In my opinion, a few years ago, Shanghai Electric Group sold Shanghai Guanghua, Shanghai Yahua, Shanghai Shenweida and Shanghai Ziguang in its printing and packaging machinery group. This incident is a "black swan event" in the Chinese printing machine manufacturing industry. The "black swan event" refers to an extremely unpredictable and unusual event that often causes negative reaction or even subversion of the market chain. This article will introduce you to the manufacture of printing machinery.
At present, the evaluation of energy saving and environmental protection of printing machinery mainly adopts two methods: one is calculated according to the type of energy consumption of printing machinery, and the other is calculated according to the process of energy consumption of printing machinery. The indicators used for calculation are usually the energy saving of the printing machine, the energy saving rate of the printing machine, the energy consumed comprehensively, the equivalent value of the energy consumption of the printing machine, and the like.
However, many experts disagree with this method. They believe that these methods are too thin for the energy consumed by printing machinery. They include not only the process of consuming energy, but also the consumption of various resources, complicating the problem, and operating. The performance is poor, and the measurement of various consumptions does not have a complete testing method, and it is difficult to obtain data.
Because of the complexity of the printing machinery structure, due to many factors that determine the energy consumption of printing machinery, such as the structure of the machine, the processing and assembly accuracy of the parts, the control method, etc., we can not accurately analyze these factors.
In summary, the unit energy consumption, comprehensive energy consumption, energy conservation evaluation value, and user increase investment recovery period can be selected as energy-saving evaluation indicators for printing machinery products.
In order to grasp the types of energy consumed by printing machinery, printing machinery has released some methods for environmental protection and energy saving evaluation of printing machinery. It is understood that only flexographic printing machines, gravure printing machines and composite printing machines use gas for heating. Other models They all use electricity for production. In order to simplify the complicated problems, the energy consumption of various types of printing machinery is divided into two types of energy consumption: single energy consumption and two or more energy consumption.
China's urbanization and urbanization are surging, which will inevitably lead to a large demand for printing and packaging. Looking forward to the future, the author is daring to predict that it will continue to develop according to the current trend, and the fastest printing of Chinese printing in India and China will be carried out in 5 to 10 years. Equipment manufacturing (focus on offset printing), the whole will no longer exist
