▏Applications

Applications of Small single screw extruder

The small-scale extruder is widely used in:

Laboratory Research: Ideal for polymer testing and formulation development.

Plastic Pellet Production: Suitable for small-batch compounding and color masterbatch production.

Material Experimentation: Useful for developing biodegradable plastics and high-performance materials.

Educational Institutions: Training students in polymer processing and extrusion technologies.

Medical and Specialty Plastic Production: Small-scale production of medical-grade plastic components.


▏Advantages of Small Single Screw Extruder

Feature Benefits
Compact Size Requires minimal space, making it ideal for labs and small workshops.
Low Material Consumption Ideal for research and development with minimal raw material use.
High Precision Ensures uniform melting and mixing of plastic materials.
Cost-Effective Lower investment compared to industrial-scale extruders.
Customizable Configurable to specific materials and production needs.


▏Configuration Options

The small extruder machine for plastic pellets production can be customized based on client requirements. Typical configurations include:

  • Screw Diameter: Ranges from 20mm to 50mm depending on throughput needs.

  • L/D Ratio (Length to Diameter): Adjustable from 10:1 to 30:1 for different processing requirements.

  • Temperature Zones: Multiple independent heating zones for precise thermal control.

  • Screw Material: High-grade nitrided steel for durability and wear resistance.

  • Control System: PLC or digital control with touch screen interface.


▏Production Process Flow

The production process using a laboratory extruder follows these steps:

  1. Material Feeding: Raw plastic pellets or powders are loaded into the hopper.

  1. Melting and Mixing: The single screw mechanism gradually melts and homogenizes the material.

  1. Extrusion Through Die: The molten plastic is forced through a die to shape it.

  1. Cooling and Solidification: The extrudate is cooled using air or water baths.

  1. Cutting and Pelletizing: The final product is cut into uniform pellets or shaped into required forms.

  1. Collection and Packaging: Finished products are collected, inspected, and packaged for use.
