a fastening component. The key point is that a washer is integrally molded into the pin to prevent it from slipping out. Previously, the washer and pin consisted of two parts, but now they are integrated into the pin.

In addition, the tip of the pin is C-chamfered (45 degrees) to guide the user when inserting the pin. We can handle this kind of detailed processing for ease of assembly.

As for the machining process, after cold forging using a 2D3B header machine, groove cutting and M6 thread rolling are performed.

Arai Parts co., Ltd, which operates the "Cold Forging/VA/VE Center," can offer proposals for integrating products with two-part configurations such as this product. We can also provide integrated services such as screw machining and cutting for accuracy, and mass production of high-precision pins is also possible.
