The 1st stage is SHJ/HT series co-rotating twin screw compounding extruder. The 2nd stage is SJ series single screw extruder.

High efficient twin-screw compounding, the finished material without die head backpressure residence, stuck into the low speed low shear single screw cooling, stabilivolt extrusion, avoiding high shear of the twin-screw which caused high melting temp. materials decompose in the twin-screw head retention.
Twin-screw is a separated, used for drying, solid, compounding part, single-screw part dedicates dry cooling stabilivolt extrusion, the decomposition function in favor of low priority of the two parts out of the main engine parameter design.
Higher efficiency and capacity: widely used in kinds of heat-sensitive materials and high powder filling operation system, such as: PVC, XLPE, halogen-free flame retardant cable, shielding material, carbon black master batch, etc.

Gear box-self made

Torque rating grade: T/A3≤8 domestic standard major parts

New structure design and high precision grinding of hardened gear teeth to ensure the gear box long time high efficiency working.

Screw-self made

Screw element is with closely intermeshed design, block type and can be easily exchanged to suit different material.

Barrel-self made

Precision grade can reach to IT 6. It is benefit for energy reduction and block type design makes it possible for various combination.
