Surface Treatment


Surface pretreatment:

Oil → washing → rust prevention → washing → surface adjustment → washing → phosphating → washing → washing → drying

Purpose and importance of pretreatment

The purpose of pre-treatment is to obtain a good coating. As the above stamping parts will have oil, oxide rust, dust, rust and corrosion on the surface during manufacturing, processing, transportation and preservation, if not removed, it will directly affect the performance and appearance of the coating.

Meaning of pretreatment

Precoating, coating and drying are the three major processes of coating process, among which precoating is the basic process, which has important influence on the quality of coating, service life of coating and coating appearance.

The surface of the workpiece after degreasing, derusting and phosphating is clean, uniform and free of grease.
