The Dutch enterprise CIREX – the most important wax investment foundry throughout the world – stakes on the 4-column press systems from TOX PRESSOTECHNIK for the sizing and aligning of castings.When it comes to castings produced in a wax investment process, the Dutch specialist CIREX is the first-class name in the international field! The wax investment process is mainly used for the production of costly formed, i.e. complex components. Due to the relatively low tool cost, this process is already profitable with small quantities. For this process, the model gets first founded in wax. For major series, the wax model can also be made by injection moulding and provided then, as a kind of sealing, with a ceramic layer. Thereafter the casting moulds (smaller parts are also called clusters) are put into the autoclave. There the wax gets melted and the ceramic mouldings remain and are subjected to a sinter/baking process in another oven. Thereafter the correspondingly liquefied metal is cast into the ceramic mouldings. After cooling, the ceramic layer is knocked off and the castings close to contour and shape remain. ..... |
