Product Description

Purpose of plastic plating

The purpose of plastic electroplating is to coat the plastic surface with metal, which not only increases the beauty, but also compensates for the shortcomings of plastic, endows the properties of metal, and gives full play to the characteristics of plastic and metal. A large number of plastic electroplating products have been used in electronics, automobile, household products and other industries.

Plastic plating process

(1) Cleaning: remove the dirt and fingerprints left in the plastic forming process, wash with alkali, then neutralize with acid immersion and wash with water.

(2) Solvent treatment: the plastic surface can be wetted to act with the conditioner in the next step.

(3) Conditioning: coarsening the plastic surface into an internally locked concave hole to make the coating close and not easy to peel off, also known as chemical coarsening.

(4) Sensitization: adsorb the reducing agent on the surface, commonly used (stannous chloride) or other tin compounds, that is, Sn ions are adsorbed on the plastic surface with reductive surface. 

Compared with metal parts, plastic electroplated products can not only achieve good metal texture, but also reduce the weight of products. While effectively improving the appearance and decoration of plastics, they also improve their electrical, thermal and corrosion resistance properties. However, the selection of plastic materials for electroplating should comprehensively consider the processing performance, mechanical properties, material cost, electroplating cost factors such as the difficulty of electroplating and dimensional accuracy. Because of its structural advantages, it not only has excellent comprehensive properties and is easy to process and shape, but also the material surface is easy to erode and obtain high coating adhesion, so it is widely used in electroplating.

Advantages of plastic plating:

1. Easy and good forming

2. Light weight

3. Good corrosion resistance

4. Good drug resistance

5. Excellent electrical insulation.

6. Low price

7. Mass production
