Die Casting Services
Hot Chamber Die Casting
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.
Cold Chamber Die Casting
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.
Capabilities for Die Casting Success

Various materials are used in the die casting process, including metals and alloys. Some of the premium materials commonly used in die casting parts include:
Magnesium: Die casting often makes use of magnesium since it is both light and sturdy. Wheels, steering components, and electrical housings are only some of the products to which it is put to use.
Zinc: Metal die casting frequently employs zinc because of the metal’s strength and malleability. The company manufactures a variety of products, including hardware and auto parts.
Steel:
Steel is a strong and long-lasting metal used in die casting. It is used to manufacture various items, including automotive and industrial machinery components.
Copper:
Copper is a popular metal for die casting because it is durable and electrically conductive. Connectors and switch housings are only two of the many products it makes for the electronics and electrical sectors.
Aluminum:
In the die casting industry, aluminum is commonly utilized because of its low cost, high strength, and high corrosion resistance. It manufactures various components, including those for automobiles and electronic enclosures.
