Want to know what plastic finish is best for you? We first need to know what types of plastic finishes are there?
Plastic finishes are used by manufacturers to give the final appearance of the product and reduce the appearance of any blemishes or molding lines. These finishes are classified into grades classified by the Plastics Industry Association (SPI). SPI pointed out that plastic finishes are scattered in 12 different grades, from mirror gloss to dull matte. Generally speaking, these finishes can be divided into four categories:
1. Matte plastic finish
Matte and dark finishes are mainly used for die castings and thermoset parts. They are made of fine stone powder. It is foreseeable that the matte finishes are classified from C-1 to C-3.
2. Semi-gloss plastic finish
Created using different types of sandpaper, the semi-gloss finish is smooth, but not as shiny. B-1, B-2 and B-3 grades are polished from medium to medium to low. These finishes can be used on the exterior of products and parts that require a smoother finish.
