Plastic machinery plays an important role in the production of plastic. Since the 21st century, the plastic machinery industry has continued to develop rapidly. And it is one of the fastest developing industries with the main economic indicators top of the national machinery industry. At present our country has 546 domestic plastic machinery manufacturers, among which are mostly injection molding machine manufacturers. The largest 10 industries accounts for 39% of total sales in this industry. With extension technology and competitive price in the past five years, our manufacturer has established the enterprise successfully challenging Germany and Japan, Europe and the United States and other developed markets.
However, China is still an important importer of plastic machinery. Our country mainly produces low-end plastic machinery and lacks enough technologies of plastic machinery, which results in low plastic machinery export price and lack of international competitiveness. And the price of injection molding machine import is more than three times than that of domestic machine . The price of imported extruder and granulator has been more than 30 times. Thus many plastic machinery manufacturers will disappear in the low-end market in the next five years.
The fixed models and uniform specifications of the plastic machinery have not met the needs of market for many years. Plastic machinery industry provides the plastic machinery with market adaptability for customers, due to the customers،¯ requirements for the production of plastic products and consideration of effective investment in business. Meanwhile, with the rapid evolution of industrialization to the commercialization, it is unavoidable to appearance of mass production. Thus these five trends of plastic machinery can resist plastic machinery weeding out:
First, strengthen to develop precise injection molding machine and extruder
The precis
Second, the development of mainframe and minicomputer
Our country has small and medium-sized plastic machinery category and complete specifications with the infancy of mainframe and minicomputer. Large and miniature plastic machinery design and manufacture are closely related to national level of the overall mechanical manufacturing and material. China will pay attention to the related technical basis and to establish the system of intellectual property rights in the early stage. Miniaturization is an important trend of products. Such evidence is that market has increasing demand and obvious development in the electronic, information, electronics, medical, biological and other departments. Some countries, for example, are studying plastic pipe production to replace the human body blood with vessel diameter less than 0.5 mm.
Third, the development of energy-saving plastic machinery
Energy saving still exists in traditional plastic machinery , because previous design only focuses on the capacity of single machine production . In the design of energy-saving plastic machinery, the most important indicator is energy consumption of unit weight products, not the production speed. Therefore, the minimum energy consumption is needed in mechanical structure, control mode, and operating process. USES the advanced energy saving technology, variable frequency speed regulating motor power conversion efficiency is significantly higher than previously electromagnetic adjustable speed motor, dc motor, etc.. With the mature of frequency control technology and reducing cost of frequency conversion governor, all of them are widely adopted in plastic machinery, especially in extrusion equipment.
Fourth, the development of automation and intelligent molding machine
The development of the intelligent machines like automation and intellectualization will significantly improve the running stability and reliability, which benefits to producing function like high quality, high efficiency and low consumption and also offers solid technical foundation to realize unmanned workshop and no one factory .
Fifth, networking and virtualization
Network management technology can be seen as an extra technology, but it is really connected with equipment. From the auxiliary equipment plant to main engine plant, the network management system is seen as one of the control function provided by equipment. This will promote the international integration of design and manufacture on a higher level and implement more robust molding machine specialized production.
In recent years, the state ministry of industry and information technology has issued the equipment industry technical progress and technical innovation investment direction (2010) and other major strategic. This provides a rare and important opportunity to accelerate the development of Chinese plastic machinery industry. Plastic machinery enterprises should seize the opportunity to meet challenges so that plastic machinery plays a greater role in the process of the revitalization of the national economy.
