"Raster processing" is a technology that forms only a tough diffusion layer without creating a compound layer. Since the process of polishing away the compound layer can be reduced, it contributes to cost savings. Additionally, by applying it to the substrate, the lifespan of molds and cutting tools can be extended several times compared to when only coating is applied, so we recommend composite hardening treatment using raster processing and PVD coating. [Features] ■ The nitrided surface consists only of a diffusion layer ■ The finished surface has good roughness and maintains gloss ■ Nitriding is possible in narrow slits and fine pores ■ Nitriding of cutting tools is possible ■ The release properties of resin molds are improved *For more details, please refer to the PDF document or feel free to contact us.

"Vacuum carburizing" is a method that increases the carbon content on the surface of low carbon steel and low carbon alloy steel, hardening only the surface layer through quenching. The surface becomes hard and wear-resistant, while the interior retains the material's flexible and tough state. It is mainly used in automotive parts and various machine components. Additionally, the spheroidization of cementite enhances machinability, while the fatigue strength of bearing steel and the toughness of tool steel are improved, resulting in better quality compared to gas carburizing. [Features] - Carburizing without grain boundary oxidation - Carburizing of fine hole inner surfaces, uniform carburizing - Carburizing of stainless steel - High concentration carburizing - Reduction of global warming factors *For more details, please refer to the PDF materials or feel free to contact us.

Introducing our "High Technology Coating," which is one step ahead. We offer a wide variety of PVD coating (Ion Plating) film types. PVD coating is a method of physically depositing a film on the surface of a substrate using metals (such as Ti, Al, Cr, Si, Nb, Mo, etc.) and gases (such as nitrogen and carbon) in a plasma state within a vacuum furnace. We are currently giving away coating samples! Please feel free to contact us. 【Features】 ■ Tribological films (smooth surface rough films) with low friction and excellent smooth surface roughness ■ Production of composite films, multilayer films, and gradient composition films ■ Uniform and smooth films that suppress droplets (macro particles) ■ Selection of film types according to usage applications ■ Strong adhesion and excellent decorative properties *For more details, please refer to the PDF materials or feel free to contact us.

The "G processing" is a low-distortion heat treatment technology that uses the ultra-flat distortion correction device "ULFLAT" to keep the thermal distortion of mold plates at a level of 0.01mm. As a result, the processing costs and time required for finishing the molds are reduced to one-eighth. This achieves cost reduction and a shortening of processing time. 【Features】 ■ Compatible with all types of steel (SKD, SK, SKS, etc.) ■ Reduces finishing work after heat treatment ■ Minimizes the amount of polishing required for mold plates ■ Almost no aging deformation of molds *For more details, please refer to the PDF materials or feel free to contact us.

Heat treatment refers to a process primarily involving the heating and cooling of iron products to enhance the strength and toughness of metal products, aiming for high performance and longevity. This important processing step is applied not only to the metal parts themselves but also to the molds necessary for part manufacturing. A revolution in the world of heat treatment has been brought about by Okaya Heat Treatment Industry, located in Okaya City, Nagano Prefecture. When processing metals such as iron, an unavoidable issue during the essential heat treatment process is "distortion." Okaya Heat Treatment Industry has been working on the development of unique technologies to suppress distortion, successfully reducing it to less than one-tenth of the conventional level and commercializing the results.
