The applications of asisted extrusion technologies such as vibration extrusion,lubricating extrusion, gas-asisted extrusion in polymer extrusion were presented to overcome the deffects of low extrusion rate in normal extrusion.

Effect of extrusion velocity to wear degree of aluminum profile;

The high speed extrusion behaviors of several polyolefine melts were investigated by a double capillary rheometer of constant speed type.

In order to ensure the quality of extruded products for high speed extrusion with the speed higher than 300r/min,besides improving the structure of the machinery,the cooling equipment in the metering zone becomes particularly important.

The property of insulative PE in high speed extrusion was studied in the paper.

The Study Of Lubricant Concentrating For High-Speed Extrusion;

Breaking traditional mechanism modeling methods, by using system identification modeling methods, the relationship of extruding power and swing and frequency was established when extruding LDPE with vibrating field.
