Abstract

A loader assembly for a TEM machine having a retractable arm that is moveable between a retracted position and an extended position. A hoop portion of the retractable arm also moves between the retracted position and the extended position. A lower closure for holding a part to be processed in the TEM machine is removably positioned in the hoop portion. A ram piston of the TEM machine is movable between a load position and a process position. When the ram piston moves from a load position to a process position the ram piston contacts the lower closure and extends through the hoop of the retractable arm to move the lower closure to the process position. A thermal chamber receives the lower closure when the ram piston moves to the process position.
