Cold Forging & Header Processing Specialists

TECHNOLOGY

Reliable Processing Technology,
Trusted for Over 45 Years

Our productivity has been improved and our costs have been reduced thanks to cold heading. We are equipped with 2D3B–6-stage machinery, capable of processing various materials and shapes.

For small-lot products with strict precision requirements, we use NC lathes, enabling us to handle a wide range of products.

Our secondary processing makes it possible to handle complex shapes that are difficult to form by cold heading alone.
