Who knows the temperature regulation method of the extruder?Any information will do
1, extrusion methodAccording to plasticizing methods: dry extrusion and wet extrusionPress the way: continuous extrusion and intermittent extrusion2, characteristicsContinuous production, high efficiency, simple operation, wide range of applications [Edit] paragraph extrusion molding equipment 1, the hostExtrusion system: composed of screw and barrel, it is the key part of extruder. Its function is to melt plastics, quantitative, constant pressure, constant temperature extrusion of meltDrive system: drive the screw to increase the required torque and torqueHeating and cooling system: guarantee the temperature of plastic and extrusion system in molding process2 auxiliariesIt is composed of head, setting device, cooling device, traction device, coiling device and cutting3 、 control systemIt consists of electric apparatus, instrument and actuating mechanismPurpose: to control the main and auxiliary motor, in order to meet the demands of speed and power; control main engine temperature and pressure and flow, to ensure product quality; to achieve automatic control of the extrusion unit, ensure the coordinated operation of main and auxiliary equipment. [edit this paragraph] extruder extruder overview of plastic extruder is the host, it consists of extrusion system, transmission system and the heating and cooling system.
Extrusion molding in plastic processing is called extrusion, using hydraulic pressure in rubber extruder processing in extrusion die extrusion. That itself means that the material through the extruder barrel and screw the function between the side heating plasticization, screw edge is pushed forward, a processing method of continuous head made by various sections of finished or semi-finished products.In the fiber chemical industry is also useful in the extruder to the spinneret for melt spinning. The material, process of extrusion used in thermoplastic plastics and rubber, for batching, granulation, rubber filtration, continuous production, manufacturing various continuous products such as pipe, profile, sheet (or sheets), thin film wire and cable coating, rubber tire, tube noodles barrel, a sealing strip, the production efficiency is high. In the production of synthetic resin, can be used as reactor extruder, continuous polymerization and processing, in rubber industry, the compression ratio of different extruding machine can be used to unmasticated natural rubber of different materials. Compression extrusion machine than some different. [edit this paragraph] the principle of extrusion molding material since the bucket into the barrel, the screw rotates under the action of the cylinder wall and the surface of the screw friction shearing forward delivery to the feeding section in the loose. Forward transport also is compacted; the compression section, screw groove depth, further compaction, while the barrel heating and screw and cylinder wall friction shear, the material temperature rise began to melt, the compression section ends; homogeneous section material uniform, constant temperature, fixed quantity, squeeze out to melt. After a head forming, by setting the product.
