Look at the drive for extrusion moulding

Release date:2019-08-09 00:00 Source:http://mjaupanda.com Views:

The operation mode of Dalian extrusion moulding has been progressing from manual to mechanical to hydraulic, but in this period, no matter what form, it only reflects the difference of operation difficulty and labor intensity. The essence of production process: intermittent is the common characteristic of extruders in that period. Extruded rubber is not a problem, but for thermoplastics it is impossible to meet the requirements of plasticization.


In addition to increasing the ratio of length to diameter of extruder screw, many improvements have been made in heating mode, feeding device and transmission device. By 1939, they developed the plastic extruder to a new stage, and the polymer can only be used as a valuable product through moulding. Molding is an indispensable part of the production of polymer materials. Modified polymer materials were prepared by extrusion.


意甲下注Blend reinforcement, toughening technology, radiation modification technology, nano-composite technology, and other new modification technologies; extruders and production lines with various structures and functions; mixing screw, exhaust extruder, twin-screw, multi-screw extruder, reactive extruder, combined extruder, suitable for polymer materials Forming device based on physical and chemical characteristics.


意甲下注But in the application of these technologies, we can continue to innovate, develop new products, manufacture new materials and form new technologies. Compared with other polymer forming methods, extrusion has many outstanding advantages. It can also be used for continuous mixing, plasticizing and granulation of filter rubber and raw rubber. In the process of producing resin in petrochemical plant, extruder can be used to extrude the moisture in resin.


意甲下注The mixing of additives and modifiers in various brands of resins was completed by extruder, and the granulation process of resins was completed. The production of plastic products that are fully used or contain extrusion processes accounts for about half of the total amount of thermoplastic products. The products formed by this method are used in agriculture, construction, petrochemical industry, machinery manufacturing, medical equipment, automobile, electronics, aerospace and other industrial sectors.
