The Filabot EX2 system is our mid-level extrusion system. The EX2 features a three-stage extrusion screw made from hardened and polished high-carbon steel. This proprietary, patent-pending screw is designed to pressurize plastics during the extrusion process, assisting in diameter control and boosting the overall output. The mixing capability of the screw is enhanced by the utilization of a progressive compression section, which applies shear force between the polymer and the barrel wall. The EX2 also features extrusion speed control. The speed control board includes an automatic, variable voltage control module that is engineered to regulate the precise RPM of the screw as forces fluctuate in the extrusion process. When used with the Filabot Spooler, tolerances of +/-0.05mm can be achieved at a rate of 2 lbs an hour.
