Conical Twin Screw Barrel for PVC Pipe Extrusion

Nanhaiya manufactures custom Conical Twin Screw Barrel for PVC Pipe Extrusion. As core components of plastic extrusion equipment, the screw and barrel work together to convey, compact, plasticize and mix PVC compounds before the material enters the forming die. Their geometry, dimensions and processing structure directly relate to material handling and extrusion conditions.

Different PVC pipe production lines require different screw configurations depending on pipe diameter, wall thickness, material formulation and target output. Nanhaiya provides customized manufacturing based on extruder models, screw diameter, center distance, effective length and installation dimensions to match specific equipment requirements.

Key Features

• Customized dimensions and screw geometry for PVC pipe extrusion equipment.
• Matched conical twin screw and barrel configurations according to machine specifications.
• Nitrided steel and other wear-resistant treatment options based on processing conditions.
• Manufacturing according to technical drawings, samples or measured dimensions.
• Dimensional inspection of critical machining and installation specifications.

Pipe Production Applications

This Conical Twin Screw Barrel for PVC Pipe Extrusion is designed for compatible PVC pipe extrusion applications, including water supply pipes, drainage pipes and electrical conduit pipes. Different pipe specifications involve different requirements for material conveying, plasticizing and extrusion output.

PVC compounds may contain resin, calcium carbonate, stabilizers and processing additives. Their proportions influence material flow, processing temperature, plasticizing conditions and component wear. Screw and barrel configurations should therefore be evaluated according to the actual formulation and production line rather than pipe application alone.

Screw and Barrel Design

Screw diameter, effective length, compression section, flight profile and feeding structure are important design considerations for PVC extrusion. These specifications need to correspond to the extruder configuration and the characteristics of the PVC compound being processed.

Nanhaiya customizes screw and barrel dimensions according to equipment drawings, existing samples or confirmed measurements. Temperature-control zones, cooling arrangements and installation connections can also be reviewed against the original machine layout to ensure that the manufactured components match the intended equipment.

Material and Wear Resistance

PVC compounds containing calcium carbonate and other mineral fillers can increase wear on screw and barrel working surfaces. Material selection and surface treatment should therefore consider filler type, filler percentage, processing temperature, operating hours and production conditions.

Nitrided alloy steel and bimetallic wear-resistant solutions can be evaluated according to the actual application. Nanhaiya reviews the material and treatment requirements before manufacturing to ensure that the selected configuration corresponds to the intended processing conditions.

Manufacturing and Quality Inspection

Nanhaiya's manufacturing process covers material preparation, CNC machining, heat treatment, surface treatment and dimensional inspection. Critical specifications, including screw diameter, effective length, center distance and connection dimensions, are checked against the confirmed technical drawings.

Machining accuracy and component matching are important considerations in screw and barrel production. Inspection focuses on key dimensions, surface condition and installation requirements to ensure that the finished components correspond to the specified extrusion equipment.

Customization and Technical Requirements

Nanhaiya supports Conical Twin Screw Barrel for PVC Pipe Extrusion for both replacement components and new PVC pipe extrusion equipment. To evaluate the required specifications, please provide the extruder brand and model, screw diameter, center distance, effective length, pipe size range, PVC formulation and target output.

Technical drawings and existing component samples are preferred for accurate dimensional matching. If drawings are unavailable, clear equipment photos and measured dimensions can support preliminary evaluation. Information about existing wear conditions and processing issues is also useful when selecting suitable materials and surface treatments.
