The composition concept of vacuum electroplating machine vacuum electroplating machine

Vacuum electroplating equipment should be coated under vacuum working conditions, and there are many types of coating, mainly ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, etc. The vacuum electroplating machine is composed of many different parts, and each system has different functions, mainly including vacuum chamber, mechanical pump, vacuum test system, oil diffusion pump, vacuum pumping system, condensate pump and film forming control system, etc. Its main part is a vacuum chamber, the size of which is determined by the processed product and can be customized according to customer needs. The cavity is generally made of stainless steel, so it is strong, durable and not easy to rust. The degree of vacuum will directly affect the effect of the product, so the vacuum system is an important part. In general, machines with manual operation will be cheaper, and machines with high technical content will be much more expensive.

Coating behavior of vacuum electroplating machine under high vacuum degree

With the continuous maturity of coating technology, it has gradually expanded from a single industry to more industries and is widely used. Then we will learn about vacuum coating and vacuum electroplating machine products today.

First of all, we must first know what is vacuum coating. This is actually a technique for producing thin-film materials by physical methods. In the vacuum chamber, the atoms of the material are segregated from the heating source and hit the surface of the object to be plated. The vacuum coating is the coating behavior carried out under high vacuum degree. There are many types of such coating equipment, including vacuum evaporation coating machine, vacuum multi-arc ion coating machine, vacuum intermediate frequency magnetron sputtering coating machine, vacuum optical (electron beam evaporation) coating machine and other series of vacuum coating equipment. The main ideas here are divided into two types: evaporation and sputtering. The method of the vacuum electroplating machine is to spray a layer of primer on the material first, and then do the electroplating. Since the material is a plastic part, air bubbles and organic gases will remain during injection molding, and moisture in the air will be inhaled when placed. In addition, because the surface of the plastic is not flat enough, the surface of the directly plated workpiece is not smooth, the gloss is low, the metal feeling is poor, and there will be air bubbles, blisters and other bad conditions. After spraying a layer of primer, a smooth and flat surface will be formed, and the generation of bubbles and blisters existing in the plastic itself will be eliminated, so that the effect of electroplating can be exhibited.
