Semi-solid die casting technology currently has two forming processes: rheological forming process and thixoforming process. The former is to send the liquid metal into a specially designed injection molding machine barrel, which is sheared by a screw device to cool it into a semi-solid slurry, and then die-cast.
The latter is to feed the solid metal particles or scraps into the screw injection molding machine, and under the conditions of heating and shearing, the metal particles are converted into slurry and then die-casted into shape.
At present, the semi-solid metal casting used in domestic and foreign industries mainly refers to thixocasting, which is widely used in the body frame structure.
As a precision forming method, thixocasting has high strength of the workpiece after forming, and can realize one-time forming of complex shapes. It can realize mass production of various non-cutting or very little-cutting parts and reduce the number of parts.
The above is the introduction of precision die-casting technology. I hope to bring help to friends in need. If you want to learn more about aluminum alloy casing, please continue to pay attention to our website, we will update it regularly.
