What do you know about die casting?
Oct. 22, 2021
As a Casting Supplier, I take you through die casting. Die casting is used to produce a wide range of products that can be found in almost any industry or vertical you can think of.
As with any other metal manufacturing process, die cast products are only as good as the metal used in their production. The source metal will affect the overall quality, durability and aesthetic appearance of the finished product.

What is Die Casting?
Die casting is a metal manufacturing process that involves pressing molten metal under high pressure into a reusable metal mold. Die casting creates metal parts that are dimensionally accurate, well-defined, and have a smooth or textured surface.
Commonly used in the manufacturing industry, die casting is a casting process that involves forcing molten metal through the cavity of a pre-shaped mold. Base metals such as zinc, aluminum, copper, magnesium and lead are first heated until they achieve a molten state. The newly molten metal is then forced into a pre-shaped mold using pressure. Once the molten metal has cooled and hardened, it's removed from the mold.
The two main die casting processes.
Hot Chamber Die Casting
Molten metal is forced through the cavity of a pre-shaped mold using pressure. The defining characteristic of hot-chamber die casting is that metal is heated inside the casting machine rather than a separate machine or furnace. Hot-chamber die casting is a relatively fast process. While not suitable for metals with a high melting point, it’s ideal for zinc alloys, tin alloys and lead alloys.
Cold Chamber Die Casting
Based on its name, you may assume that cold-chamber die casting involves forcing cold metal through the cavity of a mold, but this isn't necessarily true. Cold-chamber die casting still requires the use of molten metal that’s forced into a mold. The difference between these two processes is that hot-chamber die casting heats metal inside the casting machine, whereas cold-chamber die casting involves heating metal in a separate furnace and then transferring the newly molten metal into the casting machine.
Custom Die Casting
With cold-chamber die casting, metal is first heated to achieve a molten state in a separate furnace. The molten metal is then transported to the casting machine where it's fed into the machine'S chamber. The machine uses a pressurized plunger to force the molten metal into the cavity of the mold.
Certain types of metals — those with a high melting point — can only be processed using cold-chamber die casting. The high temperatures required to achieve a molten state for metals such as aluminum, magnesium and copper means a separate furnace must be used, which is why some manufacturers choose cold-chamber die casting over hot-chamber die casting.
