1. The driving V-belt is severely worn, causing slipping during work.
2. The center distance of the V-belt drive pulley is too small, so that the V-belt drive cannot correctly friction drive with the trapezoidal slope of the pulley.
3. The temperature of the heating material in the barrel is low, and the raw material is not uniformly plasticized, which causes an increase in the working load torque of the extruder screw, and unstable screw speed of the extruder .
4. The thrust bearing of the extruder screw is damaged.
1. The geometric shape and size error of the product is large.
2. The product will often appear horizontal wrinkles.
3. The surface of the product is rough, brittle, or partially hard.
Our company specializes in the production of parallel and co-rotating modular screw element, barrels and screws, covering various models from Ø20mm to Ø300mm.

CKE elements combine conveying and mixing functions, providing gentle material exchange with low shear and reduced energy consumption.
Best suited for:
Heat-sensitive materials
Low-shear compounding processes
Applications requiring stable conveying with mild mixing
SK conveying elements provide approximately 15% higher free volume than standard conveying elements and are particularly suitable for low bulk density materials.
Best suited for:
Feeding zones
Side feeding
Low bulk density materials
Single flight conveying elements provide higher conveying efficiency than standard double flight elements. Their wider flight design reduces leakage flow and increases pressure-building capability.
Best suited for:
Feeding sections
Extrusion zones
Applications requiring strong conveying force
Reverse kneading elements introduce backflow and pressure build-up, increasing residence time and enhancing mixing intensity.
Best suited for:
Before venting zones
Degassing preparation
High mixing demand sections
Forward kneading elements provide a balance between conveying and mixing, with adjustable shear depending on stagger angle and disc width.
Best suited for:
Plastication zones
General compounding
Controlled mixing processes
Stretching elements, also called S-type elements, improve material exchange and distributive mixing in partially melted zones.
Best suited for:
Semi-plasticized material zones
Improved dispersion
Gentle mixing processes
