Available Surface Finishes Class
Smooth and glossy finish
If your plastic parts require the smoothest finish, SPI grades A1, A2 and A3 are recommended. The molds in these grades will use hardened tool steel, the surface of the mold is polished by grit diamond. The mirror gloss provides a smooth gloss almost like a mirror. Products such as sun visors, plastic mirrors and optical products are made using such finishes.
Semi-glossy finish
If your plastic parts require the Semi-glossy finish, SPI grades B1, B2, and B3 are recommended, the semi-glossy finish is a good way to remove the processing, tooling marks. In the mold with a semi-glossy finish, grit paper will be used for grinding.
Matte finish
For plastic products that need a matte finish, we recommend SPI grades C1, C2, C3. The mold used for the matte finish is polished with gritstone. Matte finish is widely used in industrial parts, consumer goods, and other fields.
Textured finish
SPI grades D1, D2, and D3 are recommended if the part requires a textured finish. Molds for textured finishes are first ground with the dry blast and then dry sprayed with alumina and sometimes glass beads. A textured surface provides a good grip quality, conceals deformations and traces, and sometimes even helps to mask fingerprint stains.
Additional Finishing and Coating Options
Finishing or coating is applied after machining and can change the appearance, surface roughness, hardness, and chemical resistance of the produced parts.
- Polishing
- Pad Printing
- Silk Screening
- Custom Color Painting
- Laser Marking
- Heat Staking
