Twin-Screw Extruder

What is a Twin-Screw Extruder?

A twin-screw extruder has two intermeshing screws rotating inside a barrel.

The screws can be co-rotating (both rotate in the same direction) or counter-rotating.

The design enhances mixing, heat transfer, and pressure generation.

High-Torque Twin-Screw Extrusion Lines

High-torque refers to the ability of the extruder to exert very strong rotational force on the screws.

This enables processing of highly viscous, filled, or reinforced materials which need more mechanical energy to melt and mix.

Often used for compounding plastics with additives, fillers, or fibers.

Key Features:

Robust Drive System: Motors and gearboxes designed to deliver high torque at relatively low screw speeds.

Intermeshing Screws: Provide efficient mixing and shearing.

Modular Screw Design: Screw elements can be customized for different processing needs.

Advanced Controls: For temperature, speed, and pressure to ensure consistent quality.

Versatile: Can handle a wide range of materials including thermoplastics, elastomers, and reactive systems.

Applications:

Polymer compounding and masterbatch production

Recycling of plastics

Production of food, pharmaceuticals, or chemicals requiring intensive mixing

Processing filled or fiber-reinforced composites

Advantages:

Superior mixing and homogenization

Ability to handle difficult or abrasive materials

Enhanced process control and product quality

Increased throughput due to higher torque capacity
