Explore screw barrel applications for PVC extrusion, WPC extrusion, film blowing, granulation, compounding and injection molding. Select an application to understand suitable screw barrel types, processing concerns and quotation information.
Core Applications
Commonly used for PVC water supply pipes, drainage pipes and conduit pipes. The screw barrel selection depends on material, machine model and processing conditions.
Processing concerns: Common processing concerns include stable plasticizing, output consistency and wear resistance for rigid PVC.
Relevant Products
Suitable for PVC window profiles, door profiles, cable trunking and decorative profiles. The suitable screw barrel type can vary with formula and machine configuration.
Processing concerns: Common processing concerns include surface finish, dimensional stability and uniform melt for rigid PVC profiles.
Relevant Products
Can be used in WPC decking, wall cladding, fence panels and wood-plastic composite profiles. Highly filled wood-plastic materials may require different screw design or surface treatment.
Processing concerns: Common processing concerns include abrasive wear from wood fillers and consistent compounding of high-filler formulas.
Relevant Products
Commonly used for PE/PP film, packaging film, shopping bags and garbage bags. Single screw barrels are widely applied in film blowing lines depending on material and machine model.
Processing concerns: Common processing concerns include melt uniformity, film thickness consistency and stable output for thin-film applications.
Relevant Products
Suitable for plastic pelletizing, masterbatch and recycled material pelletizing. The screw barrel configuration may require different designs depending on material and throughput.
Processing concerns: Common processing concerns include mixing quality, devolatilization and wear resistance when handling fillers or recycled material.
Relevant Products
Can be used in household plastic parts, automotive plastic parts, electrical appliance parts and engineering plastic components. Screw selection depends on material and injection machine model.
Processing concerns: Common processing concerns include plasticizing stability, shot consistency and wear resistance for reinforced or filled grades.

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. For replacement quotation, please provide pipe material such as PE, PP-R, PE-RT or PE-X, extruder model, screw diameter, L/D ratio, drawings, photos or worn samples.
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. Please provide machine model, product type and processed material for confirmation.
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.
Please send your produced product type, machine brand and model, screw diameter, L/D ratio if available, processed material, current production issue, drawings, photos or worn samples. Nanhaiya will review the information and follow up with pricing and technical support.
