Applications of Precision Steel Casting

7. Ejectors In some cases, ejector pins or plates are included to assist in removing the finished part from the die. They help ensure that the stamped component is expelled without damage, which is especially important in high-volume production.

After the molten metal cools and solidifies, the next step is to remove the mold. This is often accomplished by breaking the sand apart, revealing the cast object. The sand can typically be reused for future molds, making sand casting an efficient process in terms of material usage. However, the casting might require additional post-processing to achieve the desired surface finish and dimensional accuracy. This can include machining processes, grinding, or sandblasting.

Die cast zinc alloys are primarily composed of zinc, typically combined with small percentages of aluminum, copper, magnesium, and other elements. Common zinc die casting alloys include Zamak, which consists of zinc, aluminum, magnesium, and copper, among others. These alloys are favored for their excellent casting characteristics, including fluidity, strength, and resistance to corrosion.
