We contribute to the improvement of the lifespan of press molds.
The ceramic film produced by our thermal CVD method, which is the beginning of our coating technology, has excellent adhesion strength and has contributed to the improvement of the lifespan of various press molds, including cold forging molds. While coatings such as PVD are currently thriving, our stable performance continues to be highly regarded even today.

Would you like to try depositing diamonds? We support everything from prototyping to mass production! We have also started selling standard conductive diamond electrodes.
Diamond is an insulator, but it can acquire conductivity by doping with boron. We will uniformly deposit conductive diamond over a large area while maintaining the chemical stability and strength of diamond. Diamond electrodes have a wide potential window, allowing for the decomposition and synthesis of difficult-to-decompose substances through oxidation and reduction reactions. By electrolyzing tap water with diamond electrodes, it is possible to directly produce high-concentration ozone water. Additionally, our unique pre-treatment for film formation improves the adhesion of the diamond film. *For more details, please contact us or download and view the catalog.
This is a widely used coating with a proven track record for pull-out dies and plugs!
At Towa Denko Co., Ltd., we handle "CVD three-layer coating," which allows us to obtain materials in various forms such as thin films, fine particles, bulk, and composites. The substances that can be synthesized are diverse, including ceramics, metals, semiconductors, and organic polymers, and it is applied in a wide range of fields from submicron fine processing represented by ultra-LSI to coating of piping materials with meter-scale membranes. 【Features】 - By stacking three layers of TiC, TiCN, and TiN on a substrate of cemented carbide to a total thickness of 5 to 6 μm, it is expected to prevent initial seizure and extend the mold life. - Wear resistance and anti-seizure properties are significantly improved. *For more details, please download the PDF or feel free to contact us.

Functional ceramic films of various types are coated in single or multiple layers using the thermal chemical vapor deposition method, enhancing the performance of the material with the resulting high hardness and high adhesion ceramic films.
CVD coating refers to Chemical Vapor Deposition coating, which is a chemical film formation method. In a state of atmospheric pressure to medium vacuum (100 to 10^-1 Pa), gaseous raw materials are introduced, and energy such as heat, plasma, or light is applied to excite and promote chemical reactions to synthesize thin films or fine particles. These are then adsorbed and deposited on the surface of a substrate, chemically coating it with ultra-hard ceramic compounds. By using thermal chemical vapor deposition, various functional ceramic films are coated in single or multiple layers at high temperatures (900 to 1100°C), significantly enhancing the performance of the material with the resulting high hardness and high adhesion ceramic films. Functions of CVD coating include: slip resistance, chemical resistance, heat resistance, water and oil repellency, hydrophilicity, wear resistance, electrical properties, and dimensional stability.
CVD (three layers) and TiC treatment available at all times (upon consultation)! The effective dimensions for coating treatment are φ490×800 mm inside.
The term "CVD method" is an abbreviation for Chemical Vapor Deposition, which refers to chemical vapor deposition. This technology involves heating a mixed gas to approximately 1000°C and causing a chemical reaction on the surface of the substrate to deposit materials such as titanium carbide (TiC), titanium carbonitride (TiCN), and titanium nitride (TiN). Even outside the scheduled dates, we have established a system for implementing CVD (three-layer)/TiC treatment, so we look forward to your inquiries. 【Inspection Equipment (Partial)】 ■ Micro Vickers hardness tester ■ Shore hardness tester, Rockwell hardness tester ■ Inverted metallurgical microscope ■ Desktop microscope + energy-dispersive X-ray analyzer ■ Microscope *For more details, please refer to the related links or feel free to contact us.
