Brass die casting is opted by an Original Equipment Manufacturer in automobiles since brass is a corrosion free alloy. Semi Solid Metal casting, on the other hand, is a technique that clubs the pros of both liquid metal casting and metal forging. The Semi Solid Metal casting process is a variant of die casting and is used to mold casted alloy featuring thin wall components of up to 2 millimeters thick. In this method, the selected non-ferrous metals such as copper, aluminum, or magnesium get cast inside a cool chamber, instead of a hot chamber.
The Casting Process
In Semi Solid Metal die casting, metal is melted at a low temperature of, say, 10 percent, until the metal reaches a 30 to 60 percent liquid state. The chamber then exerts applied force onto the alloy until the separations are formed as per the discretion of engineers. The engineers pay heed to maintain uniformity in the process and give a quality in cast components just as the liquid metal solidifies gradually.
Alloy Types Used in Semi Solid Metal Casting
Engineers say that non-ferrous dies, including brass, graphite, stainless stee,l and other non-ferrous metal can be used in Semi Solid Metal die casting. Since the process requires lower temperature and pressure, expensive metals are not used in general. Engineers ensure better control by handpicking a die of their design preference, by using chambers and molding metal to the OEM’s set preference. The process, also known as Thixocasting and Rheocasting, is used for aluminum alloys alongside thixomolding for magnesium.
Application for the OEMs in Mexico
The Semi Solid Metal die casting process is ideally opted by OEMs who seek die cast components in bulk in either Mexico or America. The process molds the metal including brass and helps OEM bag cast components such as a suspension mount, engine block, or an oil pump filter housing in automotive, whereas the same is used for casting camera body and castings in computers. Mexican OEMs make full use of their large-scale production facilities and the die casters only aid them being an ancillary service.
Semi Solid Metal casting also gives sample prototypes to an American OEM packaged to precision by the ancillary unit. In a nutshell, the Semi Solid Metal die casting process gives great tensile strength and ultra-thin wall separations for automobile components.
