擠塑機(jī)也是塑料機(jī)械的主要品種之一,占塑料機(jī)械總產(chǎn)值的31%,用擠塑機(jī)加工的塑料制品占其總量的1/3左右。 單螺桿擠塑機(jī)發(fā)展的主要標(biāo)志在于其關(guān)鍵零件——螺桿的發(fā)展。近幾年以來,人們對(duì)螺桿進(jìn)行了大量的理論和實(shí)驗(yàn)研究,至今已有近百種螺桿,常見的有分離型、剪切型、屏障型、分流型與波狀型等 單螺桿擠塑機(jī)無論作為塑化造粒機(jī)械還是成型加工機(jī)械都占有重要地位,近幾年業(yè),單螺桿擠塑機(jī)有了很大的發(fā)展。目前德國生產(chǎn)的大型造粒用單螺桿擠塑機(jī),螺桿直徑達(dá)700mm,產(chǎn)量為36t/h。 從單螺桿發(fā)展來看,盡管近年來單螺桿擠塑機(jī)已較為完善,但隨著高分子材料和塑料制品不斷的發(fā)展,還會(huì)涌現(xiàn)出更有特點(diǎn)的新型螺桿和特殊單螺桿擠塑機(jī)。從總體而言,單螺桿擠塑機(jī)向著高速、高效、專用化方向發(fā)展

Extruder Plastics Machinery is one of the main species, accounting for 31% of the total output value of plastic machinery, plastic processing by extrusion machine of its products, the total 1 / 3.
Single screw extruder main symbol of the development of key parts in its - the development of screw. In recent years it has been carried out on a lot of screw theory and experiment, has been nearly a hundred kinds of screw, has separated the common type, shear type, barrier type, shunt type and wave type, etc.
Either as a single screw extruder or molding plastics processing machinery pelletizing machine occupy an important position in the industry in recent years, single screw extruder with a great development. Germany's large-scale production of granulation with a single screw extruder, screw diameter 700mm, output of 36t / h.
The development of a single screw from the point of view, although in recent years, single-screw extruder have been better, but with the polymer materials and plastic products continues to develop, will emerge more new features and special single-screw screw extruder. Overall, single-screw extruder toward the high-speed, efficient and dedicated direction of development
