We use 50% less material compared to cold chamber die casting. We inject a semi-solid slurry directly into the multi-cavity mold, without hot runners with precise dosing of the slurry. We are able to mold net shape parts with a wall thickness of about 1 mm.
We do precise solid content control in a semi-solid slurry by precise temperature control using first real-time x-ray feedback control loop. We are able to mold net shape parts with a wall thickness of about 1 mm. We are also able to produce ultra large surface area parts by means of multiple injectors!
Our process is totally sealed, therefore we only use 29% of the energy compared to cold chamber die casting (0.67 KJ/g vs. 2.3 KJ/g). The temperature of the semi-solid slurry is between 480°C and 580°C. Compare this to a cold chamber die casting temperature of between 680°C and 700°C. We also recover and recycle the heat of the mold to pre-heat input alloy chips.
Our process is totally sealed. We use a small amount of Argon to seal our process against the enviroment, instead of a large amount of SF₆ or SO₂ which is required as a fluid metal cover gas in hot and cold chamber die casting. Cover gas used in old processes has negative side effects, such as depleting the ozone layer. In our sealed process, there are no emissions.
