Factory For Screw And Barrel - LB-Extruder – Langbo

Extruder is a the core of the whole production line. In the production process, the extruder plays the transporting and plasticizing function. Through feeder, the powder pulling into the screw and barrel part, it is heated, mixed and extruded into definite product. A good extrude will ensure the consistent production and saving more energy in the continuous extrusion.

Price factor: Single screw extruder is cheaper and simpler inner structure.
Plasticizing factor: The single screw extruder is more suitable for extrusion and processing of granular materials. It has little shear degradation of the polymer but long residence time of the material in the extruder.
Processing capacity and energy consumption: Single screw extruder has lower extruder output, extrusion speed, energy consumption and per unit of output.
Operability: Single screw extruder is easy manipulation and simple process control.
Common materials: PE PPR

Price factor: Twin screw extruder is more expensive and has complicated inner structure.
Plasticizing factor: The twin screw extruder has good mixing and plasticizing ability, short residence time of material in the extruder. It is more suitable for powder processing.
Processing capacity and energy consumption: Twin screw extruder has better extruder output, extrusion speed, energy consumption and per unit of output.
Operability: Twin screw extruder is difficult manipulation and complex process control.
Common materials: PVC
