Extruder



To achieve required extrudate the palletized compound is fed into extruder through gravity filling bunker. It is heated and melted to uniform flow mass inside the cylinder of the extruder.

Extrusion Process



Then melt flow is transferred and pressed through the slit of the die. This is done by a screw rotation inside the extruder cylinder generated by v-motor.

Cooling section



Uniform cooling around/along the outlet of extrusion die is considered to be very important factor of the extrusion process. Cooling equipment comprises water tank furnished with auxiliary sizing facilities. Extruded blank is pulled by the tractor through the water and cooled. While passing under water along the cooling tank the extruded profile is subjected to shrinkage due to temperature drop. However the size of the product depends not only upon cooling but also upon the speed of traction. 
 

Tractor (puller)



Tractor (puller) is a caterpiller-type machine, that pulls the extruded blank through water tank, pushing it further on downstream to cutter and handling table. The tractor pulls the extruded profile with uniform speed, without allowing it to slip. This process is closely related to final dimensions of the finished product.
