There are many kinds of metal surface treatment in dalian, which can be divided into solvent cleaning, mechanical treatment and chemical treatment according to their different characteristics. Depending on the degree of oxidation of the metal surface, should be used in different ways.

As for thin oxide layer can use solvent cleaning, mechanical processing and chemical processing, or directly by chemical treatment, for severe oxidation of the metal surface, due to the oxide layer thicker, if directly using solvent cleaning and chemical treatment, not only deal with incomplete, also will waste a lot of cleaning agents and chemicals, using mechanical processing first. The mechanical treatment can effectively remove the rust, welding slag, oxide skin on metal parts, and can eliminate the welding stress, increase the adhesion between the anti-rust coating film and the metal matrix, thus greatly improving the anti-corrosion performance of metal parts.

Dalian metal surface treatment machinery treatment including shot peening, surface swelling, etc. Metal surface treatment technology can meet the requirements of corrosion resistance, wear resistance, decoration and surface roughness of metal parts, playing an important role in the development of metal parts manufacturing industry.
