Vacuum evaporation is a technique in which the target material of the plating material is heated and evaporated under vacuum conditions, causing a large number of atoms and molecules to vaporize and leave the liquid plating material or the solid plating material surface (or sublimation), and ultimately deposit on the substrate surface. Throughout the process, gaseous atoms and molecules will undergo minimal collisions in vacuum and directly migrate to the substrate, depositing on the surface of the substrate to form a thin film. The methods of evaporation include resistance heating, high-frequency induction heating, electron beam, laser beam, ion beam high-energy bombardment of the plating material, etc.

The DLC (diamond-like carbon) coating developed by Aoshi has a leading position in the industry, and the coating meets the needs of industrial production with stable performance.

DLC characteristics: It has extremely high hardness (Hv2000~Hv3800), excellent wear resistance, extremely low friction coefficient (as low as 0.06), strong adhesion with the substrate, excellent corrosion resistance, and can deposit on the surface of metal materials and some non-metallic materials

DLC applications: high-precision mirror molds, automotive parts, cutting tools for non-ferrous metals, graphite, acrylic, textile equipment accessories, plastic top pins, sliding parts, inserts, automation vulnerable parts, etc

PVD160 arc coating equipment (specialty: c-TA  st AC), PVD arc (multi arc) coating equipment (specialty: T  p-CR), PVD ion beam coating equipment (specialty: sl-C  p-TC)

PVD160 arc coating equipment (professional: c-TA  st AC) arc evaporation source adopts a variable pulse electromagnetic+permanent magnet design, which makes the arc spot finer, moves faster, covers a larger area, and has more arc spots, effectively suppressing liquid droplets. The equipment is equipped with gas ion etching technology, which can perform large-scale etching through powerful ion etching technology, and difficult to remove dirt in deep grooves through pre-treatment such as cleaning, improving coating adhesion and reducing product defects caused by low adhesion.

PVD arc (multi arc) coating equipment (professional: T  p-CR) has fast deposition speed, high ionization rate, large ion capacity, good film adhesion, simple equipment operation, low operating cost, and high production efficiency. This equipment is mainly used for direct coating on metal surfaces, combined with ion assisted functions. It can be used for direct surface bottoming and surface coating on metal films, nitride films, oxide films, and other composite films. The patented arc cathode design makes the film have smooth surface, high hardness, friction resistance, and dense film layers.

PVD ion beam coating equipment (professional: sl-C  p-TC) is mainly used for depositing wear-resistant and lubricating coatings on the surface of molds, cutting tools, cars, sewing machines and other spare parts. The surface hardness of coated products can be greatly improved, reaching 2000HV or above, and has an extremely low friction coefficient (0.1-0.2), significantly reducing scratches and friction generated during processing and greatly improving product quality; Low temperature coating film-forming technology can prepare both metallic and non-metallic film layers.
