Single Screw Extruder for Plastic Processing

Product Overview

The URIDGE Single Screw Extruder for Plastic Processing is a configurable single-screw extrusion platform. It can be supplied as a standalone machine or integrated as the main extruder of a complete pelletizing, pipe, sheet or profile line.

Because different materials and final products require different screw geometry, L/D ratio, feeding, degassing, motor and processing configuration, each extruder is configured according to the application rather than supplied as one fixed machine for every use.

Applications

• Plastic pelletizing
• Pipe extrusion
• Sheet extrusion
• Profile extrusion
• Standalone extrusion applications

Material Compatibility

The extruder can be configured for thermoplastics including PE, PP, PVC, ABS, PA, PET and PC, and other suitable thermoplastic materials.

Screw Design for Different Materials

Screw geometry is selected according to the polymer, formulation and final product. Different materials do not all use the same screw design.

L/D Configuration

The series covers L/D ratios from 8:1 to 44:1, with 30:1 and 33:1 as common configurations. The L/D ratio is chosen according to the material and processing requirement.

Screw & Barrel Materials

The standard screw and barrel are made from 38CrMoAlA. Alloy screw options are available according to the material and processing requirements.

Heating and Fan Cooling

Heating options include ceramic, infrared, stainless-steel and cast-aluminum heaters, with fan cooling for barrel temperature control.

Feeding Options

Feeding can use a single-screw feeder or a twin-screw feeder according to the material form. The twin-screw option refers to the feeder, not to the main extruder, which remains a single-screw machine.

Optional Vacuum Degassing

Vacuum degassing is available as an option according to the material and process requirement.

Siemens PLC / HMI and VFD Control

The extruder uses Siemens PLC and HMI control with variable-frequency drive for adjustable operating speed.

Standard Models

Note: The values above represent common configurations. Actual output depends on the thermoplastic material, formulation, screw design, L/D ratio, feeding method and final application. URIDGE can configure screw diameter, L/D ratio, motor power and processing capacity according to specific production requirements.

Full Configuration Range

Standalone or Complete-Line Integration

The extruder can be purchased as a standalone machine or supplied as the main extruder within a complete production line, according to the customer’s process.

Frequently Asked Questions

What plastics can the single screw extruder process?

It can be configured for PE, PP, PVC, ABS, PA, PET and PC and other suitable thermoplastics.

What screw diameters are available?

The series covers screw diameters from 20 mm to 220 mm, with common models at 45, 65, 90, 120, 160 and 200 mm.

What L/D ratios are available?

L/D ratios range from 8:1 to 44:1, with 30:1 and 33:1 as common configurations.

Can the extruder be used for pipe, sheet, profile and pelletizing applications?

Yes. The extruder can be configured as the main machine for pelletizing, pipe, sheet and profile extrusion, or used standalone.

Does every material use the same screw design?

No. Screw geometry, L/D ratio and feeding are selected according to the material and final product.

Is vacuum degassing available?

Yes. Vacuum degassing is optional according to the material and process requirement.

Can I purchase the extruder as a standalone machine?

Yes. It can be supplied standalone or integrated into a complete line.

How do I select the correct extruder size?

Please provide the raw material, formulation, final product, required output and downstream process. URIDGE will select the screw diameter, L/D ratio, motor, feeding system and other configuration according to the application.
