The Temperature in Die Casting Process(2)

In die casting process, material temperature and mould temperature will affect the quality of parts. Focusing on the temperature can help you to provide qualified products.

Usually the mould temperature needs to be maintained at about a third of the material temperature. However, it is a complex calculation to get the exact temperature for die casting process. It is a work finished by professional engineer.

Different material needs different temperature for die casting. Here are two examples to show you how does temperature affect the different material and maybe it can help you.

Aluminum is a common metal for die casting because it is light weight, durable and has good corrosion resistance. A360, A380 and A413 are aluminum alloy that people like most.

For Aluminum 380, for example, you’ll see a tensile strength of 48 at 75 degrees and a yield strength of 24. Get up to 212 degrees, and it’s 45 KSI (Kips Per Square Inch) tensile strength while the yield strength stays constant at 24. For Aluminum 390, yield strengths range from 41 KSI down to 18 KSI for 500 degrees.

Zinc is also popular in die casting industry. Die caster usually use Zamak 3, 5 and 7 zinc alloy for production.

For these alloys, a temperature of 75 degrees produces an average 40 KSI, while a temperature of 275 degrees produces an average KSI as low as 10. Other zinc alloys show similar yield strength decline with increasing temperature.
