We provide surface modification technology capable of mixed processing of various works.
Vacuum carburizing hardening is a surface hardening treatment that involves heating the workpiece under reduced pressure, allowing the necessary amount of carbon to diffuse and penetrate for the formation of the specified hardened layer, and then hardening it in cooling oil. It eliminates grain boundary oxidation and incomplete hardening structures, making it possible to improve mechanical strength. 【Features】 ■ Capable of forming a deep hardened layer in a relatively short time ■ Environmentally friendly ■ Easy to operate with simple controls *For more details, please download the PDF or feel free to contact us.

Company information
At Kuniyuki Thermal Engineering Co., Ltd., we inquire about specifications and applications, unravel phenomena based on principles, and consider the properties of metals to propose materials and surface treatments that satisfy mechanical and physicochemical properties. Whether it is "surface modification of already determined materials," "design from scratch – material proposals – suggestions for heat treatment methods," or "investigation requests due to defects – cause analysis," we are committed to challenging the development of new heat treatment and surface modification methods, even in industries where we have no prior experience. Please feel free to consult with us.
