PRODUCT

Three promises for metal thermal treatment

Trust

We always keep the delivery date.

We deliver your products on the day you want. If the delivery date needs to be adjusted, our personnel will contact you.
We promise to make you confident that you can leave your products with us without anxiety.

Security

We will rush to your site.

We have production bases in the Kansai, Chubu, and Kanto regions. When you need consultation or business negotiation, our personnel will rush to your site from each base. We promise to provide a sense of security.

Sincerity

We do not escape from trouble.

If a problem is found with the quality of the product we delivered, we thoroughly investigate the cause using our advanced inspection equipment.
We promise to be sincere in not running away from trouble.

Carburizing

Carburizing

Carburizing quenching and tempering are performed mainly for steel tapping screws. Screws for precision instruments (micro screws, camera screws, and micro screws) can be also processed in Saitama.

Application

Tapping screws for construction and No. 0 screws for weak electric current

Non-oxidation Quenching and Tempering (Thermal Refining)

Non-oxidation Quenching and Tempering (Thermal Refining)

Non-oxidation quenching and tempering are performed for bolts of small to large sizes.

Application

Automotive bolts

Vacuum thermal treatment (for stainless steel)

Vacuum thermal treatment (for stainless steel)

Suitable vacuum quenching (bright quenching), vacuum nitriding treatment, and a solution treatment are performed for small mass-produced products and precision parts. The treatment increases intensity as well as brilliance.

Application

Tapping screws, drill screws, and mesh products

Solution thermal treatment

Solution thermal treatment

Solution thermal treatment is suitable for austenitic stainless steel. The treatment prevents not only corrosion resistance degradation due to deposits but also cracks generated after riveting.

Application

Tapping screws, drill screws, and mesh products

Vacuum thermal treatment (for dies and tools)

Vacuum thermal treatment (for dies and tools)

Suitable vacuum quenching (bright quenching) is performed for thick products, such as dies, tools, and parts. We also perform various types of annealing.

Application

Dies, tools, and small parts

WPC Treatment® (Machine Parts, Cutting Tools, and Dies) / Precision Shot Peening

WPC Treatment® (Machine Parts, Cutting Tools, and Dies) / Precision Shot Peening

The treatment improves fatigue strength, prevents wear due to lack of lubricants, and improves strength by alloying metal surfaces.

Application

Machine parts, cutting tools, and dies

Metal thermal treatment technician

We are committed to training our engineers to provide high-quality services to our customers with the latest technology and knowledge.
