PVD decorative coating machine combined with newest coating technology

Product Description

Vacuum magnetron sputtering coating machine are widely used in household appliances, clocks, lamps, crafts, toys, light reflectors, cell phone buttons shell and instruments and meters, plastic, glass, ceramic, tile and other decorative coating surface and the function of the mould coating.The so-called "splash" can be in the charge particle bombardment objects (usually use gas positive ions), causing surface phenomenon of atoms to escape from the mother, as early as 1982 Grove in the lab, discovered this phenomenon.

Magnetron sputtering target using static electromagnetic field, the magnetic field for the curved shape, uniform electric field and the logarithmic electric field is used for planar target and coaxial cylindrical target respectively.Electronic under the effect of electric field, the speed to fly to the substrate and argon atoms collide in the process, if the electron has enough energy (about 30 ev), the ionization Ar + and produce electronic, electronic flew to substrate, Ar + under the effect of electric field, the speed to fly to the cathode (sputtering target) and the high-energy bombarding target surface, make the sputtering target material.

Arc coating technology is characterized by:
• High deposition rates (~1-3 µm/h)
• High ionization, resulting in good adhesion and dense coatings
• As the target is cooled, little heat to the substrate is generated, i.e. even coating at temperatures below 100°C is possible
• Several compositions of metals can be evaporated, leaving the remaining solid target unchanged in its composition
• The cathodes can be placed in any position (horizontal, vertical, upside down), which makes flexible machine design possible

The main disadvantages of arc coating technology are:
• Limited kind of target materials - metals only (no oxides) - which do not have a too low evaporation temperature
• Due to the high current densities some amount of the target material is ejected as small liquid droplets

Combined with magnetron sputtering technology, it can coating multilayer films. Applies to hardware tool, glass crafts, ceramic crafts etc. such as watches, metal outer covering, sanitary ware, mold, electronic products, crystal glass, eyeglass frame, tableware, knives and so on. In recent years, electric arc ion coating technology has been greatly developed, from the original single arc source to the column arc and large flat arc etc. Combined with the technology of intermediate frequency(IF) magnetron sputtering makes it more popular.
