American Kuhne introduced its new Modular Micro Extruder at the recent MD&M West Exhibition in Anaheim, CA. American Kuhne ran a Pebax 6333 micro tubing system that included their new 12 mm Modular Micro Extruder with servo drive and pressure control. This extruder provides the versatility to quickly and easily change barrel and screw diameters and feed section geometry configurations – allowing for fast product change overs and thorough bare metal cleanouts.

The new modular micro extruders are available in 12 mm, 16 mm and 19 mm barrel/screw sizes and are suitable for medical device and pharmaceutical applications. Very low output volumes can be achieved down to 125 grams/hr using standard size pellet shapes and granules. Typical resins for micro catheters are processed such as Pebax, Nylon, and Polyurethane, high temperature polymers such as PEEK and FEP and Bioresorbable polymer formulations such as PLA. Complete micro extrusion systems are available for the production of tight tolerance medical tubing, co-extruded tubing, fine wire jacketing, filaments and solid dosage forms.

According to Steve Maxson, Vice President of Extrusion Systems at American Kuhne, “Micro extruders allow for a short residence time in the barrel, which helps to minimize thermal degradation especially compared to traditional size extruders running at very low screw speeds. A shorter residence time protects the molecular weight of the material and ultimately the physical properties of the end product that it is use in. This is especially important for developers of medical devices, dissolving oral dosage forms and drug-eluting devices.”

Significant investment and product development by American Kuhne has resulted in a comprehensive “pipeline” of seamlessly integrated precision micro extrusion equipment including Modular Micro Extruders, AKcess touchscreen control systems, AK-u-Tube™ Spiral Flow Crossheads, AK-u-Cool™ Precision Cooling Tanks and AK-u-Pull™ Combination Servo Puller/Cutter controls.
