"Sakigake" is a cleaning device that utilizes the dissolving power of oil without using chlorine-based organic solvents, water, or alkalis. It first performs a pre-cleaning with high vapor pressure oil, followed by heating and reducing pressure to evaporate (vaporize) the cleaning oil for the cleaning process. The cleaning oil and the oil being cleaned are each separated and recovered by a regeneration device (special distillation apparatus) attached to the unit, allowing for reuse. This results in low operating costs and easy handling. 【Features】 ■ Does not pollute the environment (atmosphere, soil, groundwater, rivers, oceans) ■ No risk of fire or explosion ■ No toxic or hazardous substances used ■ Cleaning oil can be separated, recovered, and reused ■ Adhered oil is separated and automatically discharged *For more details, please refer to the PDF document or feel free to contact us.

"Direct Carburizing (Multi Carbo)" is a new concept carburizing method that combines gas carburizing and vacuum technology. This technology utilizes vacuum (reduced pressure) to drastically reduce carrier gas and only uses a very small amount of chain-like unsaturated hydrocarbon gas as the carburizing gas. Since the atmosphere does not contain oxygen components, the alloy components on the surface do not oxidize, resulting in a good finish. It is environmentally friendly, high quality, and reduces operating costs by half. 【Features】 ■ No grain boundary oxidation (oxidation of surface alloy components) ■ Carburizing of pores is possible ■ High concentration carburizing is possible ■ Extremely shallow carburizing (30-50μm) is possible ■ Vacuum hardening is possible *For more details, please refer to the PDF document or feel free to contact us.

"N-Quench" refers to a nitriding quenching process that allows nitrogen to penetrate and diffuse into steel, performing quenching from the austenite state. By introducing nitrogen and performing quenching, a surface hardness of about 850 HV can be achieved even with inexpensive SPCC materials, and it is possible to increase hardness within the range where nitrogen has diffused internally. The amount of distortion is about half that of carburizing nitriding quenching and is only slightly larger than that of gas soft nitriding. Additionally, the friction coefficient and seizure surface pressure are almost equivalent to those of carburizing nitriding and gas soft nitriding, and the wear amount is favorable, being 1/2 of carburizing nitriding materials and 1/3 of gas soft nitriding materials. [Features] ■ Reduction of quenching distortion ■ Pure nitriding: Shortened processing time ■ Soft nitriding: High hardness ■ Applicable to inexpensive steel types, not just specific steel grades *For more details, please refer to the PDF document or feel free to contact us.

"Gas Nitriding with Sulfur (Multinight)" is a surface modification technology that has been independently developed by our company, building on our multi-purpose gas nitriding method. The formation of a hard and lubricating sulfide-nitriding layer demonstrates excellent effects in improving wear resistance, seizure resistance, galling resistance, fatigue resistance, and corrosion resistance. 【Features】 ■ Good working environment, pollution-free processing ■ Improved seizure resistance, galling resistance, and wear resistance ■ Reduction of gear noise, deformation, and dimensional changes ■ Controllable concentrations of N and S ■ Gas consumption is about half that of gas soft nitriding *For more details, please refer to the PDF document or feel free to contact us.
