How does a Single Screw Extruder work?
First Step:Feeding the resins or pellets
A polymer, as powder or pellet, is continuously fed from the hopper into the extruder barrel.
Second Step:Melting of the resins
The heated barrel melts the polymer and transports the material through the die.
Third Step:Actual extrusion process
The screw channel exerts the force on the polymer by the rotating screw while the stationary barrel gives a breaking force to the rotating polymer and makes the polymer slip slightly on the screw surface.
Forth Step:Cooling it down
After passing through the die, your plastic passes through the cooling zone.
The Last Step:Final finishing procedures
Involves putting the final touches on your plastics. This includes drilling, printing, bending or cutting.
