Coming out of the machine after machining, our parts are cleaned of any sharp edges and burrs while retaining marks. Without any added material, the part had a surface roughness of 3.2 μm (126 μin).
Band blasting cleans the surface of any impurities and peels coating through the propelling of blast media streams over the parts.
To increase surface hardness and dissipate heat, we use anodizing techniques to enhance the look of parts and blend well for painting and priming.
Electroplating reduces metal cations in the electrolyte solution, producing a metallic coating on a metal surface. This process can be used for purposes of corrosion and wear resistance, as well as for decorative purposes.
Working on metal and hard plastics, our polishing uses highly efficient machinery to get our parts between Ra 0.8~Ra0.1 for a cleaner surface.
We apply a thin layer of protective polymer with the corona discharge phenomenon to give our part a lasting finish that protects from impacts and prevents wearing down.
Our brushing technique uses abrasive belts over the material to create diverse patterns that match the parts’ structure and color.
Spray droplets can be dispersed uniformly or in fine amounts to cover a wide surface area and bring out greater color to the part.
Adding layers to metallic surfaces like steel, our black anodized technique improves appearance while maintaining durability.
We use chromate conversion coating or alodine to protect aluminum and other materials from corrosive elements, usually done before priming and painting parts.
Helpful in brand recognition or parts organization, we use laser carving that applies various printing methods during full-scale production to quickly embed barcodes, lettering and logos on the parts.
Introduction to POM
POM, also known as acetal or Delrin, is a type of engineering thermoplastic that boasts exceptional dimensional stability, stiffness, temperature resistance, and impact resistance. It can be made from either homopolymer or copolymer. POM is widely used for fabricating a variety of components such as pipe fittings, gear bearings, automotive parts, home appliances, consumer electronics, and more.
Information of POM
POM is a common materials for parts machining and manufacturing,below is some common information about POM.
