Pharmaceutical twin screw extruders
Optimize the mixing and extrusion of active pharmaceutical ingredients with unmatched precision and flexibility, ensuring enhanced bioavailability and innovative controlled-release formulations for medical applications.

Processes APIs and Solid Dosage Forms
The ZSK Pharma Twin Screw Extruders from Coperion are engineered to enhance the continuous processing of active pharmaceutical ingredients (APIs) and solid dosage forms. Featuring a modular design, these extruders provide flexibility in processing with adjustable barrel and screw configurations, ensuring precise mixing and controlled temperatures to prevent API degradation. Ideal for producing controlled-release tablets, sustained-release capsules, and transdermal drug delivery patches, they are instrumental in pharmaceutical applications requiring high levels of dispersion and encapsulation. The ZSK Pharma Extruders offer specific torque of up to 18 Nm/cm³, accommodating high throughput while maintaining product integrity. Integrated with PLC control systems that comply with CFR Part 11, they facilitate seamless automation and easy scale-up from R&D to full-scale production. Constructed in GMP-compliant stainless steel with FDA-compliant lubricants, these extruders ensure reliability and safety. The self-cleaning twin screws and compact design allow for quick operation, reduced maintenance, and minimal space requirements, supported by Coperion’s extensive engineering expertise and after-sales service network.
