The manufacture of medical devices always requires a particular level 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. Material discharge 100 ml - 900 ml / min, depending on mixing ratio and viscosity Mixing ratio 100 : 20 - 100:80, volumetric Mixing system Static-dynamic ■ 2K valve ■ Plastic mixer tube Material supply 90 and 120 l material pressure vessels Viscosity range 50 - 80.000 mPas, with material pressure vessels Material properties Unfilled, filled, abrasive
