Fine Coating (PVD coating)
Upgrade your product with PVD coating!!
Handling type: TiN / TiCN / TiAlN / CrN / AlCrN / DLC
We are developing PVD coating business in Nissin Electric Vietnam by making the most use of technology and achievements we have developed in Japan. By coating surfaces of molds, cutting tools and various parts, it is possible to improve wear resistance, oxidation resistance, corrosion resistance, slidability, and mold releasability. As a result, tool, die life can be improved, high-speed dry processing can be supported, changing to oilless and low-cost materials can be proceeded.
We will propose the most suitable coating for your purpose.
STARTED FINE COATING (FC) BUSINESS Coating service for cutting tools, mold die and automobile Manufacturers.
(GOLD) TiN fine coating The "GOLD" is TiN (Titanium Nitride) coating. It has 600degC heat resistance, superior anti-wear, anti-corrosion resistance. It can be used for not only the cutting tools, but also die, wire-cutter, plastic injection parts and so on widely. |
| |||||||||||||||||||||||||||||||||||
(CN) TiCN fine coating "CN" is TiCN (Titanium-carbon-Nitride) coating. The advantages are high film hardness and good sliding property because of the effect which contains carbon. It has approximately 500degC heat resistance, anti-wear and anti-sticking property. It is suitable for the cutting tools, punch, die, pin and so on. |
| |||||||||||||||||||||||||||||||||||
(ENDULO) TiAIN fine coating The "ENDULO" coating is mainly structured by TiAIN (Titanium Aluminum Nitride). It has a high temperature anti-oxidation resistance up to 800degC because of the effect which contains aluminum. It is suitable for dry, and high speed cutting tools. Our coating condition are optimized for the tool kind or tool materials, so an excellent tool performance will be obtained. |
| |||||||||||||||||||||||||||||||||||
(DULA) CrN fine coating "DULA" is CrN (chromium nitride) coating. It has about 800degC heat resistance and anti-wear property. The Vickers hardness of wet plating hard chromium is about 1,000. But in the case of PVd coating CrN film, it is about 1,600, much harder than wet planting. It means anti-wear property is superior to wet plating. Furthermore, it has an excellent anti-sticking property against a nonferrous metal. It is applied for example the cutting tools for copper material |

(SC) Aluminum Chromium Nitride SC (Aluminum Chromium Nitride series) coating is based on AlCrN, and having heat resistance up to 1100 °C Which other coating does not have. This coating hardness does not drop under the high temperature, demonstrates optimal performance For process tool under the severe temperature condition such as dry gear cutting, aluminum diecast, Morover this has high hardness, and is also applied for drawing die. |

WHAT IS "PVD COATING" ? An abrastion occurs first of all the "sur-face". |

The PVD is such coating technology that forms a few micron hard film on tools. The hardness of PVD is higher than tungsten carbide super-hard material. In comparison with hard-chromium, nitriding too, the PVD film is much harder. The only few microns film is improves anti-wear property dramatically. Because the thickness is a few microns, we can avoid the dimension changing problems except the application that require very precise accuracy. Furthermore, the hardness of high temperature tempering steel such as SKH,SKD is not lost because the coating temperature is controlled on 450°C. Our PVD coating service can be selected among four kind of film as following table. Our engineer will advise which film is most suitable on your application.
