Achieving a significant increase in productivity! We are introducing a vacuum carburizing furnace.

We have introduced a vacuum carburizing furnace that takes into consideration the Earth's environment and will become mainstream in the future!

Our company conducts "vacuum carburizing metal heat treatment," which achieves a stable surface hardness in a short time. There is no grain boundary oxidation, and there is no concern about cracking. It allows for low carbon dioxide emissions, making it an energy-efficient and clean process. In addition to improving product lifespan, it also enables processing that is difficult with gas carburizing.

【New Equipment Introduction】A vacuum carburizing furnace and a cart-type batch furnace have been introduced.

The CO2 emissions during processing are zero. Since carburizing is possible at high temperatures, processing time is shortened! It is also suitable for items with many machining holes and for small lot production of various types.

Our company conducts "metal heat treatment using vacuum carburizing," which achieves a stable surface hardness in a short time. In March 2025, new equipment including a vacuum carburizing furnace and a cart-type batch furnace was introduced at our Iwate factory. 【Details of the introduced equipment】 ■ Vacuum carburizing furnace (Factory No. 4) Internal dimensions: 600H × 660W × 1200L (same type as the current vacuum carburizing furnace) Processing capacity: 650kg/charge Maximum operating temperature: 1100℃ ■ Cart-type batch furnace (Factory No. 1) Internal dimensions: 1500H × 1200W × 2000L Processing capacity: 2,000kg/batch Maximum operating temperature: 900℃ *We have renewed our company brochure! *For more details, please download the PDF catalog or feel free to contact us.
