PVD vacuum coating machine




Vacuum evaporation, sputtering and ion plating. They all deposit various metal and non-metal films on the surface of plastic parts by distillation or sputtering under vacuum conditions. In this way, very thin surface coatings can be obtained. At the same time, they have the outstanding advantages of fast speed and good adhesion, but the price is also very high, and there are few types of metals that can be manipulated. They are often used as functional coatings for more products, for example as internal shielding layers. There are two common electroplating processes for plastic products: water electroplating and vacuum ion electroplating


Air ion plating is also called vacuum plating. Vacuum plating is now a popular practice. The product has strong metallic feeling and high brightness. Compared with other coating methods, the cost is low and the environmental pollution is small. Currently widely used in all walks of life. The scope of application of vacuum plating


PVD vacuum coating machine has a wide range of applications, such as ABS materials, ABS+PC materials and PC materials. At the same time, its unit price is more expensive than water electroplating due to its complex process flow and high environmental and equipment requirements. The following is a brief introduction to its process flow: product surface cleaning-->removal of static electricity-->spraying primer-->baking paint-->vacuum spraying-->spraying top coat-->baking paint-->packaging. Usually, the practice of vacuum plating is to spray a layer of primer on the material before plating. Since the material is a plastic part, air bubbles, that is, organic gas, will be left during the injection molding process, which will inhale moisture in the air when placed. In addition, because the surface of the plastic is not flat enough, the surface of the workpiece that is directly electroplated is not smooth, has low gloss, and has poor metallic feeling, and there will be unfavorable conditions such as bubbles and blisters. After spraying a layer of primer, it will form a smooth and even surface, and eliminate the air bubbles and blisters generated by the plastic itself, thus showing the effect of electroplating
