Put powder or granules and butyl ester, waste material, extruder, calcium powder into the hopper of plastic extruder, and use high speed mixing bucket to stir continuously and uniformly. The uniformly stirred plastic raw material is extruded from a hole head or metal mesh with high extrusion pressure of a plastic extruder.
What are the production steps of plastic extruder?
What are the classifications of plastic extruders?
How to choose a plastic extruder?
Normally, after material is put into plastic extruder, it is extruded by screw. After using frequency inverter speed control technology, the pressure can be controlled so that the suitable linear speed can be selected.
The extrusion molding of the plastic extruder is to continuously mold the polymer melt (or viscous fluid) through a certain shape of the die under the extrusion action of the extruder screw, and the obtained product is a continuous profile with a constant cross-sectional shape .
There are two types of plastic extruders: screw plastic extruder and piston plastic extruder. The former is continuous extrusion and the latter is discontinuous extrusion. Plastic screw extruders can be divided into single screw extruders, twin screw extruders, vented plastic extruders and multi-screw extruders, and single screw extruders are currently the most widely used in production. , is also the most basic plastic extruder. In recent years, the twin screw extruder has developed rapidly, and its application has gradually become widespread. At present, plastic extruders, single screw extruders have been gradually eliminated in the processing of PVC plastic door and window profiles, and twin screw extruders have become the main production equipment, but single screw extruders are used in the extrusion processing of other polymers. Out of the machine still dominates. Piston type plastic extruder is mainly used to mold high viscosity materials such as polytetrafluoroethylene, ultra-high molecular weight polyethylene and so on.
After you have determined the suitable granulation machine and equipment, look for the corresponding plastic granulator manufacturer and plastic granulator price. Mainly to investigate the size of manufacturers, production strength, small plastic extruders and reputation of customers using machinery and equipment. Do not be afraid of the long journey. The key to buying a plastic extruder is to buy the right one with a good price-performance ratio, with strong technology and after-sales service, so you can not worry. If you only buy cheap or nearby machinery and equipment, the performance and product quality will be unstable, and the time, labor and money spent will far exceed the initial investment in machinery and equipment
