Talking about the Performance Characteristics of Extrusion Molding

Release date:2019-07-12 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. He converted his own screw extruder into a product for sale.


意甲下注In 1880, American J. Royle also developed a screw extruder. Several different types of extruders have emerged in recent years. By 1939, they had developed the plastic extruder into a new stage, which may be called "modern single screw extruder stage".


意甲下注This stage is characterized by direct electric heating, air cooling, automatic temperature control device, lined barrel and screw surface nitriding treatment, screw length-diameter ratio of 10, continuously variable transmission device, etc. Means of the new process have been pushed forward in an all-round way. As one of the polymer processing technologies, extrusion moulding technology is growing with the development of polymer processing industry technology.


Nano-composite technology, as well as 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, moulding device adapted to the physical and chemical characteristics of polymer materials.


意甲下注If extruder cooperates with calender, calendering film can be produced; with press, various pressing parts can be produced; with blow moulding machine, hollow products can be produced. As long as the screw and head are replaced according to the material performance characteristics and the shape and size of the product, different products can be produced.
