The plug leakage of the ion vacuum coating machine
The method of Ion vacuum coating machine for leak rate measurement is to cover the entire suspicious area of the inspected part with the leaking gas (leaking substance), or to fill the leaking substance in the inspected part, and the other side is atmospheric pressure environment or Vacuum, or form the concentration difference or pressure difference of the leaking substance on the inner and outer sides of the tested part, and measure the leakage rate and concentration change of the leaking substance on the low concentration or low pressure side.
In recent years, the vacuum coating equipment industry has continued to develop, and the technology has been updated day by day, allowing more business friends to get rid of the traditional primitive coating methods and methods. Whether it is the comparison between the entire industry and the same industry abroad, or the comparison within the industry, it has exposed some problems and gaps in the vacuum coating industry.
1. Product research and development capabilities: It can be said that there is basically no capital input or only a small amount of capital investment. The research and development capabilities are poor. Most of them are taking orders while walking, designing and producing. So To some extent, it caused the unreliability and instability of the coating equipment and the immaturity of the process.
2. The technology needs to be upgraded. Although some companies have improved due to relocation in recent years, the manufacturing costs, the level of technology, and the level of inspection are still relatively backward, and they are not comparable to those of foreign vacuum coating equipment counterparts. In contrast, the technical transformation problems left over from the old system may be difficult to eliminate in the short term. The obsolete equipment, the backward technology and the low product level, are problems that almost every enterprise in the industry has.
3. The problem of the management mechanism model: The current Chinese family style or the share-holding cooperation style between friends reflects the outdated management concept. The disadvantages of the development model machine cannot promote the development of the vacuum coating equipment industry, even if it is now Enterprises that have been reformed by the shareholding system, or those that have obtained advanced management in China's machinery industry, still lag far behind Western developed countries in management.
4. The problem of professionals: This is a common problem common to the entire machinery industry or the entire Chinese enterprise. High-quality pioneering technicians, skilled craftsmen, and white-collar workers with unique management are severely lacking in enterprises. In enterprises, technical personnel and skilled workers are indispensable. Of course, with the passage of time, the problem of talent will have a good turn.
