vacuum coating machine


The main component of the shell material of the vacuum coating equipment is metal. At present, metal vacuum shell materials mainly include metals and alloys based on Al, Cu, and Fe. Such as: stainless steel, carbon steel, red copper, oxygen-free copper, aluminum, copper, aluminum, nickel steel or iron. Among them, stainless steel, which has the advantages of corrosion resistance and low out-gassing rate, is an excellent material commonly used in vacuum coating machine housings. In addition, due to the low diffusion rate of hydrogen in aluminum, the material has a low out-gassing rate after baking. Therefore, this type of material is also the main material for the casing of ultra-high vacuum equipment that is expected to be further developed.








At present, vacuum coating machines are used in optics, glasses, plastic films, metals, lamps, ceramics, glass, cheap plastics, ceramics, and various plastic toys, plastic daily decorations, artificial jewelry, Christmas decorations, home appliances decoration, electrical appliances The surface of the instrument is metallized and coated, and the vacuum coating machine is widely used.


The customers we meet often have such confusion. After the demand for the coating layer of the product is large, they know what material their products need to be plated, and they also know that a layer of film should be coated on the material, but domestic and foreign coating machine manufacturers There are too many coating machines that have a major impact on the processing of the entire product and need to be purchased. However, I don't know what vacuum coating machine to purchase, and I don't know how to purchase a vacuum coating machine suitable for my company. So, how to choose a suitable brand coating machine?


  The recommendations given by the experts are as follows:


  1. Choose the type of vacuum coating machine according to the material of the workpiece to be coated and the effect of the coating. For example, if you are mainly engaged in high-quality processing, then we have to buy a vacuum aluminizing mirror machine; if you are engaged in plastic coating, such as the automotive lampshade industry, then we have to choose a circular vertical vacuum coating machine.


  2. Various process parameters that can be achieved by the vacuum coating machine should be considered, such as coating color, roughness, adhesion, etc.


  3. The power conditions of the equipment must be considered, and the power consumption must be considered according to the configuration. Otherwise, the power problem will not be solved, and the equipment will not be usable if it is bought back.


  4. The production capacity and quality of vacuum coating should be considered to choose a suitable vacuum coating machine. If the selection is small, the output cannot keep up. If the selection is large, the price will be high on the one hand, and the excess capacity on the other hand will cause waste of resources. And too much equipment is not suitable for all products.


  5. For site issues, it is necessary to buy a vacuum coating machine of what size as required to consider how much area is needed to install the equipment.


   6. Does the technology of the vacuum coating machine manufacturer support it? Is there a repair service? When purchasing, let the vacuum coating machine manufacturer recommend the factory that has purchased the coating machine, and ask about the quality of the coating machine manufacturer's coating machine and how is the service?


7. The characteristics of high-end equipment, equipment stability must be good, and the selected accessories must be reliable. The coating machine itself is a complex system, including vacuum, automation, machinery and other systems. The unreliability of any component will cause The instability of the system will bring inconvenience to production. Therefore, a stable equipment must ensure that every component selected is reliable. Many people will naturally compare when buying a coating machine. The basic configuration of the coating machine and a 2 million coating machine may not be very different, but it is the mastery of some tiny details that makes a stable performance coating machine, a simple sentence :you get what you pay for.


8. Look at which company's coating machine is selected by well-known companies in the same industry. This is undoubtedly a choice with low risk. In addition to well-known companies, there are also some small and medium-sized companies with very stable quality and good reputation. Through friends, find out which company’s equipment they are using. If you want to compete with these companies, choose a coater that is at least not worse than him. This is basic, and then hire an experienced coater to make your product. Will soon open the market.


9. At present, there are basically two types of vacuum pumping systems, one is a diffusion pump system and the other is a molecular pump system. The molecular pump system is a clean pumping system without the oil return phenomenon of the diffusion pump, and the pumping speed is relatively stable. Moreover, it is relatively power-saving, and the expenditure of electricity is a large part of the production and operation costs of coating enterprises. The regular maintenance of the pump system is very important, especially the regular replacement of the lubricating oil. Pay attention to the choice of the oil brand. The wrong choice can easily damage the vacuum pump.


10. The vacuum detection system currently basically uses a combination of composite vacuum gauges, thermocouple gauges + ionization gauges. When this combination encounters a process of filling a large amount of gas containing C element, the ionization gauge is easily poisoned and damages the ionization gauge. If the process of plating a gas containing a large amount of C element, you can consider configuring a capacitor film gauge.


11. Vacuum power supply, the gap between domestic power supply and imported power supply is quite obvious. Of course, the price is relatively favorable. A domestic 20KW intermediate frequency power supply is about 80,000, and an imported intermediate frequency power supply is 200,000. The performance and reliability of the imported power supply Performance and stability will be better. Domestic power supplies may be better in service than imported power supplies because they are produced in China.


12. Control system. Now many vacuum coating machines adopt fully automatic control, but the difference in automatic control is still very big. Most of them are still in semi-automatic state, which can truly realize fully automatic control and one-button operation. There are not many coating equipments, and whether to provide sufficient safety interlocks during operation in automatic control, the functional modules are also very different.


13. Do you need to configure a low-temperature trap PolyCold? The low-temperature trap can be said to be an icing on the cake. It can greatly increase the speed of air extraction, adsorb the condensable gas in the vacuum chamber on the cold coil, and purify the vacuum The indoor atmosphere makes the quality of the film better. In the hot and humid summer, the use of low temperature traps undoubtedly improves the production efficiency to a large extent.


   For customers, what they need is not a low-priced product, but a trade-off between brand and price, and choose a brand that can meet their needs and meet their budget. When customers are faced with the choice of many suppliers due to specific needs, more and more customers tend to choose an influential brand or a brand that has been deeply cultivated in the industry for many years.

In many vacuum equipment, there are two commonly used materials for the shell, its metal and glass. In contrast, metal vacuum equipment has the advantages of better mechanical strength and easy to achieve high-precision processing; while glass equipment has the characteristics of transparency and electrical insulation, making the internal conditions of the equipment easier to observe, The high-frequency heating method can be used to degas the metal parts inside the equipment. In addition, the high-frequency spark gun can be used for leak detection and easy processing. However, because glass has the characteristics of brittle and fragile material, the shell of vacuum coating machine mostly uses metal as the main construction material, and glass is often used as the main material of the observation window.
The main component of the shell material of the vacuum coating equipment is metal. At present, metal vacuum shell materials mainly include metals and alloys based on Al, Cu, and Fe. Such as: stainless steel, carbon steel, red copper, oxygen-free copper, aluminum, copper, aluminum, nickel steel or iron. Among them, stainless steel, which has the advantages of corrosion resistance and low out-gassing rate, is an excellent material commonly used in vacuum coating machine housings. In addition, due to the low diffusion rate of hydrogen in aluminum, the material has a low out-gassing rate after baking. Therefore, this type of material is also the main material for the casing of ultra-high vacuum equipment that is expected to be further developed.
