Application in powder metallurgy mold
General powder metallurgy molds, especially magnet molds, have a service life of only about 1 month before NGH coating is used. After using NGH coating, the service life can be increased to about 3 to 4 months. Some powder metallurgy molds have a service life of only 100,000 to 200,000 times before using NGH coating. After using NGH coating, the service life is increased to 400,000 to 600,000 times, and the service life of some special powder metallurgy molds can be increased to 70 times. ~800,000 times, the effect is very obvious.
Application on PCB Micro-drill
Drilling parameters (S125KRPM)
Number of layers: 8 layers Thickness: 41～48mils Layup: L 2/9 copper thickness after electroplating is about 1.6mil
Drill diameter: 0.3mm Coating type: NGH nano gradient super hard coating
Drill diameter | category | Blocks per stack | Speed KRPM | Drop IPM | Speedback IPM | Lifetime HITS |
0.3mm | Uncoated | 3 | 110 | 80 | 1000 | 1500 |
Coated | 3 | 110 | 80 | 1000 | 4500/6000 |
After comparison test:
After drilling 6000 holes of the coated drill tip, the positions of the holes are all within the range of 3 mil. Due to the serious collapse of the ordinary drill tip, some holes exceed the range of 3 mil, which confirms the drilling accuracy of the drill tip after NGH coating treatment. Better than ordinary uncoated drill bits;
From the drilling test situation, when the drilling life of the coated micro-drill is increased by more than 3 times, the drilling quality fully meets the requirements (the CPK value of the hole position accuracy is less than 3 mil, the CPK value is greater than 1.33, the hole wall roughness is less than 1.2 mil, and the hole wall nail head is less than 1.5 times);
The use of NGH-1 type coating can effectively save more than 30% of the processing cost of the drill bit. At the same time, because the effective use time of the micro-drill is greatly extended, it reduces a lot of downtime for drilling and replacement, directly improves the production efficiency, and brings obvious benefits to users. income.

project | Test category | |
1500 hours plunger bench test | 300 vehicle tests | |
With GIC coating | There is no problem in the test, the matching clearance is good, and the operation is normal | 1% wear does not occur within the set range |
No GIC coating | Parts are often worn during the test, and the fitting clearance is poor | There is a 3% chance that accessories will be unavailable due to wear and tear |
Tappet bench experiment of engine system
project | 500 hours bench test |
With GIC coating | The end face wears evenly, the parts have no notch, and the end face roughness is about 0.3 |
No GIC coating | The end face is unevenly worn, some parts are notched, and the end face roughness is about 0.5 |
At the same time of the rapid development of the high-speed sewing machine industry, the problem of oil leakage and wear resistance has become a bottleneck restricting the development of the industry. The application of GIC coating on high-speed industrial sewing machine products effectively solves this problem and realizes oil-free lubrication and super wear resistance. dual performance.

Features
The combination of magnetron sputtering and multi-arc sputtering technology can produce high-quality films with rich colors, including but not limited to; IP chrome, IP gold, IP tint, IP brown, IP titanium, IP imitation gold , IP black, IP champagne, etc.
Under the two physical deposition methods, the film layer and the substrate can easily form a diffusion layer, and the film layer has good adhesion;
The incident particle energy is high, so the hardness of the film layer is high, and it has high wear resistance and scratch resistance;
The film layer has high smoothness and is not easy to stick to fingerprints;
Good corrosion resistance of film layer
