Zinc Die Casting/ Hot Chamber Die Casting

Also known as gooseneck casting, It is optimal for working with lower melting point alloys such as zinc, magnesium, and lead.  A holding pot is filled with metal and heated with hot chamber die casting until molten by an attached or built-in furnace. A feature of the hot chamber system referred to as the gooseneck forms a holding chamber within the pot and a nozzle-like pathway that connects to the injection cavity of the fixed half of the die. A plunger that sits above the chamber allows it to fill with molten metal from the holding pot. When the chamber is loaded, the plunger lowers and forces molten material up the gooseneck into the die cavity. The mold is held together under pressure while the metal cools and solidifies in the mold. Once the metal is cool enough, the dies open, and the casted piece ejects via ejector pins.
Zinc is the easiest to cast material among the die casting metals and is typically used in hot chamber processes. Molten zinc has exceptional casting fluidity and a lower melting point. Its strength and stiffness allow it to produce parts with thinner walls and highly detailed features and maintain tight tolerances. The low melting point of die casting zinc alloys means the die casted parts cool off and solidify more quickly, which results in the fastest production rates of the die casting materials.
Zinc is an all-around well-performing material due to its balance of mechanical and physical
