Multi-arc magnetron sputtering multi-function ion vacuum coating equipment uses physical vapor deposition technology under vacuum to deposit titanium nitride and other films on the substrate. It combines multi-arc ion plating technology, cylindrical target and magnetron oil ion plating technology, and can be used alone or simultaneously to obtain various layers containing a continuous transition layer.

Multi-arc magnetron sputtering multi-function ion vacuum coating equipment is simple to manufacture, easy to use, low in operating cost, pollution-free, and economical. Its double vacuum chamber can work alternately, which can double the work efficiency and save investment. The main performance indicators of the equipment are as follows: coating chamber ultimate vacuum 1.3 & times; 10 < & rsquo; -3 > Pa; vacuum time (from the atmosphere to 6.67 & times; 10 < & rsquo; -3 > Pa) & les; 20 min; The rate is 1Pa/h; the working period is 1h; the arc current is 60~90A; the arc voltage is 18~21V; the magnetron oil target power is 10~36kW. The equipment has sold dozens of sets at home and abroad and achieved good social and economic benefits.

The common process of cell phone lenses, hardening: usually the surface hardness of the sheet after forming is low, so the surface of the lens needs to be hardened. It can be hardened on one side or hard on both sides. The hardening principle is to increase the hardness of the resin surface by adding a harder coating to the surface of the resin. The hardening method of the lens mainly includes: dipping the lens in the hardening liquid and spraying on the surface of the lens (Spray coating). The spray coating method is suitable for use on large flat plates, but the disadvantage is that the flatness is not easy to control. The Dipping method can be controlled to a fairly high flatness and is suitable for smaller lenses. By hardening, the surface hardness of the lens can be improved by 2 or more. Since the folding/reflecting rate of the hardening liquid is different from that of PMMA and PC, the phenomenon of rainbow is likely to appear on the surface of the lens after strengthening. The phenomenon of rainbows on PCs is more pronounced and difficult to avoid. The area of the hole and the uneven surface of the lens tends to cause hardening liquid to accumulate during hardening, so care must be taken when designing the structure. The strengthening process requires a special handle on the LENS, which should be taken care of when making plastic molds. Strengthen different plastics and use different potions. After the strengthened LENS, the surface printing also uses a special process to ensure adhesion.

Coating: For lens decoration, there will be some coating on the lens. Common vacuum coater coating methods include sputter coating and evaporation coating. Evaporative coatings have a shorter production cycle. However, compared with the evaporation coating, the coating layer of the sputter coating has a strong bonding force with the substrate, and the coating layer is dense and uniform. Common splashing effects are silver, bright silver, gold, gun color and other metallic colors. In addition, it can also be sputtered into a semi-transparent effect, which is a transparent lens when the backlight of the mobile phone screen is turned on. When the backlight is turned off, the phone screen turns into a mirror. Optical coating: The optical coating is alternately plated with SiO2 and TiO2 on the workpiece, and the thickness of the coating and the number of coating layers are controlled.
