Double screw extruderIt is an efficient molding equipment developed on the basis of a single screw extruder, which achieves material transportation, mixing, compression, plasticization, and extrusion molding through the cooperation of two interlocking screws and the barrel.
Double screw extruderCore features:
Efficient mixing and plasticization
The meshing design of the twin-screw creates complex flow channels between the screw grooves, subjected to longitudinal and transverse compression, shearing, and displacement, resulting in sufficient mixing, high heat transfer efficiency, strong melting ability, and excellent exhaust effect.
Feeding performance
It can directly add high viscosity or low friction coefficient materials such as powder, strip, glass fiber, etc., with high conveying efficiency and support for multi feeding port design, making it easy to add additives or reinforcement materials.
Short dwell time
The material has a short residence time in the barrel and is suitable for processing heat sensitive materials (such as PVC and thermosetting powder coatings), reducing the risk of decomposition and lowering the amount of heat stabilizer used.
Strong self-cleaning ability
The co rotating twin-screw has small clearance at the meshing point, opposite speed direction between the screw edge and groove, high shear force, can scrape off the accumulated material on the screw, avoid degradation, and is suitable for continuous production.
Accurate process control
By adjusting parameters such as screw speed, temperature, and pressure, the extrusion process can be precisely controlled to produce products with different properties and specifications.
