Arc ion vacuum coating machine coating device

                   

Vacuum coating machine multi-arc ion plating equipment, cold cathode vacuum arc discharge as a principle of multi-arc ion plating technique, as film-forming fast, low energy consumption; precise control of film thickness, composition ratio, etc., have become PVD one of the main deposition method art.

Obtained in the preparation of domestic and superhard film and decorative film in wide range of applications, coating device specification more arc evaporation source to the destination number is concerned, there are three sources, six sources of the source 4, 8 a source, the source 10, source 12, 16 sources, all sources 20, 26 sources, ......, 54 sources; in terms of the size of the vacuum chamber, there ф800mm x 800mm, ф1000mm x lOOOmm, ф1000mm x 1500mm.ф1250mm x 1800mm.ф1810mm x 3500mm.ф2200mm x 5000mm and so on

Below 1250mm x 2500mm x (0.6 ~ 2.5) mm steel plate as the base prepared from large decorative film coating machine, for example, tell us about the structural characteristics of multi-arc ion plating equipment, working principle and operating procedures.

Coating device structure which is made part of the vacuum coating chamber, vacuum systems, pneumatic systems, electrical systems and other components. Annular region where the coating chamber is formed by a combination of inside and outside the cylinder through the superstructure and chassis made of. Indoor include revolves workpiece turret, an infrared heater heating the steel sheet, and 36 arc evaporation source distribution in the radial simplified. Is the number of arc evaporation source according to the cylinder diameter and height, and the uniformity of the film thickness of the gap and the spiral lines arranged. In order to prevent the upper and lower ends of the plated steel produce color on the upper and lower ends of the arc evaporation source were smaller pitch and tilt adjustments. Accordingly, the number of inside and outside the arc evaporation source 16 were simplified and 20.

Our research and development of multi-arc ion coating machine, also known as arc ion coating machine is an efficient, non-polluting ion vacuum coating machine, with deposition speed, ionization rate, ion energy, the equipment is simple, low cost, production large advantages. Arc ion plating is widely used tool, die superhard coatings, automobile wheels, golf equipment, watches, hotel supplies, sanitary ware, lamps, glasses frames, metal products, ceramics, and glass and other decorative coatings and other fields . Our efforts to improve the circular arc evaporation source, while efforts to develop high-performance flat rectangular arc evaporation source, are already equipped with the new machine.

Vacuum coating machine door and window hardware accessories bodyguard

   

Aluminum alloy doors and windows in the application of the most widely used, vacuum plating makes use of hardware accessories and decorative features to reach double effect.

Modern building windows and doors can be divided according to the profile varieties: plastic windows, composite windows, aluminum windows, aluminum windows which is now China's major building windows and doors products, accounting for a large proportion of today's buildings. In fact in terms of wind pressure, water tightness, air tightness and other properties or from the environmental aspects, aluminum window has its advantages.

Aluminum doors and hardware accessories is an important part of its performance and the quality of the doors and windows of the functioning of an important influence. Due to the continuous development of modern technology, the door and window hardware accessories (handles, handrails, sliding support hinges, slides, connectors, etc.), but also more and more into the market.

Because aluminum under natural conditions extremely passive features, hardware selection of general metal material, aluminum doors and windows will be a combination of a large structure in the form of small anode cathode.

The introduction of new technologies, new processes, new materials to improve the corrosion resistance of door and window hardware accessories only way. Foreign hardware manufacturers using physical vapor plating (referred PVD, also known as vacuum plating) produced excellent appearance and corrosion resistance metal parts. Vacuum plating with strong adhesion, coating easy to fall off; diffraction good, uniform coating thickness; dense coating, less needle larvae L bubble; tractable before plating process is simple; material saving, pollution and other advantages. Available on metal or non-metal surface coating system, alloys or compounds. Has been widely used in aviation, aerospace, electronics, and optics and other industrial sectors in the preparation of various special properties of the coating.

With the constant improvement of vacuum coating equipment, large-scale and continuous, and the development of paint coating technology, available with good adhesion, wear resistance, high brightness decorative coating. Abroad in some parts surface handle, hinges, etc., using vacuum plating Au, Ag, Al, Zr, TiN, lCrl8Ni9 etc., and get excellent overall performance of the outer surface, so handle, hinges, etc. These single functional accessories into a use double performance functional and decorative accessories.

The film vacuum coating machine control system

                 

Vacuum coating machines currently used to monitor the way the film is more, there are: visual monitoring method, fixed (extremes) value monitoring, crystal oscillation monitoring, time monitoring and so on. I mainly introduces visual surveillance, fixed (extremes) monitoring and crystal oscillation monitoring three.

Also called direct visual monitoring of the monitoring, the monitoring is to use the eye, since the film in the growth process, the color change will be due to the interference phenomenon, we are controlled according to the color change of the film thickness, there are some errors in this way, so it is not very accurate, need to rely on experience.

Electrical control part adopts PLC automatic control, is to enter the pre-designed in the PLC program, the processor main circuit with Kongshi system on the control panel is connected, when you press the switch on the front panel operation, the transmission of information to the central processor, and then by the central control system analysis and issue commands to execute and complete the action by the branch.

Coating machine is a multi-discipline device, which integrates industry today's most advanced mechanical and electrical technology, control technology, electrical automation, IT technology, refrigeration technology, micro-circuitry integrated systems, high-pressure control systems, mechanical technology, processing technology, optical technology optical technology, pneumatic control technology, optical sensor technology, communications technology, vacuum technology, thin film optics and coating technologies.

It can be said coater is a new industry representatives.

Today, coating machines have been widely used, especially film-plated wide variety of film which is applied to the production of various photovoltaic systems and optical instruments, such as digital cameras, digital cameras, binoculars, projectors, energy control, optical communications display technology, interferometer, satellite missile, the semiconductor laser, micro-electromechanical systems, information industry, laser production, various filters, industrial lighting, sensors, architectural glass, automotive, decorations, coins, glasses, etc. etc., coating machine has been in close contact with human life.
