Why Rheocasting?
Rheocasting has the advantage of a high solid fraction that enables:
— Very long flow length by its thixotropic characteristics.
— Castings with very low porosity levels due to the laminar flow.
— Easier after feeding to avoid shrinkage porosity.
— Use of non-eutectic allows to reach higher properties in castings from a high pressure die cast process.
Advantages With Rheocasting
— High thermal conductivity
— Extreme thin-walled castings
— Excellent flowability
— Weldable
— Smaller HPDC machines
— Laminar flow gives minimal amount of defects
— Decreased CO2 footprint
Sustainable Castings
In today’s business, CO2 footprint is an essential part towards the global net-zero target.
Silicon is the major CO2 contributor (approx 40%) in production of secondary alloys.
Rheocasting allows the use of a new set of alloys that contain less Si.
Due to the thixotropic behaviour of a slurry, Rheocasting does not require Si inside the alloy to have a good castability as conventional HPDC does.
With Rheocasting, you can reduce the CO2 footprint by using a secondary alloy with low Si content for a low CO2 emission or design a lighter part with a more competent alloy.
So, by using alloys with lesser Si, we will contribute in the work to reach the global targets.
