Decorative pvd coating machines are often used in the decoration industry, such as hardware accessories, stainless steel, glass, crystal, ceramic tiles, ceramics, plastic items, etc. are coated with a thin film layer by the decorative vacuum coating machine, not only for the product The appearance looks more beautiful, and it also changes the performance and life of the product. And because the decorative vacuum coating machine is coated in a vacuum chamber, it has the effect of no pollution and green environmental protection. Therefore, it has been favored by many coating processing manufacturers. So when choosing a decorative pvd coating machine, what purchase points should be considered? The following is a collection of vacuum editors to sort out the main points for your reference:

Purchase points of decorative pvd coating machine:
       1. The furnace body can choose a double-layer water-cooled structure made of stainless steel, carbon steel or their combination.
       2. According to the process requirements, choose different specifications and types of coating equipment, such as resistance evaporation, electron beam evaporation, magnetron sputtering, magnetron reactive sputtering, ion plating, hollow cathode ion plating, multi-arc ion plating, etc.
       3. The operation forms of the fixture include rotation, revolution and revolution + rotation. Users can put forward corresponding requirements according to the size and shape of the substrate. The rotation speed range and rotation accuracy: ordinary adjustable and variable frequency speed regulation.
       4. The vacuum system consists of mechanical pump, diffusion pump, oil booster pump, augmentation pump, Roots pump, crucible wheel molecular pump, etc. and various pneumatic, manual, electric valves, pipelines, etc. that match them.
       5. Select the plating method and form according to the process requirements, such as resistance evaporation (tungsten wire, molybdenum boat, graphite boat) magnetron source (coaxial cylindrical magnetron source, cylindrical plane magnetron source, rectangular plane magnetron source Source, etc.) with target material and size multi-arc source (Ф60, Ф80 diameter target, pneumatic, electric arc ignition, etc.), vacuum measurement can choose digital intelligent vacuum gauge and its high-quality measuring gauge, and other measuring instruments , such as automatic pressure controller and so on. The film thickness measurement can choose a square resistance measuring instrument, a transmittance meter, etc.
       6. Mass flowmeter, float flowmeter + needle valve and corresponding inflation valve can be selected for the inflation method, and multi-channel inflation pipelines and corresponding flow parameters can be selected.
       7. According to the structure to be baked, propose the baking temperature, material and the corresponding instrument measurement required.
       8. According to the use characteristics of the decorative pvd coating machine, manual, semi-automatic, fully automatic or a combination of control methods can be selected.
       9. Perfect alarm system, sound and light alarm for abnormal situations such as vacuum chamber body, diffusion pump phase failure, water shortage, air pressure, overvoltage and overcurrent of power load.
