The ion plating film is an ion sputter coating, and a DC bias power source is used for the conductive target; a non-conductive target is used, and a pulse bias power source is used. Some multi-arc ion coating machines may also require DC arc power or pulsed arc power.
The bias power supply is the bias electric field between the cathode and the anode where the sample is located, usually the cathode plus negative high voltage. The free electrons on the cathode surface are oriented to accelerate the emission under the effect of the electric field. The electrons are bombarded with gas molecules to make them ionize, and the electrons driven out by the gas are accelerated by the electric field, continuously ionizing other gas molecules, forming one after another, forming an avalanche effect, and the gas is struck. Wear to form a stable ionization current. At this moment, the ions are also accelerated, bombarding the target, driving out the atoms in the target and depositing them on the surface of the sample.

Multi-arc ion coating machine is used for different level hardware products. Usually, hardware and locks are built. Multi-arc ion plating equipment can be used. Medium and high-level products such as strap, case, eyeglass frame, mobile phone case and golf club. , sanitary ware, jewelry, etc., usually use arc / intermediate frequency (+ DC) magnetron sputtering composite coating equipment, according to the load size of the selection of large and thin models. The device can be decorated with gold, rose gold, brown, brown, bronze, blue and other decorative films.

What applications of vacuum coating machines in plastic products? We know that after the metallization of the surface of plastic products, the vacuum coating machine will be more widely used in plastic products, and the vacuum coating on the surface of plastic parts can be divided into functional and decorative coatings.
As a functional coating, it can improve the physical and chemical properties of plastic parts, such as improving the dimensional stability and electrical conductivity of plastic parts;
As a decorative coating, it can be made of plastic parts with metallic luster and can be made according to the actual decoration, such as gold, metallic blue, bronze, metallic green and metallic red.
Vacuum coating machines are widely used in plastic products. Plastics are easy to mold, light in weight, low in cost and non-corrosive. Plastic products are widely used, but their applications are limited, such as unsightly and high water absorption. It is easy to age, has poor heat resistance and poor mechanical properties. Through the application of vacuum coating technology, the metal surface of the plastic is metalized, and the organic and inorganic materials are combined to greatly improve the physical and chemical properties. The advantages are as follows:
1. Easy to clean, no dust.
2. Make the plastic surface conductive;
3. Improve the appearance, the surface is smooth, the metallic luster is colored, and the decorativeness is greatly improved;

4. Reduce the water absorption rate, the more times the coating is applied, the less the pinholes are, the water absorption rate is lowered, the product is not easily deformed, and the heat resistance is improved;
5. Improve surface hardness: the original plastic surface will be softer than metal and vulnerable to damage. Through vacuum coating, wear resistance and hardness are greatly increased;
6. Greatly improved weather resistance. Under normal circumstances, plastics age quickly in the outdoor, the main reason is caused by ultraviolet radiation, and after aluminum plating, aluminum has the strongest reflection of ultraviolet rays, so the heat resistance is greatly improved.
