Due to the operating environment being a clean room, it was not possible to use lubricating oil on the chain, and operating without lubrication became ideal, leading to the consideration of surface treatment. As a result of the "New Kanak Treatment," wear increased by 40mm over two months (without treatment) to only 2mm, reducing wear on the shaft portion. This made it possible to operate without lubrication, leading to environmental improvements by suppressing dust dispersion and increasing productivity by reducing maintenance frequency. 【Conventional Concerns】 ■ Want to suppress chain wear ■ Want to suppress chain elongation ■ Want to minimize lubricating oil usage *For more details, please refer to the PDF document or feel free to contact us.

In companies that manufacture automotive parts, resin pellets are sent to numerous molding machines to mold plastic products. When supplying the molding machines through piping from the tank, air is used to transport the pellets over long distances, crawling along the ceiling, which puts stress on the curves along the way, leading to holes forming in about a month. As a solution, "New Kanak treatment" was applied to the piping. The wear caused by the pellets was reduced, and the piping did not develop holes even after two years of use. 【Case Summary】 ■ Conventional Issues - Holes in piping due to wear ■ Treatment Effects (due to improved surface hardness) - Reduction in wear *For more details, please refer to the PDF document or feel free to contact us.

Due to the use of glass fibers as the material for the hopper chute used in the resin raw material manufacturing factory, we were struggling with wear and contamination. We implemented "New Kanak Treatment" to see if we could suppress wear and contamination by improving surface hardness through surface treatment. As a result, we were able to use it for four years without any issues, leading to increased productivity due to reduced replacements and maintenance. 【Case Overview】 ■ Conventional Issues - The hopper chute wore out quickly, requiring regular inspections and replacements. ■ Treatment Effects (due to improved surface hardness) - Reduction in wear *For more details, please refer to the PDF document or feel free to contact us.

To improve the lifespan of the core punch, we reviewed the selection of steel types. Previously, we used SKH51 material with CVD-TiC treatment, but the cause of the lifespan issue was the tip of the punch cracking in a ring shape, so we changed the material to carbide. By applying PVD (TiCN4μ) to the new Kanack treatment, we successfully achieved more than a 16-fold increase in lifespan compared to before. 【Case Summary】 ■ Previous Issues - The tip of the punch cracks in a ring shape - Peeling of the PVD coating ■ Treatment Effects (due to increased surface hardness) - Reduced wear - Suppression of chipping and peeling of PVD due to new Kanack treatment (undercoat treatment) *For more details, please refer to the PDF document or feel free to contact us.

In the resin injection molding factory, this is a counterpart material with 40% glass added. I had wanted to apply surface treatment for some time, but the dimensional tolerance was strict at 5µm, making it impossible to perform surface treatment. This time, we implemented the New Kanack treatment, which has minimal dimensional change. The mold life has doubled, and we were able to reduce the polishing process time. 【Conventional Issues】 ■ Dimensional changes ■ Wear ■ Time for the polishing process *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where "Kanack OX treatment" was applied to a pin. Due to the pin's withdrawal angle of 0.05 degrees, galling occurred at the aluminum weld area 150mm from the pin tip, resulting in a low lifespan. Therefore, we decided to test Kanack OX treatment, conventional nitriding, CVD (three-layer), and PVD (CrN) surface treatments. As a result, production became possible up to 12,000 shots, and the welding and galling at the tip were reduced, leading to improved productivity. 【Case Summary】 ■ Conventional Issues - Aluminum welding - Occurrence of galling ■ Treatment Effects (due to improved surface hardness) - Suppression of welding - Suppression of galling *For more details, please refer to the PDF document or feel free to contact us.

Traditionally, molds were used without treatment, resulting in a short lifespan of 7,000 shots due to galling and melting. Surface treatment had not been used until now, but it was implemented due to negative impacts on product quality and costs. As a result of the "Kanack OX treatment," the lifespan improved to 38,000 shots, which is 5.4 times longer than untreated molds. [Case Summary] ■ Traditional Issues - Melting - Galling ■ Treatment Effects (due to improved surface hardness) - Suppression of melting - Suppression of galling *For more details, please refer to the PDF document or feel free to contact us.

Traditionally, gas soft nitriding was used, and defects due to cracks occurred after 10,000 shots, leading to disposal. The causes were thought to be the occurrence of heat checks due to thermal fatigue and metal fatigue caused by warping during forging. After the new Kanack treatment, cracks also occurred after 16,000 shots, resulting in defects and disposal, but heat checks were suppressed. The updated type avoids operations until crack occurrence in the mold's lifespan and enables longer life by repeating reprocessing (removal of residual stress and addition of compressive stress) after 8,000 shots. 【Traditional Issues】 ■ Occurrence of cracks ■ Occurrence of heat checks ■ Metal fatigue *For more details, please refer to the PDF materials or feel free to contact us.

The "Kanak treatment" is our unique gas nitriding method developed in 1985 as a hardening treatment for non-magnetic stainless steel, which was considered difficult at the time. It is a diffusion treatment mainly composed of CrN and MoN, significantly improving issues associated with conventional nitriding, such as reduced toughness, dimensional changes, and surface roughness, thus enabling application across a wide range of fields. Based on this treatment, we will expand our processing lineup to meet the needs of many customers. 【Features】 ■ Low reduction in toughness with a diffusion layer-based hardened layer ■ Uniform effects can be achieved even on complex shapes and deep holes ■ Minimal change in surface roughness ■ Little warping, expansion, or dimensional changes ■ Reproducibility of treatment effects through repeated processing *For more details, please refer to the PDF document or feel free to contact us.

New treatment "EVOLK" for low Cr steel resin molds The hardness of P20 and P21 series materials is around 1000 HV. The surface roughness, weldability, and dimensional changes are similar to conventional materials, and due to the low-temperature treatment, dimensional changes are minimal. Additionally, for SKD11 materials, the diffusion layer depth is greater than before, making "EVOLK" effective for press molds as well.

"AKC processing" is a heat check/crack resistance treatment developed for aluminum die casting and similar applications. Based on the new Kanak treatment, we have identified conditions that significantly suppress cracking and optimized the treatment. While maintaining the advantages of the new Kanak treatment, such as weldability and electrical discharge machinability, the heat check/crack resistance has been enhanced. 【Features】 ■ Excellent heat check resistance ■ Welding operations can be performed without issues ■ Repeat processing is possible without compromising toughness ■ Composite treatment with other processes is possible *For more details, please refer to the PDF document or feel free to contact us.

The new Kanak processing is a composite treatment that combines Kanak processing and shot peening treatment, adding high residual compressive stress to the surface. The surface achieves higher hardness due to the peening effect compared to Kanak processing. 【Features】 ■ Excellent resistance to heat cracking ■ Welding operations can be performed without issues ■ Repeat processing is possible without compromising toughness ■ Composite processing with other treatments is possible *For more details, please download the PDF or feel free to contact us.
