Vacuum forming machine is a simplified version of thermoforming, where a sheet of plastic is heated to a forming temperature, stretched onto a single-surface mold, and forced against the mold by a vacuum. This process can be used to form plastic into permanent objects such as turnpike signs and protective covers. Normally draft angles are present in the design of the mold (a recommended minimum of 3°) to ease removal of the formed plastic part from the mold.

This has pointed out the direction for the development of my internal precision industry. At present, the independent development capability of China's measurement technology and instruments is not strong, and the manufacturing technology is relatively backward. It is difficult to adapt to the fierce competition faced after joining the 10th. It can be seen from this exhibition that although China's geometric precision measurement technology and instruments have made great progress in recent years, on the whole, the gap with foreign advanced levels is not narrowing but increasing; The development of the number screwing technology and the number of screwing machine tools is very rapid. The current situation of unbalanced development has affected the overall improvement of China's manufacturing industry. This question should be brought to the attention and attention of the national authorities.
From this exhibition, the gap between the metering industry and the outside is mainly due to the aging of the product structure in the following aspects, and the development of product specifications for many years is slow. With the rapid development of machine optoelectronic computer technology, many technologies and products introduced or jointly developed by domestic enterprises in the late 1990s and early 1990s have lagged behind gear measuring instruments; some product renewal projects have been introduced after trial production, due to lack of funds. Or the market is changing and the production is stopped. Some machine tool factories are difficult to mass-produce, such as photoelectric laser measurement systems, due to technical funds. The most prominent question is the lack of independent innovation and specialty products. Due to the technical difficulty of the measuring instrument, especially the large-scale precision measuring instrument, especially the development and maintenance of measuring special hardware and software, the investment in the early stage is more than the market demand, and the investment is slow. Therefore, in recent years, many professional measuring instrument manufacturers have difficulty in operating, and some have been forced. Conversion. The domestic measuring instrument market faces the difficult situation of having money to buy abroad and not buying less money.
The integration and integration of measurement processing is the development trend of modern manufacturing technology. Only the traditional concept of developing production machine and neglecting measurement technology needs to be updated. If we do not formulate and implement strategies to implement balanced development of testing techniques and instruments. I am in the manufacturing industry to achieve a new technology. The National Relations Department should give full consideration to this.
In recent years, the domestic measuring instrument industry has carried out many useful explorations and practices on how to improve the overall level and innovation capability of China's measurement technology R&D and manufacturing, and shorten the gap with developed countries, and has made encouraging progress in some aspects. Edward's survey and set-up bath is a rookie in China's precision brother industry. The growth and development of the company is characterized by the advanced research results of the coordinate measuring machine technology brought back from overseas by the scientific and technical personnel studying abroad, and the domestic high-tech professional talent team is absorbed. At the same time, the competent departments at all levels also give encouragement policies and financial support. Because the company has the key technology coordinate coordinate measuring machine of the coordinate measuring machine, the construction and production technology. The method of establishing the mathematical model of coordinate measurement 1. The control technology of the bus under the 0 and the digital camera measurement technology including the computer image processing technology and the market competitiveness, with strong vitality and development space. This small and specialized enterprise has played a good role in the development of China's measuring instrument industry. The state should encourage such enterprises 303 Research Institute is currently the largest CMM development and production company in China. Perseverance continues to develop.

After years of hard work, Harbin Measuring and Cutting Tool Factory has developed its own independent development and cooperation with relevant universities. The performance and appearance of the instrument are becoming more and more mature. However, compared with similar foreign products, there is still a gap in the measurement software function. . The development path of combining the internal and external industries combined with the institutions and institutions of the above-mentioned enterprises is an effective measure to alleviate the weak basic technology research of the company's technical personnel, and is also an effective way to enable the enterprise to continue to develop. The original Qingdao Outpost Measurement Technology Co., Ltd. Joint venture with the United States 813 Company 建1 established the Qingdao Outpost Langpu Measurement Technology Co., Ltd., making full use of foreign advanced technology and management experience, and established a new development platform for participating in international competition after joining China.
