In today’s fast-evolving recycling industry, efficiency, consistency, and material adaptability are more crucial than ever. At Rumtoo Machine, we understand the unique challenges faced by manufacturers and industrial recyclers. One technological solution that is transforming the landscape of plastic recycling is the Twin-Screw Extruder—a powerful, versatile system offering unmatched benefits for reclaiming and reprocessing plastic materials.
What is a Twin-Screw Extruder?
A Twin-Screw Extruder is an advanced plastic processing machine featuring two intermeshing screws rotating inside a barrel. Unlike single-screw extruders, twin-screw systems enable more effective mixing, compounding, and devolatilisation—key factors when working with contaminated or mixed plastic waste streams.
Rumtoo Machine’s extruders are engineered for superior control, throughput, and customisation, making them ideal for handling today’s demanding plastic recycling processes.
Key Applications in Plastic Recycling
1. Processing Mixed and Contaminated Plastics
Twin-screw extruders are especially suitable for handling complex plastic mixtures such as post-consumer or post-industrial waste. At Rumtoo Machine, we integrate venting systems and degassing ports that effectively remove volatiles and moisture—ensuring consistent product quality.
2. Compounding Recycled Materials
Combining recycled polymers with fillers, fibres, or additives is critical for value-added manufacturing. The design of twin-screw extruders allows precise ingredient metering, uniform distribution, and enhanced mechanical properties in the final product.
3. Pelletising and Repelletising
Rumtoo Machine’s twin-screw systems are optimised for pelletising recycled plastics into reusable granules. Our systems maintain excellent pellet uniformity, an essential requirement for high-end applications like injection moulding or extrusion-grade products.
Advantages of Twin-Screw Extruders in Plastic Recycling
1. Superior Mixing and Homogenisation
The intermeshing screw elements of a twin-screw extruder promote high shear and intensive mixing—vital for achieving uniform polymer blends.
2. Higher Throughput
Rumtoo Machine’s twin-screw systems offer enhanced throughput due to more efficient melting and pressure generation, resulting in faster processing and higher yields.
3. Excellent Material Flexibility
Whether recycling PE, PP, PET, or engineering plastics, our twin-screw extruders are designed to handle a broad range of materials without compromising on quality or output.
4. Effective Degassing
Our extruders include strategically placed venting zones to eliminate gases, moisture, and low-molecular-weight compounds, ensuring a stable and reliable output.
