Applications Scenarios
Product Description
The JWELL conical twin screw is designed primarily for processing PVC products and other heat-sensitive materials. Its conical configuration operates at a relatively low rotational speed, allowing the material inside the barrel to experience stable and uniform shear during plasticization. This operating characteristic makes the screw suitable for extrusion tasks where excessive shear or extended thermal exposure should be avoided.
Compared with longer processing structures, the relatively short screw helps shorten the time that material remains inside the barrel. The combination of low-speed rotation, uniform shear and reduced residence time supports the controlled plasticizing and forming of heat-sensitive compounds. It is therefore particularly relevant to PVC processing, where the material must be handled carefully throughout the extrusion process.
The product can serve a broad range of extrusion applications. Typical uses listed in the source material include PVC pipe, PE/PP/PVC wood-plastic composite extrusion, PVC skinning foam board, PVC profiles, PVC and PP corrugated pipe, PVC flooring products and PVC waterproof membranes. This application coverage makes the conical twin screw suitable for manufacturers producing both rigid and formed plastic products with different shapes and end uses.
For product selection, the screw configuration should be matched to the processed material, product type and the technical requirements of the existing extrusion equipment. Customers can provide the extruder model, processed formulation, current screw information and intended application for technical matching. Because screw diameter, L/D ratio, construction material, surface treatment and output capacity are not specified in the original product document, these values should be confirmed separately for each project.
