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 accuracy, 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.
