Twin Screw Extruders
Why Choose a Coperion Co-Rotating Twin Screw Extruder?
Modern extrusion, plastics processing, and recycling require far more than simply melting polymers. Manufacturers must precisely incorporate fillers, additives, pigments, fibers, and recycled materials while ensuring homogeneous product quality, efficient production, and highest throughput rates.
Co-rotating twin screw extruders have become the industry standard for compounding because they combine several critical process functions in a single machine. Their modular design allows for precise control of conveying, melting, mixing, dispersing, devolatilization, and pressure build-up throughout the process.
With Coperion you have the partner at your side who can offer you the best solution for all your compounding and extrusion tasks. This begins with special applications on a laboratory scale and extends right through to industrial production plants.
