Case Studies

Even the most advanced technology becomes obsolete the moment it is achieved,
yet uniform clearance accuracy contributes to reliable mold manufacturing.

“Designing steel with one-hundredth precision.”
Strengthening technological capabilities through cold forging and precision machining equipment (SFG).

Seibu Electric wire EDM machines continue to improve mold precision and stability,
high-precision machining has generated new orders, and due to their high reliability, expansion is underway.

Established 41 years after its founding, we have established a strong foundation and management system. We have achieved unmanned nighttime operation, which is a characteristic of wire cutting.
