4, Quality Control

1) Checking the raw material after they reach our factory------- Incoming quality control ( IQC)
2) Checking the details before the production line operated
3) Have full inspection and routing inspection during mass production---In process quality control(IPQC)
4) Checking the goods after they are finished---- Final quality control(FQC)
5) Checking the goods after they are finished-----Outgoing quality control(OQC)

The Military Specification referred to as MIL-DTL-5541, “Military Specification, Chemical Conversion Coatings on Aluminum and Aluminum Alloys” covers chemical conversion coatings formed by the reaction of chemical conversion materials with the surfaces of aluminum and aluminum alloys. The current specification (2009) is MIL-DTL-5541F, which superseded MIL-C-5541E in July 2006. The specification is approved for use by all departments and agencies of the United States Department of Defense (DoD). Although prepared specifically for DoD applications, the standard is used for many commercial applications as well.
The MIL-DTL-5541 specification covers chemical conversion coatings that form protective coatings by chemical reaction with aluminum and aluminum alloy; these coatings are categorized by the following types and classes.
Type I: Addresses compositions containing hexavalent chromium.
Type II: Addresses compositions containing no hexavalent chromium.
AND
Class 1A: Provides maximum protection against corrosion, whether painted or unpainted. This is a relatively thick film used as a final finish or pre-treatment to paint or powder coating, and it is typically gold, brown, or yellow depending on coating weight and alloy.
Class 3: Provides protection against corrosion where low electrical resistance is required. This is a thin film providing low contact resistance, and the coating weight is lower as is the corrosion resistance. There may be some advantages using this thinner film in bonding applications. This film typically appears to be a lighter color of gold.

We providing machining and manufacturing custom parts with material tungsten steel,tungsten alloys, copper tungsten, and aluminium alloys.
Tungsten steel is a type of metal alloy made from a combination of tungsten and iron. The addition of  tungsten to the alloy gives it increased hardness and resistance to heat, allowing equipment made from tungsten steel to maintain high performance and to resist wear at high temperatures.
For example: we use YG15,YG20  integrates cobalt-tungsten cemented carbide
Our Equipment : Milling machines,  EDM  (Electric discharge machines),linear cutting


Quality is our forte and we have clients spreading all over the world. We are committed to a well-defined and self-framed quality policy. The policy revolves around through and repeated checking of the tungsten material made parts by turret milling machine . We are the regular exporters of our products throughout Asia, Africa and several European countries.
