Advanced Lubricants to Address Rheocasting Challenges

In Rheocasting, liquid alloy is gradually cooled until it reaches a semisolid state. Agitation is provided either mechanically or electromagnetically to stimulate nucleation and promote globular grain formation. It is then placed in the sleeve and injected into the die cast machine.

Since the melt is partly solidified, proper thermal control of the die is essential to ensure proper filling of the die cavity. In some alloys the solidified particles can also be quite abrasive. The die lubricants developed for these applications by Chem-Trend are designed to regulate the solidification of the melt during filling and to resist erosion by the melt, as well.
