Working principle of evaporative vacuum coating machine

Vacuum coating machine manufacturer's vacuum coating equipment The working principle of the evaporation vacuum coating machine The substrate that needs to be coated is called the substrate, and the coated one is called the target. The substrate and target are together in a vacuum chamber.

Evaporation coating generally heats the target material to evaporate the surface components in the form of atomic groups or ions. and deposited on the surface of the substrate to form a thin film through a film-forming process (scattered-island structure-scattered structure-layered growth). For sputtering coating, it can be simply understood as bombarding the target with electrons or high-energy lasers, and the surface components are sputtered out in the form of atomic groups or ions, and finally deposited on the surface of the substrate. After the process of film formation, a thin film is finally formed. Evaporation coating machine 1.jpg

The evaporation vacuum coating machine uses the resistance heating method to melt and evaporate the metal wire attached to the resistance wire in a vacuum chamber, and the evaporated metal molecules are deposited on the substrate to obtain a smooth reflective film layer, so as to achieve decoration and beautification. superficial purpose. It is an ideal equipment for surface decoration of cheap and high-quality plastic parts. Plastics with any background color can be plated into gold, silver, red, purple, blue, gray, black, colorful and other colors after vacuum coating to improve the product grade and make the appearance more luxurious.

The evaporation vacuum coating machine is widely used in plastics (ABS, PS, PP, PC, PVC), nylon, ceramics, resin, glass and other materials, toys, accessories, handicrafts, mobile phone cases, electronic products, lighting accessories, cosmetic packaging and other industries. High-power evaporation system, controlled by thyristor, high repeatability and stability, unique design of plated-through electrode, excellent workpiece rotation structure, stable and adjustable speed, large output and high yield.
