High-frequency heat treatment

High-frequency heat treatment

Partially harden. Optimal heat treatment with advanced technology.

Only the parts that require wear resistance can be hardened through surface hardening using electromagnetic induction. Due to rapid heating and rapid cooling, there is minimal oxidation and decarburization on the surface, and no thermal deformation occurs, resulting in excellent wear resistance. By changing the frequency, the depth of hardening can be adjusted, allowing for processing in a short time. Because very fast heating occurs, the know-how of skilled craftsmen is required. ● Heating coils suitable for the product shape are necessary. ● Detailed prior discussions will be conducted to perform heat treatment suitable for the material. ● Surface hardening allows the interior to remain as the original material while maintaining high toughness.

Flame hardening

Flame hardening

Local heating for processing complex shapes. Suitable for small-batch production of various types.

By applying high-temperature flames such as oxy-acetylene flames to locally heat the surface of steel parts, it is less affected by the shape of the workpiece. Skilled craftsmen accurately control the temperature using the color of the flame. Additionally, it is economical because it does not require fixtures or coils like high-frequency heat treatment (quenching) for the same localized heating process. ● It is used for processing complex machined parts that cannot be handled by high-frequency quenching. ● We conduct thorough prior discussions and perform heat treatment suitable for the material. ● It is economical because it does not require the cost of manufacturing special fixtures.

Vacuum heat treatment

Vacuum heat treatment

It is suitable for heat treatment of materials such as Ti, Inconel, and SUS thin plates, where oxidation prevention is difficult!

We would like to introduce our "Vacuum Heat Treatment." We adopt a method where all processes from heating to cooling are conducted in a heating chamber, preventing oxidation during cooling. Since vacuum is inert to metals, it is used as an ideal atmosphere, resulting in a good surface condition with excellent luster that requires little to no finishing. Additionally, the vacuum heat treatment heating is conducted solely by radiant heat, resulting in a very gentle temperature rise. This leads to a small temperature difference between the surface and the center of the treated item, allowing for uniform expansion and contraction, and enabling heat treatment with minimal distortion. 【Features】 - A vacuum pressure corresponding to 1×10−1 Pa retains 1 ppm of impurity gas. - Conducted solely by radiant heat. - The surface maintains its luster, and deformation is minimal, allowing for significant reduction in post-treatment processing. - No quenching oil is used, and there is no intrusion of oil into the chamber or vacuum furnace. *For more details, please refer to the PDF document or feel free to contact us.
