1. Surface machining.  The effect of plastic mold processing is to make the surface smooth, bright and beautiful;  The means used are grinding, polishing and so on. 

2. Surface plating.  Its effect is decoration, beautification, anti-aging, corrosion resistance; The means of plastic shell spraying are coating, printing, film, hot stamping and so on. 

3.  Surface decoration finishing.  The effect of injection molded plastic shell is to make the surface wear-resistant, anti-aging, metallic luster and beautiful;  The methods used are thermal spraying, electroplating, ion plating and so on.

A: scrub 

Generally refers to the plastic film or sheet, in the rolling molding, there are various lines on the roller itself, and the transparency of the material is reflected by the different lines. 

B: Polishing

Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method.  The principle is the same as the principle of polishing shoes, with paraffin oil, kerosene on the toothbrush evenly spread plastic, volatilize for a day, pull around with silk (such as socks), wipe back and forth on the plastic surface, and then sun it. 

C.spraying

Plastic shell spraying is mainly to coat a layer of plastic on metal equipment or parts, which plays the role of anti-corrosion, wear-resistant, electrical insulation and so on.  The raw material for spraying processing is required to be spherical powder.

D.Printing  

Printing refers to the process of printing the required pattern on the surface of plastic parts, which can be divided into screen printing, curved surface printing (pad printing), hot printing, penetration printing (transfer printing) and etching printing.
