松山技研 List of Products and Services

We would like to introduce our "Cation Electrodeposition Coating Process." Cation electrodeposition coating is a method that utilizes the electrolysis of water to precipitate ionic polymers insolubly on the surface of the object being coated, followed by washing and baking to achieve a cross-linked coating film. It is widely used as an industrial coating method. Additionally, by adjusting the electric charge, it is easy to obtain a uniform target film thickness. 【Features】 ■ Automation and labor-saving in coating ■ Uniform film thickness can be achieved ■ Good adhesion ■ Excellent corrosion resistance and appearance *For more details, please refer to the related links or feel free to contact us.

EV-X/FG-X is a low-temperature processed PVD coating. It is based on a TiAlN/TiN film, and further enhances sliding and adhesion properties with the EV/FG series. The EV-X/FG-X significantly improves adhesion and sliding properties compared to the EV/FG series, providing suitable coatings tailored to customer needs and costs. By improving sliding and adhesion, it can greatly extend the number of shots for molds compared to conventional methods. The extended lifespan of molds also reduces maintenance burdens. It demonstrates overwhelming effectiveness in drawing, bending, and punching for forging and press molds. 【Features】 ○ Low-temperature processed PVD coating ○ Base film uses TiAlN and TiN ○ Further reduction of macro particles ○ Achieves sliding similar to DLC with Ti-based films *Please contact us or download the catalog. Additionally, we will be exhibiting at "Automotive World" held at Tokyo Big Sight in January 2025. Dates: January 22 (Wed) - 24 (Fri), 2025 Venue: Tokyo Big Sight Booth Number: E-31-14

This document introduces a comparison of the characteristics of coating films (X series and Excellent series). Coating films can add various properties to materials. For example, a coating film that enhances sliding properties can reduce friction, thereby decreasing the energy required for movement. By adding such properties, it is possible not only to save energy but also to reduce material wear and extend its lifespan. This document compares the characteristics of coating films, such as "EV-X/BM-X," which combines hardness and heat resistance, and "FG-X," which improves sliding properties and adhesion, and presents them in a table. You can choose coatings based on your application and the points you wish to improve, so please make use of this information for your knowledge of coating films and product considerations. 【Comparison Items】 ■Appearance Color ■Hardness (HV) ■Film Thickness ■Processing Temperature ■Sliding Properties ■Heat Resistance *For more details, please refer to the PDF document or feel free to contact us.

The "MM Process Type S" is our proprietary technology that has been improved upon the MM process (sulfurizing nitriding). The "MM Process" enhances friction resistance by generating a lubricating sulfide on the surface of steel products, followed by a hard nitride. "Type S" further improves anti-seizing, anti-galling, and wear resistance compared to conventional methods by concentrating sulfur components in the sulfurizing nitriding layer. 【Features】 ■ The synergistic effect of the sulfide layer on the surface and the nitride layer formed inside provides heat resistance to the hardened layer. ■ It combines anti-seizing and wear resistance. ■ We accept test trials. *For more details, please refer to the PDF document or feel free to contact us.
