Conical Twin Screw Barrel for PVC Foam Board Extrusion

Nanhaiya manufactures custom Conical Twin Screw Barrel for PVC Foam Board Extrusion. As core components of the extrusion system, the screw and barrel directly influence material conveying, plasticizing and melt processing. Their dimensions, screw geometry and surface treatment need to match the extruder design, PVC formulation and required production conditions.

PVC foam board formulations commonly contain PVC resin, stabilizers, processing aids, calcium carbonate and other additives. Different formulations and filler contents place different demands on screw geometry, plasticizing performance and wear resistance. Selecting the right screw barrel therefore requires consideration of the actual material composition and extrusion process.

For replacement projects, the screw barrel should match the original equipment dimensions, connection structure and working clearances. For new extrusion lines, the machine configuration, target output and processing requirements should be considered before finalizing the specifications.

Nanhaiya provides custom manufacturing based on technical drawings, equipment specifications, existing samples or measured dimensions. We review the application and available technical information to confirm the manufacturing requirements before quotation.

Key Features

• Customized screw and barrel dimensions for compatible PVC foam board extrusion lines.
• Manufacturing based on technical drawings, samples or measured specifications.
• 38CrMoAlA alloy steel with nitriding and other available surface treatment options.
• Matched screw and barrel manufacturing to meet equipment fitting requirements.

Technical Specifications

Applications

The Conical Twin Screw Barrel for PVC Foam Board Extrusion is designed for compatible PVC foam board extrusion equipment, including production lines for:

• PVC Celuka foam boards
• PVC free-foam boards
• Other compatible PVC foam extrusion products, subject to equipment and process requirements

Materials and Surface Treatment

Nanhaiya uses 38CrMoAlA alloy steel as a base material option for screw and barrel manufacturing. Depending on the confirmed specifications, components can undergo heat treatment, precision machining and surface nitriding to improve hardness and wear resistance. For applications involving higher filler content or demanding operating conditions, additional wear-resistant solutions, such as bimetallic treatment, can be evaluated.

The appropriate material and surface treatment depend on the PVC formulation, filler type and loading, processing temperature, screw speed and expected production conditions. Material grades and treatment specifications are confirmed according to the actual manufacturing requirements.

Customization and Technical Matching

Nanhaiya supports customized Conical Twin Screw Barrel for PVC Foam Board Extrusion for both replacement and new equipment projects. To evaluate the required configuration, please provide the extruder brand and model, screw diameter, screw and barrel dimensions, processed material, filler content and target output. Technical drawings, existing samples and equipment photos can also help confirm the manufacturing details.

For replacement components, information about existing wear conditions, operating history and current processing problems is also useful. Our team reviews the available specifications, including connection dimensions and working clearances, before confirming the manufacturing requirements.
