Release agents are of central significance in die casting technology.
Excerpt from the January 2020 Issue of Metalworking World by Fabio Boiocchi
Release agents affect the quality of the cast parts, the lifetime of molds and length of casting cycles. Release agents must be matched with the respective casting material and should meet high requirements in terms of economic efficiency and environmental compatibility.
Release agents are indispensable for the trouble-free production process in a die casting foundry. The most widely used release agents for die casting are water-based chemicals . They form a separating film between the casting mold and the casting material during the casting process and cool the casting mold, which has a strongly elevated surface temperature after a casting process. In the long run, such a temperature load – in the case of aluminum, for example, up to 500°C  – would cause severe wear of the mold. Therefore, release agents also protect the casting molds.Read More
