Processing advantages of semi-solid die casting

Semi-solid die casting is a new type of metal forming process in the world, which can be quickly injected into liquid metal to make the metal after mold forming have high strength and strong stiffness. It can be widely used in aviation, automotive, communications, electronic appliances, instruments, medical and other high application industries or industries requiring "high quality, high efficiency, energy saving and environmental protection".

Compared with ordinary liquid casting, semi-solid casting has many obvious characteristics: the solidification shrinkage of castings is reduced, the size accuracy of castings is high, the appearance quality is good, the machining amount is reduced, and even no machining allowance castings can be obtained; The columnar crystals and coarse dendrites in conventional castings are eliminated, and the castings have fine structure, compact, uniform distribution, and no macrosegregation. The metal filling is smooth, no turbulence, no splash, and the filling temperature is low, extending the life of the mold; Simplify the casting process, reduce energy consumption, improve working conditions, due to the fast solidification speed, high productivity; Improve the mechanical properties of castings.

Therefore, we can see that the metal processing method of semi-solid die casting can not only make the metal products have the characteristics of high density, high strength/stiffness, high precision, fine surface, corrosion resistance, no pollution, etc., but also rapid molding, reducing the time of production. The semi-solid casting components are rheological casting and thixotropic casting. We use the most advanced rheological casting with short process flow, high production efficiency.
