Types of Mold Die Casting

Cold Chamber Die Casting

In the process of Cold Chamber Die Casting, the metal undergoes melting within an external furnace, after which a ladle is employed for the transfer of the molten metal to the cold chamber machine. Suitable for alloys with higher melting points, offering precision and efficiency in the production of various components.

Hot Chamber Die Casting

Hot chamber die casting is characterized by melting metal within the casting machine itself. It is efficient for metals with lower melting points, like zinc. This method is favored for its speed and is suitable for producing small to medium-sized parts with intricate details.

Gravity Die Casting

Gravity die casting utilizes the force of gravity to fill the mold with molten metal. This method is renowned for its cost-effectiveness and suitability for large-scale production.
