Hot Chamber vs. Cold Chamber Die Casting

Die casting is an efficient manufacturing process for mass production of various shapes of parts, which have become common items in our homes and workplaces. Die casting provides a reliable process with smooth surface and high quality without any additional polishing or tools.

The two most common methods of die casting are hot chamber and cold chamber. Understanding the difference between these two options can help you evaluate and collaborate with part manufacturers. Let's take a look at each die casting and understand their advantages and disadvantages.

Overview of hot chamber die casting

Hot chamber die casting uses the same process as mentioned earlier-molten metal is forced through the cavity of the preform mold under pressure. The main feature of hot chamber die casting is that the metal is heated inside the casting machine rather than in a separate machine or furnace.

The hot chamber casting machine is also known as the gooseneck machine, which is characterized by a built-in furnace in which the metal is heated to reach a molten state. They use hydraulic pistons to drive molten metal out of the furnace and into the mold. Hot chamber die casting is a relatively fast process, with a typical cycle lasting only 15 to 20 minutes. Although not suitable for high melting point metals, it is ideal for zinc alloys, tin alloys and lead alloys.

Overview of Cold Chamber Die Casting

Based on its name, you might think that cold chamber die casting involves forcing cold metal through the cavity of the mold, but this is not necessarily true. Cold chamber die casting still requires the use of molten metal that is forced into the mold. The difference between the two processes is that the hot chamber die casting method heats the metal in the casting machine, while the cold chamber die casting method heats the metal in a separate furnace and then transfers the newly melted metal to the casting machine.

For cold chamber die casting, the metal must first be heated in a separate furnace to reach a molten state. The molten metal is then transported to the casting machine and then sent to the casting machine room. The machine uses a pressurized plunger to press molten metal into the mold cavity.

Certain types of metals (metals with high melting points) can only be processed by cold chamber die casting. The high temperatures required for metals such as aluminum, magnesium and copper to reach a molten state means that separate furnaces must be used, which is why some manufacturers choose cold chamber die casting instead of hot chamber die casting.

Below is some questions you may want to know:

Questions: How can we know the chemical component of your products is according to our request?

Answers: When we offer samples or batch parts, we will also send you our material list from our material factory, it shows more detailed.

Questions: How to guarantee your final size can meet our drawing request?

Answers: we will make moulds according to your 3D drawing. And we also do sampling when batch production start, to make assure the final dimension can meet your request.

Questions: Generally, how do you packing the goods?

Answers: normally, for inner package: the goods is nude, for outer package: carton + plywood. If you have special request for inner or outer package, pls indicate it when you send us new inquiry.

Questions: If we find the defect products exist in the batch parts, how to do?

Answers: Yes,your caution is very good, in fact, when batch production, we need do sampling. Before shipment, we also do testing to make sure the quality is ok. If you found several defect product exists, pls take photos and send your quality feedback, we will check and send you quality products. But pls be assured that our products is qualified, unless caused by the worker's mistake to place.
