GHXLD partners with die casters that utilize the latest die casting machines and technology to deliver high-quality, on-demand parts to a wide variety of industries. Our offering focuses on the two leading types of die casting: hot chamber casting and cold chamber casting. Both types can produce parts with complex geometry, close tolerances, and robust mechanical properties.

Also known as gooseneck casting, the hot chamber die casting process is the most popular die casting process. 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.

With the cold chamber die casting process, the chamber remains at room temperature and does not have a holding pot of molten metal. Metal is melted in a separate furnace and deposited into the shot chamber through a pouring hole by hand with a ladle. In cold chamber die casting, the mold is connected directly to the shot chamber and does not utilize a plunger system. Instead, a ram forces molten metal into the mold and held under high pressure while the metal solidifies. This type of die casting is suitable for comparatively higher melting temperature materials such as aluminum.
