For the best surface quality for your CNC machining and die casting parts, a series of surface treatment services are provided for selection. More than the following surface finishes are available if you have other needs.

Polishing a finishing process through which to smooth the surface of an object using an abrasive or a work wheel
Sand Blasting also known as sandblasting or abrasive blasting, is a process of applying high pressure to push solid particles across the object surface at high speed to alter the surface roughness
Color Electrophoresis applying different colors on metal materials and products through electrophoresis techniques
Pad Printing special printing methods to transfer the color and image that you wanted on surfaces
Rubber Casting provide waterproofing for CNC machined parts and die castings in varying applications, available in different colors
Silk Screen Printing involves printing ink through stencils, applying for hardware products
Anodizing forming a thin layer of aluminum oxide on the exterior of CNC machined parts to increase the thickness and corrosion resistance
Plating including chrome plating, nickel plating and more, to change the properties of the metal surface or build up thickness for undersized parts.
Passivation use a light coat of protective material to create a shell for enhancing the corrosion resistance or reducing the chemical reactivity.

What is CNC Machining?

Computer Numerical Control machining, also known as CNC machining, is a subtractive manufacturing process that employs computer controlled machine tools to remove layers of materials from the stock and create the custom part through following a programmed instruction. A range of complex machinery from lathes and mills to drills and routers can be controlled to execute specific operations. So, the common types of CNC machining operations including milling, turning and drilling. CNC machining services can process metals, plastics, wood, glass, foam and composites according to the applications and machines. This process enables efficient production of high precision and high accuracy with the help of automation, also realizes cost-effectiveness in medium-volume production run.
