Features and application

This set is advanced in design,high in output,good in plasticization and low in energy consumption.The involute gear driving is characterized by low niose,stable working,big bearing capaciry and long serice life,This set can be used for extruding thermo-plastics like soft or hard polyvinyl chlorid (PVC) and polystyrene(PE).Coordinated with the appropriate auxiliary machine (including the head of former),if can produce many kinds plastic products such as film,pipe,board,braid,belt as well as granule.

Two stages styles unitary design, reinforcing plasticization capacity guaranteed high performance and high velocity extruding. The particular kind of barrier, BM type synthetical mixing design guaranteed blending effect.High shear and low melting temperature

The design conception
*High production capacity and high velocity extruding on the high quality base;
*Low temperature plasticization?design guarantees high quality product.
*High twisting force output, the huge thrust bearing;

*The gear and shaft is high intensity alloy steel, and are treated by carburizing and tooth grinding. .
*High hardness and clean degree, and extremely low noise;

*The charging hopper style automatic drier guards against the material from damp.

*Automatic feeder effectively reduces labour intensity;
*May select weight in feeding unit to control product weight.
*Automatic PLC intelligence control to achieve the linkage action of main machine and auxiliary machine;
*Man-machine interface easy to supervise, the process and the machinery condition can be conveniently comprehended;
*Control mode (temperature control meter) may be replaced in the light of requirements.
* Material character is 38CrMoALIA, nitrogen treatment;
*Strict temperature control uracy, wind cooling and water cooling unite;
* The distinctive feeding inlet with consummate water-cooling unit design.
*The bushing is designed to specialized ladder-shaped trough;
*The barrel with channel surface feeding base suit has the function of increasing capacity, which ensure high velocity and production capacity.

The pipe extrusion:
