The ceramic shell used is built around smooth patterns produced by injecting wax into a polished aluminum die. A 125 micro finish is standard, and even finer finishes are not uncommon. Investment castings contain no parting line because only one mold is used rather than two half molds (such as in the case of sand casting). Standards for surface As specified in , the yield strength (YS), the ultimate tensile strength (UTS) and the elongation to fracture (EL%) in as-die-cast condition are, respectively, 140 MPa, 240 MPa and less than 1% for the most high-pressure die-cast (HPDC) alloys, while these are around 90 MPa, 170 MPa and in the range 1–2.5% for the main gravity die-cast (GDC Here are the characteristics of aluminum alloys: Lightweight: Aluminum alloys have low densities, making them lightweight and ideal for applications where weight is a critical factor. Corrosion Resistance: The surfaces of aluminum alloys form a natural oxide layer that protects against corrosion in many environments. Founded in 1919 and reportedly one of the oldest die casters in the U.S., Twin City Die Castings Co. maintains three facilities: one in Minneapolis (company headquarters) where it casts aluminum only; one in nearby Monticello, Minn. (shown above), where it casts magnesium exclusively; and another in Watertown, South Dakota, where it also casts Aluminum die casting is a metal-forming process that allows for the creation of complex aluminum parts. Ingots of aluminum alloy are heated to very high temperatures until they are entirely molten. To find out more about our aluminum die casting service, or other capabilities, contact us online today.
