There are several different types of die casting, each with unique benefits. The two most common types of die casting are cold chamber die casting and hot chamber die casting.

cold room die casting (metallurgy):

In this type of die casting, a cold chamber machine is used to inject molten metal into the mold cavity. The machine is typically used to cast high melting point metals such as aluminum. The main advantage of cold chamber die casting is that it can be used with a variety of metals and reduces machine corrosion.

hot cell die casting (metallurgy):

Hot chamber die casting is the most popular method and is relatively faster than cold chamber die casting. Hot chamber die casting machines are used to perform this process in hot chamber die casting. The machine generally uses a metal with a lower melting point, such as zinc.

Both hot chamber die casting and cold chamber die casting have high precision. In addition, both processes are relatively fast and cost-effective.

Applicable Die Casting Materials:

When you’re ready to start a die casting project, one of the most important decisions you’ll make is choosing the right material. The material you choose must be able to withstand the high temperatures and pressures of the die casting process, as well as the requirements of the end use.

It is also important to select materials that are compatible with your chosen die casting operation. With so many factors to consider, it’s critical to work with an experienced die casting partner who can help you navigate the many options and make the best decision for your particular project.

However, aluminum, magnesium and zinc are the three most popular die casting materials because they are all strong and lightweight:

Aluminum: Aluminum is also highly resistant to corrosion, making it ideal for die-cast parts that are exposed to the elements.

Some of the most suitable aluminum alloys for die casting are:
Aluminum: 46100 / ADC12 / A383 / Al-Si11Cu3
Aluminum: 46500 / A380 / Al-Si8Cu3

Magnesium Alloys: Magnesium alloys such as AZ91D/AM60B/AS41B are also well suited for die casting due to their high strength to weight ratio. In addition, these alloys have good corrosion and wear resistance.

Zinc Alloy: Zinc, on the other hand, is an excellent conductor of heat and electricity, making it ideal for die-cast parts that require it.

Be rapidly heated or cooled.
