The annual growth rate of China's plastics machinery industry in recent years is about 30%, which is one of the fastest growing industries in China's machinery industry. As the largest variety of injection molding machine, the annual output accounts for about 35% of the total output of the presses and accounts for about 60.4% of the total volume of exported presses in the country. With the increasingly fierce competition in plastic products, energy-saving injection molding machine has become the mainstream market. "All-electric and two-plate injection molding machines are very energy-saving and consume less, are in line with national industrial policies, and have now become popular in foreign countries. I believe this is a development trend," said Wang Xingtian.
Compared with traditional hydraulic injection molding machines, all-electric injection molding machines are cleaner because they do not use hydraulic oil, which also means that there is no need for cooling, so there are no costs incurred for the purchase, operation, and maintenance of cooling lines, and at the same time, energy consumption can be reduced. Up to 30% to 50%, and stable operation, high repeatability, especially for precision injection molding. In Japan and European and American markets, all-electric injection molding machine technology has been used on a large scale. In the new domestic projects, the model has also been recognized as the focus of the development of presses. All-electric injection molding machine control system is very complex, the current leading domestic injection molding machine companies - Haitian Group has introduced such products to the market, filling the domestic gap.
At present, China's injection molding machines are still dominated by the three-plate type. In developed countries in Europe and America, the compact two-platen injection molding machine has become the mainstream of the market and has gained wider application in new construction projects. The two-platen machine has reduced one template compared to the three-platen machine, so the cost is lower, the opening and closing mode cycle is shorter, and the efficiency is higher. However, the structure of the piston in the cylinder of this type of engine is complicated, and the hydraulic valve cannot be installed when the piston of the fuel cylinder is small. Therefore, the medium and small-sized machines cannot be used, and they are generally applicable to larger models. Wang Xingtian pointed out: “Two-board machines are the main stream for the development of mainframes. Accelerating the development of these types of models is a topic that domestic companies should focus on.†The good news is that domestic companies such as Donghua and Haitian have been developing and producing two-platen machines. , And some products have been successfully developed, which will bring China's large-scale injection molding machine design and manufacturing to a new level.
Different from Ultrasonic Heat Counters,The Smart Heat Meters are used for heat and cold energy calculation through the water. The smart Heat Meters can display the accumulated heat, flow rate, instant flow rate, inlet water temperature, outlet water temperature, temperature difference and etc.
The smart heat meter is suitable for measuring the heat exchange, known as the heat transfer fluid or liquid absorbing thermal energy conversion equipment, which consists of a flow sensor, temperature sensor and heat calculator(Heat Meter Counters) three parts. The smart heat meters are also known as smart energy meters.
The smart heat meter is used to measure and display the water flow through the heat exchange system release or absorb heat. The smart heat meters are installed at the inlet pipe or outlet pipe to measure accurate metering and intelligent control of charges of the heat consumption. Its working principle is to install the smart heat meters in the heat exchange system, when water flows through the system, according to the supply and return water flow temperature, from the data from the flow sensors and temperature sensor as well as the water flow time, the smart heat meter will calculate the released and absorbed energy through the calculator.
