Evaporation Vacuum Coating Machine

Evaporation vacuum coating machine (abbreviated as evaporation machine) is a physical vapor deposition equipment that uses the principle of thermal evaporation in a vacuum environment to deposit a thin film on the surface of a substrate.

It is one of the coating technologies with the longest history and the widest application.

Its core principle is to evaporate or sublimate the coating material by heating in a high vacuum environment, and the generated vapor atoms or molecules condense and deposit on the cooler substrate surface to form a thin film.

Large area ion discharge, high ionization effect, improved bonding strength, strong adhesion.

The ion distribution is uniform, which greatly improves the stability and uniformity of the film layer.

Good ionization effect, it is easy to coat plastic, resin, acrylic and other products.

Give full play to the ionization effect, do not spray primer on plastic products, directly coat the plastic products.

It is suitable for plating aluminum, nickel, chromium, tin, indium and other metal films and transparent metal films on the surface of cups, covers, handicrafts, decorations, mobile phone cases, toys and other products made of plastic, resin, glass, ceramics and other materials, so that the surface of the plated parts has a metallic feel or red, purple, blue, green and other bright colors.

The principle is relatively simple and easy to understand.

Fast deposition rate and high production efficiency (especially for large surface areas).

Wide range of depositable materials.

The film layer has high purity and good density.

Process parameters (vacuum level, evaporation rate, substrate temperature) can be easily and independently controlled.
