Explore screw barrel applications for PVC pipe extrusion, PVC profile extrusion, WPC extrusion, corrugated pipe extrusion, plastic granulation, compounding, sheet and film extrusion. Select your application to review suitable screw barrel types, common processing concerns and quotation information.
Core Applications
Application
Used for PVC water supply pipes, drainage pipes and conduit pipes. Screw barrel selection should match the pipe material, machine model, output requirement and processing conditions.
Processing concerns: Stable plasticizing, output consistency, melt pressure stability and wear resistance for rigid PVC.
Used for PVC window profiles, door profiles, cable trunking and decorative profiles. Screw barrel selection depends on formula, calcium filler content, machine configuration and required surface finish.
Processing concerns: Uniform melt, smooth surface finish, dimensional stability and stable output for rigid PVC profiles.
Used for WPC decking, wall cladding, fence panels and wood-plastic composite profiles. High filler content and wood fiber can require wear-resistant screw barrel design and suitable surface treatment.
Processing concerns: Abrasive wear, high-filler compounding, stable plasticizing and consistent product surface quality.
Used for plastic pelletizing, masterbatch, filler masterbatch and recycled material compounding. Screw barrel configuration should be reviewed according to material type, filler content, throughput and mixing requirement.
Processing concerns: Mixing quality, devolatilization, filler dispersion, wear resistance and stable pellet output.
Application
Used for drainage pipes, sewer pipes and cable conduit systems. Stable melt output and suitable screw design help support forming stability, ring stiffness and line speed consistency.
Processing concerns: Melt strength, dimensional stability, cooling and forming stability, line speed consistency and wear resistance.
Application
Used for packaging films, thermoforming sheets, protective films and plastic sheet production. Screw barrel selection should support stable melt flow, thickness control and consistent surface quality.
Processing concerns: Thickness tolerance, melt fracture, optical clarity, surface smoothness and output stability.
More Applications
Bimetallic surface treatment option may be considered depending on material and wear conditions.
Selection Reference
Use this reference to match your processing application to suitable screw barrel types. The final choice may require different screw design, material or surface treatment depending on material, machine model and processing conditions.

Application Selection Help
Quick answers to help you match your produced product to a suitable screw barrel type. Final selection should be confirmed according to machine model, dimensions and processing conditions.
PE pipe extrusion lines commonly use single screw barrels. To begin a replacement review, send any available information, such as pipe material (PE, PP-R, PE-RT or PE-X), extruder model, screw diameter, L/D ratio, drawings, photos or worn samples. You do not need every item at first contact; final specifications are confirmed before manufacturing.
PVC profile extrusion lines commonly use conical twin screw barrels, especially for window profiles, door frames, trims, fences and similar rigid PVC profile products. Final selection should be confirmed according to machine model and screw barrel dimensions.
PVC wood plastic extrusion lines usually use conical twin screw barrels for wall panels, WPC boards, skirting boards, cladding and PVC fence applications. Replacement manufacturing can be supported based on machine model, dimensions and material formulation.
PE and PP wood plastic extrusion applications may use conical twin screw barrel systems depending on machine configuration, material formulation and extrusion process. For an initial review, send any available machine model, product type or processed-material information. Final selection is confirmed through technical review.
WPC mixing and granulating applications are commonly related to parallel twin screw, segmented screw or wear-resistant screw barrel requirements, especially for high filler content and compounding processes.
Start with any information you have, such as the produced product type, machine brand or model, screw diameter, L/D ratio, processed material, current production issue, drawings, photos or worn samples. You do not need every item to begin. Nanhaiya will review the available information and follow up with pricing and technical support.
Corrugated pipe extrusion commonly uses single screw barrels. To begin a replacement review, send the pipe material, extruder model, screw diameter, L/D ratio, output requirement, drawings, photos or worn samples. Final specifications should be confirmed according to machine model and forming requirements.
Sheet and film extrusion commonly uses single screw barrels. Screw barrel design should be reviewed according to processed material, required thickness control, output, surface quality and machine configuration. If drawings are not available, photos, machine model and measured dimensions can help start the review.
