Most of the electroplating processing plants used in vacuum plating processing technology have many advantages over traditional electroplating processes. First, vacuum electroplating can deposit low-potential metals that cannot be deposited by wet plating such as aluminum, titanium or zirconium. Reverberating gases and alloy targets are capable of depositing coatings from alloys to ceramics and even diamonds, and can be engineered as needed.

Secondly, because the adhesion, density, hardness, corrosion resistance and the like of the vacuum coating vacuum coating are suitably excellent, the deposited vacuum plating can be much smaller than the conventional wet plating, and the saving intention is reached. Moreover, it is still an electroplating technology without environmental pollution, because all the coating materials are deposited on the surface of the workpiece through the plasma in a vacuum environment, and there is no solution contamination, so the damage to the environment is suitably small.

Vacuum plating is done by spraying a primer on the material and then plating it. Since the material is a plastic part, air bubbles, organic gases are left in the injection molding, and moisture in the air is taken in when placed. In addition, since the surface of the plastic is not flat enough, the surface of the directly electroplated workpiece is not smooth, the gloss is low, the metallic feeling is poor, and bubbles, blisters and the like may occur, and after spraying a primer, a smooth and flat surface is formed, and The generation of bubble blisters in the plastic itself is eliminated, so that the effect of electroplating can be exhibited.

Vacuum plating is a method of heating a metal under high vacuum conditions to melt, evaporate, and form a metal film on the surface of the plastic after cooling. The method of heating the metal is to use the heat generated by the electric resistance, and also to use the electron beam. When vapor deposition is applied to a plastic product, it is necessary to adjust the vapor deposition time in order to ensure that the heat generated when the metal is cooled does not deform the resin.

Under vacuum conditions, the atoms and molecules of the evaporation material can be collided with other molecules during the flight to the plastic product, and the chemical reaction between the active molecules in the gas and the evaporation source material can be reduced, thereby providing the density, purity, and Deposition rate and adhesion.
