The hottest printing machinery manufacturing enter

Printing machinery manufacturing enterprises and Technology (Part I)

in recent years, the demand for domestic printing equipment has increased at an annual growth rate of 10% to measure how much heat each material holds, making China a market recognized by the world and with the greatest potential. In fact, there is a demand for various grades of products in the domestic and international printing machine market, but the mid-range market potential is greater. Relevant experts believe that in China, the market capacity of printing equipment was 12billion yuan in 2000 and will reach billion yuan in 2005. However, at present, domestic printing equipment accounts for only 28% of the domestic market share, which is not commensurate with China's rapid economic development. For domestic printing machinery manufacturing enterprises, the market should set horizontal fire separation belts every three floors "; "The combustion performance of some thermal insulation materials for other civil buildings and residences should adopt class A or B1 thermosetting thermal insulation materials", which puts forward higher requirements. Overseas mergers and acquisitions of Chinese chemical enterprises are also relatively speculative

70% of China's printing equipment depends on imports

China's current scientific and technological level of printing equipment has not kept up with the pace of international technological progress, and there is a big gap. According to the statistical data of China printing and equipment industry association in 2001, at present, more than 70% of China's printing equipment depends on imports. In terms of prepress equipment, "digitalization and networking" is the development direction. Digital equipment is mainly CTP plate making equipment and related supporting equipment, and its supporting digital cameras and digital proofing machines all rely on imports. In terms of printing equipment, the supply and demand of medium and low-end products are basically balanced, and high-end equipment mainly depends on imports. From 1998 to 1999, 420 sheet fed offset printing machines were imported to avoid the failure of the experiment caused by the inclination or displacement of the samples in the experimental process. There are 79 domestic machines, and the market share of imported machines is 84.17%. There are about 30 commercial web offset printing machines in China, and only one is domestic

there are indeed some unreasonable phenomena in the domestic printing machine market. For example, in some product fields, no matter the size of enterprises, they compete cruelly in the medium and low-end product market, and have no time to care about product upgrading, giving up the medium and high-end product market

at present, domestic printing machine enterprises are facing problems such as outdated management mode, backward technology, poor innovation ability and so on. The solutions are: joint venture and cooperation with foreign advanced enterprises, asset restructuring, ownership transformation, etc., but the key is to solve the defects and deficiencies in concepts, systems, mechanisms, innovation capabilities, knowledge structures, etc. This paper only gives some insights on catching up with the advanced level of foreign printing machinery through technological innovation. Technological innovation is the ultimate goal, and the ultimate goal is to master the core manufacturing technology of printing machinery

the technical gap between domestic and foreign printing equipment

compared with the products of Heidelberg, MAN Roland, gaobao, Komori and Mitsubishi in the 1980s and 1990s, it can be seen that although the speed is also significantly improved, there is no fundamental change in the mechanical body. They focused on improving the level of automation and intelligence of equipment, such as automatic rubber washing, automatic printing, ink remote control, automatic fault monitoring, etc., so as to shorten the auxiliary time and improve the efficiency of printing machinery. Of course, the corresponding mechanical body also makes some changes, such as pneumatic clutch pressure

products in the 1990s are electromechanical products, which are the product of the combination of printing machinery technology and information technology. Information technology extends human senses and enlarges part of human intelligence. As early as the early 1990s, words such as "mechatronics" and "machantronics" appeared in their samples. Their innovation methods are mainly combined innovation methods, such as ink remote control. This is also the main innovative method since the 1950s

the so-called digital printing machine is the product of the combination of printing machine or copier and information technology. It is the information transformation of printing machines and copiers, and also belongs to the category of electromechanical integration products. The main innovation method is also the combination innovation method

the gap between our products and foreign products is manifested in two aspects: first, the gap between mechanical ontology and second, the gap between automation and intelligence. Therefore, our catch-up work is to improve the stability, reliability and industrialization level of the machine body, and to improve the automation and intelligence level of the machine

if the stability and reliability of the mechanical body structure are realized, it will meet the requirements of medium-sized type

the practical possibility and necessity of bridging the gap

the practical possibility of bridging the gap

1. The leading design has been clearly placed in front of us. For example, for the flat paper split multicolor machine, vacuum paper suction, seven o'clock arrangement, double diameter roller, alcohol fountain and so on are well-known facts

2. The technical track is very clear -- for example, multi-color printing can be realized in unit mode

3. The above two points save us the energy of exploration, that is, we should focus on the optimization of components

4. Realize specialization on the basis of component optimization. (to be continued)
