Nitinol Pneumatic Cylinder Replacement

This long stroke, high speed, prototype SMA actuator was designed for Sony to remove DVD’s that did not pass quality control from an assembly line. Mineral oil is used in the body of this actuator to enhance cooling of the Nitinol. This actuator features 8″ of 0.010″ diameter HT Flexinol. It operated at 28 Volts which is typical of industrial equipment. Our Nitinol Actuation Model showed that enhanced cooling would be required to meet the one second recovery time as required by the Sony spec.
