Specialized Products for the Thixomolding Process
In Thixomolding, the charge is in the form of metal chips that are fed to a heated barrel through a hopper. A screw within the barrel agitates the mix as it melts, giving rise to the globular grain structure. It also injects the semi-solid slurry 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. Chem-Trend die lubricants for these applications are able to regulate the solidification of the melt during filling, as well as resist erosion by the melt.
