No soot generation (suiting)!
◯ No grain boundary oxidation, and the finish surface is good. ◯ High concentration carburizing is possible. ◯ Carburizing into pores is possible. ◯ No CO2 emissions from furnace exhaust. ◯ Carburizing time is about half compared to gas carburizing. ◯ The amount of carburizing gas used is less than 1% compared to gas carburizing.
It reduces distortion and enables high strength and long lifespan.
Our company has introduced a vacuum carburizing furnace to meet our customers' high value-added demands and to respond to the BCP (Business Continuity Plan) needs of parts manufacturers by outsourcing. We own two state-of-the-art large vacuum carburizing furnaces. Furthermore, due to fully automated control from the cleaning process, loading into the quenching furnace, heat treatment control, to discharge after processing, unmanned operation is possible, establishing a stable production system. Please feel free to contact us if you have any requests. **Benefits of Vacuum Carburizing Heat Treatment at Our Company** - Further performance enhancement, high strength, and longer lifespan - Prevention of breakage and defects - Uniform distortion within individual parts - Heat treatment with minimal distortion - Significant reduction in lead time, etc. *For more details, please download the PDF or feel free to contact us.*
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.
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.
