Plastic Extruder Multi-functional Development
Plastic Extruder Multi-functional development
The multi-functional development of plastic extruder can expand its applicable space
In all kinds of plastic machinery, the core is undoubtedly a plastic extruder, plastic processing industry has become a widely used one of the models. Plastic extruder consists of extrusion system, transmission system and heating and cooling system, according to the number of screws can be divided into single screw extruder, twin screw extruder and multi-screw extruder. From the use of extruder to the present, the extruder developed rapidly and gradually formed a track in line with their own development.
Plastic Extruder modular specialized production on the one hand can strive for greater market share, on the other hand to ensure the quality of the whole period and speed up cash flow are very favorable, multi-functional development can expand its applicable space, large-scale development can be reduced Production costs, in the next development, we need to focus on its functional and network, while saving manpower to ensure the stability of the process, can greatly improve the accuracy of the product.
China's plastic extruder market is developing rapidly, there are many new models introduced by the industry's technology, R & D personnel to work together, some of the major special models such as exhaust extruder, tandem mill screw extruder, reciprocating Type screw extruder, foam extruder, extruder with melt gear pump, series multi-stage extruder, planetary screw extruder, etc. are produced in the domestic manufacturers, with the ability of independent research and development , And enjoy independent intellectual property rights.
With the upgrading of technology, plastic extruder equipment has long been the end of the manual feeding of the times, people can be heavy physical labor and dust flying in the environment freed, the original work done by the manual now by the transport equipment automatically The plastics industry has made great contributions.
Plastic extruder host and production line in the future market will be high technical content, the direction of price reduction. Domestic host is now basically tapered twin screw extruder and single screw extruder-based, more mature technology, the market is also the largest sales, but the general specifications of such products have been oversupply, can only maintain the peak market 50% to about 60%.
The future of the main focus of the host is the development of parallel to the twin screw extruder, suitable for large extrusion molding extrusion. Parallel to the same twin screw extruder to the sixth generation, the seventh generation of high-speed, large aspect ratio direction. Single screw extruder development direction is large diameter, large diameter ratio, exhaust smooth. In fact, the single-screw extruder is a low-power, low-cost model, as long as the technology properly, it is basically able to achieve the effectiveness of twin-screw extruder, such as the United States is now using plastic extruders are mostly Single screw, due to the high technological content, replaced the twin screw extruder.
Extrusion processing is one of the most important processing technologies in the plastics and rubber industry. Compared with the injection technology, extrusion processing with high efficiency, continuous, large-scale benefits of significant features. In recent years, the market price of raw materials, rising energy costs and higher demand for products and other functional requirements of extrusion processing more stringent requirements, more sophisticated, more efficient, more energy-efficient extrusion technology to become a typical feature The The same time as
China from the extruder to create a full set of production lines are cost-effective supply of a full set of solutions. From the mainframe and its plastic products, China can manufacture extruder including single screw extruder, suitable for processing various materials and various structures of the board, film, film, silk, rods and other products; parallel rotation Screw extruder and conical split rotary twin screw extruder, suitable for processing temperature sensitive materials such as PVC board, tube, profile, etc .; parallel co-rotating twin screw extruder, suitable for raw material blending, Filling, devolatilization, modification, feeding, adding a certain device such as melt pump, can be used for direct molding; suitable for high filler production of disc extruder, reciprocating screw extruder and so on. In recent years, with the ancillary equipment and mold technology continues to mature and development, extrusion production line has gradually become the main force of China's extruder market.
