evomix DF: Potting of dialysis filters
High precision and reliability for potting of two-part polyurethane
The production of medical devices always requires particularly high levels of care and accuracy. The production process for dialysis filters is no different. The filters contain a membrane with thousands of hollow fibers, which must be effectively secured in place to allow blood flow in and out of the membrane.
DOPAG has developed a special metering and mixing system for this task: high precision and reliability make the evomix DF system a perfect solution for potting of components with two-part polyurethane. The system is characterised by an interruption-free, continuous supply of material and can be integrated into a fully automated production line. The mixing head of the evomix DF is certified for use in cleanrooms.
