Surface treatment is a method of artificially forming a surface layer with different mechanical, physical and chemical properties from the substrate on the surface of the substrate, is to clean, sweep, deburr, degrease, and descale the surface of the workpiece surface. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product and for machined parts. Our more commonly used surface treatment methods include mechanical grinding, chemical treatment, surface heat treatment, painting, etc. For different materials, we can carry out the following surface treatments：

	Common surface treatment
Materials	Steel	Chromate Plating、Hard chromium plating、Electroless Nickel/Nine/Zinc Plate、QPQ、DLC
		Black Oxide、SilverGolden plating、TIN PlatingTungsten Carbide Coating、sand blasting
		phosphating、TiN-plating、chromium plating、AlCrN COAT、Polyurethae coating,etc.
	Copper	Electroless Nickel、SilverGolden plating、Passivated、Cu-alloy anodizing black,etc.
	Aluminum	Anodize Clear、Anodize Black、Hardness Anodize Black/Clear、Aluminium alloy oxidizing
		chromate plating、Electroless Nickel、Anodize Blue/Red,etc.
	Stainless Steel	Passivation、Sanded、Orbital Sanded、Electro-polishing、degreasing、Oxidizing black,etc.

The surface treatment and plating of many products can be selected in a variety of colors, whether it is in function or the appearance of the product use requirements can better meet the needs of customers, customers can also be considered as a general reference standard in the design process!K-TEK specializes in machining various precision machinery parts, which can becustomized according to customers’ drawings or samples. The company has more than 10 years of precision machining experience, relying on ISO9001:2015 quality management system, strict qualitycontrol to provide customers with OEM/ODM services, product processing accuracy can be controlled within ±0.002MM, surface roughness (√) control in Ra0.4. We mainly focus on a variety of precision partscustomized processing, focusing on a variety of small batch production, while the number of products iscompletely without any requirements, one can also be processed, which is our competitive advantage!
