Resistance Evaporation Vacuum Coating Machine

The resistance evaporation vacuum coating machine is a classic physical vapor deposition (PVD) equipment.

It uses electric current to pass through a crucible or boat made of high-melting-point metals (such as tungsten, molybdenum, and tantalum) to generate Joule heat to heat and evaporate the coating material (usually metal or certain alloys) placed therein, causing it to vaporize in a vacuum environment and then condense on the surface of a substrate (such as glass, plastic, metal, silicon wafer, etc.) to form a thin film.

When an evaporation material such as aluminum wire is mounted on a high resistance material, the evaporation material vapor is instantly evaporated and migrated to the surface of the substrate under the action of Joule heat generated by the electric current at high temperature, and deposited into a 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.

Resistance evaporation vacuum coating machine is an ideal equipment for medium and large batches of high-quality coating production.
