1、 Frosted
Frosted plastic generally refers to plastic films or sheets. During the rolling process, there are various patterns on the rollers themselves, which reflect the transparency of the material through different patterns.

2、 Polishing
Polishing refers to the process of using mechanical, chemical, or electrochemical forces to reduce the surface roughness of a workpiece, in order to obtain a bright and flat surface. The principle is the same as wiping shoes. Use paraffin oil and kerosene to evenly apply plastic on the toothbrush, evaporate for a day, and then use silk like socks to pull left and right on the plastic surface to wipe back and forth, and then sun it again.


3、 Coating (spraying)
Plastic spraying mainly involves coating a layer of plastic on metal equipment or components, which plays a role in anti-corrosion, wear-resistant, and electrical insulation. The spraying processing raw materials are required to be in spherical powder form.
Effect: Coloring, obtaining different textures, preventing plastic aging, and corrosion resistance.
Plastic spraying process flow: annealing → oil removal → elimination of static electricity and dust removal → spraying → drying

4、 Printing
Plastic printing refers to a process of printing the required patterns on the surface of plastic parts, which can be divided into screen printing, curved surface printing (transfer printing), hot stamping, penetration printing (transfer printing), and etching printing.
