Generally speaking, the coloring and surface texture decoration of plastic products can be completed during plastic molding. However, in order to increase the product's lifespan and improve its beauty, the exterior is usually subjected to secondary processing and various decoration treatments.
The methods for surface treatment of plastic products include:
1. Surface machining. Its function is to make the appearance smooth, shiny, and beautiful; The selected techniques include sanding, polishing, etc.
2. Surface coating treatment. Its function is decoration, beautification, anti-aging and corrosion resistance; The selected techniques include coating, printing (screen printing, transfer printing, transfer printing), film application, hot stamping, etc.
3. Exterior decoration treatment. Its role is to make the appearance wear-resistant, anti-aging, metallic luster, beautiful; The selected techniques include thermal spraying, electroplating, ion plating, etc.
1、 Frosted
Usually, it refers to plastic films or sheets that have various textures on their own rollers during rolling forming, and the transparency of the data is reflected by the different textures.
2、 Polishing
Polishing refers to the use of mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece, in order to achieve a bright and flat surface. The principle is the same as wiping shoes. Apply plastic evenly on a toothbrush with paraffin oil or kerosene, evaporate for a day, use silk (such as socks) to arrange and pull, wipe back and forth on the surface of the plastic, and then sun it.
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. Spray processing material request is in spherical powder form.
Function: Coloring, achieving a different texture, avoiding plastic aging, and corrosion resistance.
Plastic spraying technology process: annealing → oil removal → elimination of static electricity and dust removal → spraying → drying.
4、 Printing
Plastic printing refers to a technique of printing the required drawings on the surface of plastic parts, which can be divided into screen printing, curved surface printing (transfer printing), hot stamping, immersion printing (transfer printing), and etching printing.
