Single screw extruder is mainly used for extrusion soft and hard polyvinyl chloride, polyethylene, thermoplastics, machinable a variety of plastic products, such as blown film, squeeze tubes, pressure plate, wire drawing, etc. , can also be used to melt granulation.
Plastic extruder advanced design, high quality, good plasticizing, low energy consumption, involute gear transmission, low noise, smooth operation, large loading, long life and other characteristics.
With the development of the society, the progress of science and technology, single screw extruder industry presents a new trend, changshu well below da plastic products factory talk about single screw extruder industry presents five trends!
high speed, high yield extruder high speed, high yield, also be made available to investors at a relatively low into the larger output and high returns. But, high speed plastic extruder screw speed also brought a series of difficulties to overcome, such as the material stay in the screw less time will lead to uneven material mixing plasticization, material may cause excessive shear material rapid heating and thermal decomposition, difficult control of extrusion stability will cause the extrudate geometry size, the related auxiliary device and the precision of the control system must be improved, the screw and barrel wear needs to adopt the high wear resistance and high wear-resisting material, under the condition of the high speed reducer and bearing problems need to be resolved such as how to improve their life.
efficient and more functional efficiency of the single screw extruder is mainly manifested in the high output, low energy consumption, low manufacturing cost. In terms of functions, plastic extruding machine is not only used in polymer extrusion molding and mixing process, its use has been widened to food, feed, electrode, building materials, packaging, pulp, ceramics and other fields. In addition, the mixing granulation and incorporated in the extrusion molding process & other; One-step extrusion process & throughout; Is also worth attention.
more and more motors to realize large-scale extrusion molding equipment can lower the production cost, which in large twin-screw granulation unit, blown film machine, pipe extrusion unit has more obvious advantages. The major technical equipment required for the national key construction service, form a complete set of large ethylene project, one of the three major key equipment of large extruding and granulating machine group rely on imports for a long time, so we must speed up the localization process, can meet the needs of the petrochemical industry development. Motors can improve the value of products, such as multilayer co-extrusion composite films are need precise extrusion, and as one of the important ways to realize precise extrusion? 吗? The melt gear pump must intensify efforts to develop research.
modularization and specialized production can adapt to the special requirements of different users, shorten the development period of new products, strive for more market share; And specialized production extrusion equipment for each system module components can be arrange designated production even for global purchasing, this to ensure the quality of the whole period, reduce cost, accelerate the capital turnover is very favorable.
intellectualization and networking of the extruder of developed countries has been widely used in modern electronic and computer control technology, the process parameters of the extrusion process such as body temperature, melt pressure and temperature, paragraphs main screw and feed screw speed, feed feed rate, the proportion of all kinds of raw materials, such as current voltage of the motor parameters online testing, and USES the microcomputer closed-loop control. Some companies have been using the Internet, remote monitoring, diagnosis and control to network control extrusion molding line. This to ensure stability in the process conditions, improve the accuracy of the product is very good.
