PVD Coating
With equipment and technology developed by Nissin Electric, applying techniques and practical achievements developed over 35 years in Japan, in 2020 PVD Coating metal coating technology was officially present in Vietnam. Male. Equipment and technology imported directly from Japan, we advise and provide the most suitable coating to meet each customer's needs.
What is PVD Coating?
By creating a hard film layer of a few μm on the product surface, the coating helps increase hardness, reduce wear, increase slippage, reduce adhesion, and prolong the life of molds, tools, and machine parts. . This membrane is harder than nitriding and chromium plating. While the thickness is only 2-4 μm. In particular, the Hydrogen-free DLC coating is only 0.1 to 0.4 μm thick. The processing temperature is controlled below 450 degrees Celsius, so steel that has been tempered at high temperatures (SKH, SKD, etc.) will not be affected.
With 6 types of coatings: TiN, TiCN, TiALN, CrN, AlCrN, DLC and outstanding features, we are confident that we can bring customers the best coating quality, meeting short delivery times. best. Solve problems that arise in production.
