FAQ — Screw Barrel Ordering, Custom Manufacturing & Technical Support

Please provide your machine brand/model, screw or barrel dimensions, processed material, product application, current production problem, drawings, photos, worn samples or measured dimensions. If you know the required material or surface treatment, you can also include it. You can send these details through our contact / RFQ form.

Yes. We can evaluate the request based on machine model, photos, worn samples and measured dimensions. Final production details should be confirmed before manufacturing.

Custom orders can be discussed according to product type, size, material, processing requirements and current production schedule. Please send the application details for confirmation.

We usually confirm the machine model, screw diameter, barrel size, working length, processed material, application, current issue and available drawings or samples before recommending a suitable solution. For application-based selection, see our Applications page.

PVC pipe extrusion commonly uses conical twin screw barrels or parallel twin screw barrels. The final selection depends on PVC formulation, pipe size, output requirement, extruder model and working conditions. For a full application-to-product overview, see the Applications page.

PVC profile extrusion commonly uses conical twin screw barrels or parallel twin screw barrels. Screw barrel design should match the PVC formulation, profile structure, extruder model and output requirement.

WPC extrusion can use conical twin screw barrels or parallel twin screw barrels. For high-wear WPC materials, bimetallic or alloy treatment may be considered according to wood powder, filler content and working conditions.

Film blowing and plastic bag production commonly use single screw or extruder screw barrels. The design should be confirmed according to PE, PP, HDPE, LDPE or other processed materials and machine requirements.

Plastic granulation and compounding may use parallel twin screw barrels or single screw barrels depending on material, mixing requirement, filler content and equipment type. Bimetallic or alloy treatment may be considered for abrasive materials.
