Product Description
JWELL Counter-Rotating Parallel Twin Screw consists of two parallel cylindrical screws that rotate in opposite directions. The configuration is developed for extrusion processes requiring controlled material conveying, stable shearing and effective venting within the barrel.
Another important characteristic is the good exhaust effect. Effective venting supports the removal of gas from the material during processing and contributes to the stability of the finished product. Together, the low-speed operation, reduced heat generation, uniform shear, material conveying and venting characteristics define the operating advantages of this counter-rotating screw arrangement.
The main applications listed in the source document include PVC pipe and profile extrusion, along with PE and PP sheet and board products. The parallel cylindrical construction distinguishes this product from conical twin-screw configurations, while the opposite rotation direction distinguishes it from co-rotating parallel twin-screw systems.
For product selection or quotation, customers should provide the processed polymer, intended product, extrusion equipment model and operating requirements. Screw diameter, effective length, L/D ratio, rotational speed and output requirements should also be confirmed because no numerical specifications are included in the source document.
