This time, we introduce the “piercing die” used at Apollo Kogyo.

This die was manufactured for mass-produced automotive components and is designed for long pipe materials.
By piercing multiple holes simultaneously in a single process, it significantly improves productivity as a process-reduction die.

The accuracy achieved is an impressive 1/100 to 1/1000 mm range.
This level of precision is supported by skilled technicians through careful finish grinding and final hand-finishing processes.

Because even the slightest deviation is unacceptable, we implement thorough quality control in die structure design, assembly accuracy, and surface finishing.

The “piercing die,” which serves as the heart of such tooling, is one of the most technically demanding processes in press forming.

We support a wide range of materials including steel, SUS, copper, and titanium.
Clearance design and heat-treatment expertise tailored to each material’s characteristics are essential.

Our facilities include 25t–80t presses, servo presses, and contour measuring machines. We also support special press processing, micro-fabrication, and oil-free processing.
Based in Saitama, we are capable of nationwide and overseas shipments.

If you are looking to achieve process reduction and quality improvement through high-precision dies, please feel free to contact us.
