Plastic machinery is one of the fast-growing industries in the traditional machinery manufacturing industry, and the annual demand is also increasing gradually. The main reasons for the rapid development of plastic machinery industry are as follows:
1, the rapid development of plastic processing industry makes the demand for plastic machinery more vigorous.
2. The demand for high-tech molding machines has brought equipment renewal and elimination of backward equipment, and also promoted the upgrading and rapid development of molding machine industry.
Second, the development trend and direction analysis of plastic machinery
The demand for plastic products has promoted the development of plastic machinery. With the development of the molding machine industry itself, the future plastic machinery will mainly show the trend of combined structure, specialization, serialization, standardization, compounding, miniaturization, large-scale, personalization and intelligence, which generally has three directions:
1, development of mainframe and microcomputer
The types and specifications of small and medium-sized plastic machinery in China are relatively complete, but the mainframe and microcomputer are still in the initial stage. The design and manufacture of large and micro plastic machinery is closely related to the overall mechanical manufacturing and material technology level of the country, and attention should be paid to the establishment of relevant technical foundation and intellectual property system in the initial stage. Miniaturization is an important development direction of all kinds of products in the future, and more and more market demand is reflected in the obvious development momentum of electronics, information, electrical appliances, medical care, biology and other departments. For example, some countries have been developing plastic pipe production equipment with a diameter less than 0.5 mm to replace human blood vessels.
2. Development of energy-saving plastic machinery
Traditional plastic machinery still has some potential in energy saving, because the previous design often only focused on the production capacity of a single machine, ignoring energy saving. In the design of energy-saving plastic machinery, the production speed is not the most important index, but the most important index is the energy consumption of processing unit weight products. Therefore, it is necessary to optimize the mechanical structure, control mode and operating process conditions of the equipment with the minimum energy consumption as the goal. Due to the adoption of advanced energy-saving technology, the electric energy conversion efficiency of variable frequency motor is obviously higher than that of electromagnetic speed regulating motor and DC motor. With the maturity of variable frequency speed regulation technology and the reduction of its cost, it has been widely used in plastic machinery, especially in extrusion equipment.
3. Development of automatic and intelligent plastic machinery.
Automation and intelligence are the general trend of mechanical equipment development, and plastic machinery is no exception. The development of intelligent plastic molding machine will obviously improve the stability and reliability of plastic molding machine, effectively improve the production function of plastic molding machine with high quality, high efficiency and low consumption, and provide a solid technical foundation for realizing unmanned workshop and unmanned factory.
