With the continuous demand for market diversification, for many enterprises need to purchase different machines and equipment according to their product processes. For the vacuum coating industry, if a machine can be completed from pre-coating to post-coating processing, no manual intervention in the process without conversion, that is certainly what enterprises want. In a single machine to achieve the integration of multi-functional has become a common demand for coating equipment enterprises.
Vacuum coating equipment is commonly used in industrial production, whether small or large products, metal or plastic products, or ceramics, chips, circuit boards, glass and other products, basically all of those need to be surface process coating before using. In the coating method, it is more common to use evaporation coating, magnetron sputtering coating or ion coating, and in the control technology, more advanced computer technology and microelectronics technology are applied, making the vacuum coating equipment more efficient and intelligent automation.
Since the reform and opening up, the vacuum coating industry has made great development and progress, which is not only reflected in the substantial growth of output value and production, but also in the varieties, specifications and comprehensive technical level. This shows the fact that the development and application of high technology has promoted and driven the development and technical upgrading of the vacuum equipment industry.
In the last decade, China’s vacuum coating equipment has been developing rapidly due to the large demand of enterprises. Various types of vacuum coating equipment with various coating processes are increasing and their functions are becoming more and more complete.
As far as the domestic situation is concerned, the past two years more attention to the vacuum coating industry people are mainly concentrated in East China, South China. Guangdong, Zhejiang and Jiangsu provinces are far ahead of other provinces in terms of vacuum coating concern. More than 5,000 domestic vacuum coating enterprises in which Guangdong and Zhejiang provinces have a total of more than 2,500, accounting for as much as 50% of the domestic vacuum coating industry which plays an extremely positive and important role in promoting.
At present, vacuum coating machine is applied to optics, glasses, plastic film, metal, lamps, ceramics, glass, cheap plastic, and various plastic toys, plastic daily decorations, artificial jewelry, Christmas decorations, household appliances decoration, electrical instrumentation surface metallization coating. Vacuum coating machine is very widely used.
Customers in the product coating layer demand is large, often know what their products need to be coated, and also know that need to coat a film layer on the material. But there are too many domestic and foreign coating machine manufacturers, coating machine for the whole product processing has a significant impact. Need to purchase vacuum coating machine, but do not know how to select a suitable one for their own company.
To this, professionals had given the following reference suggestions.
1, according to the material of being coated workpiece, and what kind of effect is coated to buy the type of vacuum coating machine. For example, if mainly engaged in hardware processing, then we have to buy multi-arc ion coating machine or magnetron sputtering coating machine. If engaged in plastic coating, for example, to do the car lamp cover industry, then we have to choose the lamp protection film coating equipment.
2, Need to consider the process parameters that can be achieved by the vacuum coating machine, such as coating color, roughness, adhesion, etc.
3, Need to consider the power conditions of the equipment, and how much electricity consumption based on the configuration, otherwise the power problems can not be solved, the equipment bought back can not be used.
4, Need to consider the capacity and quality to choose the right vacuum coating machine, choose a small machine can not keep up, while choose a large one, on the one hand, the price will be high, on the other hand, excess capacity resulting in a waste of resources. The equipment is too big, and not suitable for the production of all products.
5, Site issues, according to the requirements to buy how big specifications of the vacuum coating machine to determine how large an area is needed to install the equipment.
6、Is the technology of the vacuum coating machine manufacturer supported? Is there a maintenance service? When purchasing, it is better to let the vacuum coating machine manufacturers recommend the factory that has purchased the coating machine, to ask about the quality of this coating machine, and how is the service?
7, High-end equipment features. Stability of the equipment must be good, the accessories must be reliable. The coating machine is a complex system, including vacuum, automation, mechanical and other multiple systems, the unreliability of any one component will cause system instability, will bring inconvenience to the production. So a stable equipment need to ensure that the choice of each component is reliable. Many people purchasing a coating machine, will naturallly compare. A 1 million coating machine and a 2 million coating machine in the basic configuration may not be very different, but it is the mastery of some tiny details, to achieve a stable performance of the coating machine. the most simple words: you get what you pay for.
8, Knowing the industry’s well-known companies are using which company’s coating machine, which is undoubtedly the least risky way to choose. In addition to well-known companies, including some very stable quality, good reputation of small and medium-sized companies, through friends, to understand which company’s equipment they are using. If you want to compete with these companies, choose a coating machine that is at least not worse than his, and then hire experienced coating master, so that your products will quickly open the sales.
9、Vacuum pumping system, there are basically two kinds, one is the diffusion pump system, one is the molecular pump system. The molecular pump system belongs to the clean pumping system, no diffusion pump oil return phenomenon, pumping speed is also relatively stable, and relatively power saving, electricity expenditure is a big part of the production and operation cost to the coating enterprises. Regular maintenance of the pump system is very important, especially the regular replacement of lubricating oil, pay attention to the choice of oil brand number, the wrong choice is easy to damage the vacuum pump.
10、Vacuum detection system. At present, it is basically a composite vacuum gauge, thermocouple gauge + ionization gauge combination. This combination in the process of charging a large amount of gas containing element C, ionization gauge is easy to poison, resulting in damage to the ionization gauge. If the coating contains a large amount of gas of element C, you can choose the configuration of capacitive film gauge.
11, Vacuum power supply. Domestic power supply and imported power supply gap is still relatively obvious, of course, the price is more favorable, a domestic 20KW IF power supply in about 80,000, an imported IF power supply in 200,000. Imported power supply performance and reliability, stability will be better. Domestic power supply due to the origin in the country, may be better in service than imported power supply.
12, Control system. now many of the vacuum coating machine are fully automatic control, but the difference in automatic control is still very big. Most of them are still in a semi-automatic state, really can achieve fully automatic control, one-button operation of the coating equipment is not much. And in the automatic control whether to give enough safety interlock in the operation, the functional module is also a big difference.
13, Whether to configure low temperature trap PolyCold. Low temperature trap can be said to be a kind of icing on the cake, it can greatly improve the speed of pumping, the condensable gas in the vacuum chamber adsorbed on the cold coil, purify the atmosphere in the vacuum chamber, so that the quality of the film layer is better. In the hot and humid summer, the use of low temperature trap is undoubtedly to a large extent, improve the production efficiency.
For customers, what they need is not necessarily the lowest-priced product, but a trade-off between brand and price, choosing the brand that can meet their needs and fit their budget. When customers with a specific need are faced with a choice of suppliers, more and more of them tend to choose a brand that has influence or has been in the industry for many years.
