Product Description

Coating screw has three types.One is chromium plating. Mainly processing is by eltroplating. The other is HVOF. Another is PVD coating.
The best way is by PVD coat,because it can make very higher hardness then another two. The hardness can go up to 2500HV.
All detalis are shown clearly below.
Also with factory advantages.
Factory advantages as below:
1:5 factories. Except raw material is outsource. We manufacture all aspects by ourselfes.

1. 1. More than 20 pcs CNC machine center which can machine all aspects of products.
   2. Nitriding workshop with 5 ovens. We can nitride the raw material with more than 50 Tons totally one time by computer control system.
   3. Centrifugal casting workshop. We imported centrifugal casting equipment, which can produce various Fe-based,Ni-based&Co-based bimetallic barrels as per requirement.
   4. PTA bimetallic spraying workshop which not only can improve the effiency & bimetallic precision, but also can improve the anti-abration and anti-crossion of producs.
   5. Laboratory has all kinds of testing equipment. Like rockwell hardness tester,coordinate measuring machining,bruker spectrometer and metallographic microscope.
   6. Plating work shop can plate customized type,like chromium,TiN,CrN,AlTiN and tungsten carbide.
2. Around 350 experienced workers in every manufacturing procedure.
3. More than 6 engineers who can support us drawing,designing and technology.
4. Stron ERP system with all kinds of injection machine,extrusion machine and die casting machine's parts drawing. It is easy for us to recommend your ideal drawing.
5. 4 after-sale service people,suppose there is needing technical support. They can answer you in first time.
6. Capability: 5000TONS per month;60,000TONS per year.
7. Turnover: USD 30 million.
