This video showcases Thermal Press International’s Dual C-Series machine, also known as the Port Sealer Thermal Press, being used to heat seal a disc port onto a bioreactor bag for critical single-use biroprocessing applications. Bioreactor bags require strong, consistent, and leak-resistant seals to maintain sterility, preserve process integrity, and support reliable fluid handling throughout production.
The system is engineered to deliver controlled heat, pressure, and dwell time to create a precise bond between the port disc and flexible bag material without damaging surrounding film layers. This level of process control is essential when sealing components used in biopharmaceutical and biotechnology manufacturing environments where quality and repeatability are critical.
Thermal Press International’s Dual C-Series platform is designed for efficient production while maintaining sealing consistency across demanding applications. Custom tooling and fixturing help ensure accurate part placement, repeatable alignment, and dependable results from cycle to cycle.
Applications such as disc port sealing on bioreactor bags demonstrate TPI’s expertise in heat sealing flexible medical and industrial materials for regulated manufacturing environments. Whether for pilot production or higher-volume manufacturing, TPI provides customized thermal assembly solutions tailored to the specific needs of each application.
