As Machined |
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 |
Band blasting cleans the surface of any impurities and peels coating through the propelling of blast media streams over the parts. |
 |
Anodizing |
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 |
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. |
 |
Polishing |
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. |
 |
Powder coating |
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. |
 |
Brushing |
Our brushing technique uses abrasive belts over the material to create diverse patterns that match the parts’ structure and color. |
 |
Painting |
Painting involves Spray droplets can be dispersed uniformly or in fine amounts to cover a wide surface area and bring out greater color to the part. |
 |
Black Anodized |
Adding layers to metallic surfaces like steel, our black anodized technique improves appearance while maintaining durability. |
 |
Alodine |
We use chromate conversion coating or alodine to protect aluminum and other materials from corrosive elements, usually done before priming and painting parts. |
 |
Laser Carving |
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 Polypropylene
Polypropylene (PP) is a material that is typically white and translucent and is resistant to corrosion while also possessing good toughness. Its most notable characteristic is its versatility, as it is suitable for use in a variety of processing methods and applications. The material's value and versatility can be attributed to its outstanding chemical resistance, being the bulk thermoplastic with the lowest density and highest melting point, and its moderate cost. To enhance its blow molding and thermoforming properties, high melt strength grades of PP have been created.

Material Properties
There are common Subtypes of Polypropylene.
Subtypes | Tensile Strength | Yield Strength | Elongation at Break | Hardness | Maximum Temp |
PP | 23 – 33 MPa | 30 – 32 MPa | 8 – 12 % | 65 – 102 HRR | 80 – 130 °C |
PP+GF(30%) | 68 – 85 MPa | 2.1 – 3.4 % | 110 HRC | 100 °C |
