Dust extraction of die casting machines when processing aluminum, zinc or magnesium

During series production of thin-walled components made of non-ferrous metal, molten casting metal is compressed under high pressure and at high speed into a metallic mold. In order to achieve an easy separation of casting and mold, and also to ensure surface quality, the molds are sprayed with a release agent. The molds are additionally lubricated at critical points. Because of the heat generated during the filling of molten metals, these release agents evaporate,  burn and partially rise as smoke fumes with thermal air currents.

Capturing, extracting and separating the dust/fumes is mandatory. The amount of air to be extracted depends on the size of the machine and its design (cold chamber or hot chamber).
