Introduction of Development

■Design Technique

<Bolt・Nut Design・Design of Other Parts>

1. Design of the high-strength tightening bolts based on the Standards of VD 12230.
2. Design by in-house design procedure.

■Design Verification (evaluation) Technique

<Commodity's Design Verification >

1. Enforcement of design verification (evaluation) with various test fixtures.

■Processing Technology

<Cold Forging Technique>

1. Technology that challenges high-speed, highly accurate production of auto parts obtained by metal mold design technology from production of bolts and nuts.
2. High technologies to produce very small and thin-walled parts utilizing hardening through forging process.

<Plastic Processing Technology>

1. High technologies to reduce weight and size by applying various plastic-forming processes.
2. High technologies of rolling, extrusion, tube-bending, spool, deep drawing, hydraulic bulge, and hydraulic opposed-type stamping.
3. High plastic-forming technologies from any shapes of material, such as plates, rods or pipes.

<Surface Treatment Technology>

1. High technologies of functionally-graded material to give excellent wear resistance and heat resistance on the surface of steel.
2. High surface treatment technologies to adjust the friction coefficient of steel.
