System for demolding materials obtained by means of the freeze-casting technique

A linear actuator is used to remove solid-state parts in low-temperature condition from the containers used as a mold for manufacturing parts using freeze-casting. The device allows pressure to be applied to the material to be removed, resulting in ejection. The displacement of the material is performed with controlled displacement speed, providing the achievement of defect-free materials. The system performing the ejection includes a source of compressed air, a pressure regulator filter coupled with a manometer, a directional valve, the linear actuator, a baton, a flow regulating valve, a fastening means, a metallic support and a chamber for receiving the cooled material.
