Research status at home and abroad
In the past ten years, the upgrading of international screen printing technology and equipment has exceeded people’s imagination. In 1999, the information at the European PESPA International Screen Printing Exhibition and the US SGIA International Screen Printing Exhibition showed that the color desktop typesetting system, the computer prepress processing system, and the electronic imaging technology have been widely used in the screen printing industry. Screen printing is developing in the fields of large-format screen printing and electrostatic printing. These high-tech developments and the demand for screen printing have brought great development opportunities to the screen printing machine industry. At present, China, South Korea, Japan, the United States and Western Europe and other countries vigorously develop the liquid crystal industry, a very important part of which is the screen printing of liquid crystal glass, which uses computer technology to achieve automatic control of screen printing machines. At the same time, the multi-color screen printing linkage machine has also been widely used in European screen printing enterprises.
In today’s world, the screen printing industry in Europe, America and Japan is relatively developed. Among them, the US screen printing industry developed rapidly in the late 1980s. 5,000 manufacturers were engaged in the screen printing industry, with an annual output value of about 3 billion US dollars, accounting for 10% of the total output value of the US printing industry. At present, the famous international brands of rotary screen platform type automatic screen printing machines include Japan Mino, Japan Sakurai, Japan Tokai Shoji, Italy SIAS, Germany SPS , Sweden Svecia (Svecia), Merbec of the United States, etc., especially the screen printing equipment produced in Germany, which are well-made and complete in variety, and enjoy a high reputation in the industry. The automatic rolling type screen printing machine has long led the trend of screen printing of the world’s high-precision screen printing machines. Since the 1980s, the development characteristics of the international screen printing industry: the proportion of screen printing in the entire printing industry is increasing. High; the field of screen printing applications is more and more extensive; screen printing technology is widely used in computer technology; screen printing machinery is developing towards automation, and materials are developing towards a variety of high-quality.
In the 1980s, my country’s flat screen printing equipment experienced a development process from simple to complex, from manual to fully automatic, from low-grade to high-grade, and screen printing technology has developed rapidly. At present, domestic equipment manufacturers have been able to Produces various specifications of screen printing equipment, some of which have reached the advanced level of foreign printing equipment.
There are strict requirements on the construction strength, stability and comprehensive accuracy of screen printing equipment. There are more than 200 manufacturers of screen printing machinery in China, and there are more than 50 manufacturers that have begun to take shape and have formed a certain production capacity, most of which are located in Beijing, Shanghai, Tianjin, Guangdong, Zhejiang, Jiangsu, Fujian, Hebei and other provinces and cities. .
Although the screen printing industry has made great progress in my country, the current screen printing industry still cannot meet the requirements of science and technology and the needs of the market. In terms of technology, there is still a certain gap between my country’s screen printing technology and developed countries’ screen printing technology, mainly in terms of equipment performance, dimensional accuracy, running speed, registration accuracy, and technical grades. Manual and semi-automatic types still account for a large proportion of
However, it has been unable to meet the requirements of economic and social development. At present, although my country has the ability to independently develop high-precision, automatic screen printing machines, there is still a certain gap with the United States, Japan, and South Korea. High-precision, automatic screen printing machines still need to be imported. Therefore, the development pressure of my country’s screen printing equipment industry is still very high, which requires the unremitting pursuit and exploration of people in the industry.
Although the domestic screen printing machine is not as high as the imported screen printing machine from the United States, Europe, Japan, South Korea, etc., with high precision and stable performance, it has attracted the attention of many manufacturers with its unique low price. Many similar products have domestic prices. It is also 81 lower than that of foreign countries. For example, Beijing Qingda Tianda Technology Co., Ltd. has independently developed multiple generations of automatic flat screen printing machines, including large-format screen printing machines, breaking the situation that my country’s screen printing equipment has long been dependent on foreign imports. The company produces
The fully automatic screen printing machine has the characteristics of high precision, stable performance, and high cost performance.
