DOWAサーモテック List of Products and Services

We have developed a plasma nitriding technology called "DC Coat R," which combines traditional PVD treatment. This new technology can shorten processing time compared to other nitriding treatments. Additionally, it significantly improves longevity, stress limits, and fatigue resistance. Moreover, during processing, it is an environmentally friendly surface modification process with no direct carbon dioxide emissions. ■Features ◎Reduction of oxidative wear with Cr-based films (high-temperature oxidation resistance) ◎Low friction coefficient achieved through finishing processes before and after treatment ◎Improved adhesion of CrN films through controlled plasma nitriding treatment ◎Increased compressive strength of the substrate due to controlled plasma nitriding treatment, enhancing resistance to high surface pressure strength ■Specific Product Examples ◎Cold forging dies ◎Press dies (high-tensile steel plates, general SUS materials, drawing dies, etc.) 【Effects】 Fatigue strength, adhesion, wear resistance, heat resistance 【Applicable Steel Types】 Applicable to all iron-based metals *For more details, please request documentation or view the PDF data available for download.

This is a surface hardening method that generates glow discharge in a dilute mixed gas atmosphere of nitrogen and hydrogen at several hundred pascals, simultaneously heating the workpiece and promoting nitriding due to ion impacts. Plasma nitriding is a processing method that is completely different from conventional nitriding methods, and it is currently being widely used for various mechanical parts, precision components, injection molding machine parts, and various molds, including automotive parts. In particular, our equipment features a built-in heater that allows for separate control of nitriding temperature and discharge conditions, making it a groundbreaking system that ensures uniform and excellent quality even in large capacity processing and large part treatment. - Features of Plasma Nitriding - (1) Nitriding can be performed only on the necessary parts (ensuring reliable anti-nitriding) (2) Minimal thermal distortion (3) A tough compound layer is obtained (4) It is the cleanest manufacturing method.

By coating with "Chrome Doppe-N," the 'corrosion resistance,' 'wear resistance,' and 'release properties' are dramatically improved, significantly extending the lifespan of mechanical parts and molds. ★ Due to low-temperature processing, there is almost no dimensional change for precision molds and parts. ★ It is a pollution-free treatment with no generation of harmful substances. 【Application Examples】 - Transmission parts - Press molds - Ferrite forming punches - Resin molding molds - Powder molding molds - Glass molds - Injection molding machine parts - Various semiconductor manufacturing equipment parts

We have commercialized "Sem Ion Plating," which significantly improves upon conventional ion plating technology, and we offer contract processing services. Please take advantage of Sem's cutting-edge technology that achieves "high quality," "long lifespan," and "low cost." 【Features of Sem Ion Plating】 - Significantly upgraded from conventional ion plating coatings. - Fewer droplets, with excellent adhesion, durability, and smoothness. - Creates a robust coating through composite processing with the formation of an intermediate layer. - Fewer droplets that lead to a decline in coating quality. Achieves cost reduction through a significant increase in processing capacity. *If you provide samples, we will conduct test coatings. For more details, please contact us or refer to our catalog.

"DOWA-Low Temperature DLC" is a coating process that forms a DLC film with excellent wear resistance, adhesion resistance, and low friction by using our unique PVD + P-CVD process. By equipping the film deposition device with a high-voltage pulse power supply, we have achieved an improvement in wear resistance while maintaining the smoothness of the DLC film surface. It is particularly suitable for countermeasures against material adhesion in aluminum press processing molds. 【Features】 (1) Further low-temperature treatment (180-250°C) compared to conventional PVD coatings (2) Extremely smooth film surface due to a droplet-free process (3) Low friction with excellent lubricity (4) Widely used in manufacturing, such as press molds and sliding jigs! *For more details, please contact us or refer to the catalog.
