Surface Finish Options for Injection Molded Parts
Surface finish is applied to parts after they have been machined to create a unique surface layer to meet the hardness, chemical resistance, and appearance requirements of the products. It depends on material properties and the application of the part. LEADRP offers the following finishing options for injection molded parts services:
Full Gloss is an Grade-A finish made by polishing, and it creates glossy surfaces on injection molded parts.
SPI Standard: A1, A2, A3
Semi-Gloss is a grade-B finish options made by grit sandpaper, and it creates a slightly rougher finish than grade-A parts.
SPI Standard: B1, B1, B3
Matte is a Grade-C finish options made bygrit sanding stones, and it creates a non-glossy surface texture.
