The rapid development of these industries has also made the development of the plastic industry, especially the production and processing methods of plastic injection molded parts and New Car plastic parts.

To solve the problem of coating adhesion of New Car plastic parts, you must have some understanding of the process flow of New Car plastic parts painting.

The process flow of New Car plastic parts can be roughly divided into the following parts: blank grinding-chemical treatment-dust removal-primer spraying-color paint (or metallic flash paint)-glazing-baking-inspection-qualified products warehousing-unqualified products rework or paint removal.

It is understood that among these many process links, the important link to improve the adhesion of plastic parts coating is pre-painting pretreatment.

The purpose of pre-painting pretreatment of New Car plastic parts is to improve the adhesion of coatings to plastics and reduce various defects of coatings through a series of physical and chemical methods, thereby improving the quality of plastic coatings.
