A composite material structure can be constructed using an airforming process that includes filling the inflated support mold with a fluid structural material and allowing the fluid structural material to harden within the support mold. Additional steps can include inflating the support mold with a first fluid, forming fluid escape outlets in the support mold, and removing the support mold after allowing the fluid structural material to harden. The first fluid can be air, the support mold can be a fiberglass resin, and/or the fluid structural material can be a concrete composite material. Fluid can escape through the fluid escape outlets during the filling. The finished structure can include multiple structural components formed from a homogenous concrete composite material and having curved and non-planar geometries. The concrete composite material can include aluminum alloy fibers.

A pressure die casting mold for producing a casting which is part of an integral toilet having a body, a water ring, and a tank, wherein the casting, as an integral component, includes the water ring and the tank which is open on the upper side. The pressure die casting mold is composed of at least five molded parts which are interconnectable in a releasable manner, namely of a base part, two side parts having in each case one half of a front wall, a rear wall, and a cover part. The molded parts delimit a cavity which corresponds to the outer shape of the casting. A wedge element, which at least in portions delimits the inner shape of the water tank, is provided on the base part.

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.
