Newest Conical Twin Screw Extruder

A conical twin screw extruder consists of two tapered screws rotating inside a barrel. The screw diameter gradually increases from the feeding section to the discharge section, providing strong conveying ability and efficient plasticization. With a conical twin screw structure, it provides efficient mixing, stable plasticization, and uniform melt output for PVC pipe, profile, wall panel, and sheet production.

Application: rigid PVC, foam PVC, WPC, PE WPC, etc
Application: Pipes, profiles, wall panels, door panels, sheets, and other plastic products

As a professional plastic machinery manufacturer, EANS conical twin screw extruders are widely used in complete PVC extrusion lines, offering reliable performance, energy-efficient operation, and customized solutions for different PVC processing applications.

ADVANTAGE OF EANS CONICAL TWIN SCREW EXTRUDER

plastic extrusion expert

1. Efficient Mixing and Plasticizing
Two intermeshing screws provide effective material conveying, mixing, and plasticization, ensuring a homogeneous melt for consistent extrusion.
2. Strong PVC Processing Capability
The conical twin screw structure is particularly suitable for PVC processing, providing stable conveying and plasticizing performance for rigid and filled PVC compounds.
3. High Torque and Stable Output
The twin-screw configuration delivers strong conveying capability and stable extrusion pressure, supporting continuous production with consistent output.
4. Excellent Filler Dispersion
The intensive mixing action helps disperse calcium carbonate, stabilizers, pigments, and other additives more evenly throughout the PVC compound.
5. Controlled Plasticization
The conical screw geometry provides progressive compression and plasticization, helping achieve the required melt condition while reducing unnecessary shear during PVC processing.
6. Good Self-Cleaning Performance
The interaction between the two screws helps reduce material accumulation inside the processing section, making material replacement and production changeovers more manageable.
7. Suitable for High-Filler Formulations
The strong conveying and mixing capability makes the conical twin screw extruder suitable for PVC formulations with relatively high levels of fillers, helping manufacturers balance material cost and product performance.

FAQ

What materials can the conical twin screw extruder process?

The conical twin screw extruder is mainly designed for PVC resin and can process formulations containing calcium carbonate and other additives. The actual formulation can be adjusted according to the target product and required properties.

What products can be produced with a conical twin screw extruder?

The conical twin screw extruder can be configured for PVC pipes, profiles, wall panels, door panels, sheets, skirting boards, and other shaped plastic products by matching the appropriate die and downstream equipment.

Why is a conical twin screw extruder suitable for PVC processing?

A conical twin screw extruder provides strong conveying, mixing, and plasticizing performance while allowing controlled processing of PVC compounds. Its progressive screw geometry is well suited to the processing characteristics of rigid PVC.

What is the difference between conical and parallel twin screw extruder?

Both conical twin screw extruders and parallel twin screw extruders use two intermeshing screws to melt, mix, and transport plastic materials. The main differences are the screw shape, processing characteristics, output range, and typical applications.

How to choose a conical twin screw extruder for PVC production?

Choosing the right conical twin screw extruder for PVC production depends on several factors, including the PVC product type, required output, material formulation, screw design, and production requirements. A properly selected extruder can improve plasticization quality, production stability, and energy efficiency.

What determines the output of a conical twin screw extruder?

Extrusion output depends on the extruder model, screw diameter, screw design, motor power, PVC formulation, die resistance, and processing conditions. Therefore, the rated output should be selected according to the actual production requirements rather than the extruder model alone.
