Thanks to its amazing features, aluminium is a popular metal to be die cast for industrial purposes. Given its durability and resistance to corrosion, aluminium makes a great replacement for ferrous materials to use in the production of various parts. Find below an overview of aluminium die casting.
Is it subject to cold chamber or hot chamber die casting?
Generally, aluminium is die cast using either the cold chamber and hot chamber methods. Cold chamber process is more suitable for this metal as it has a high melting point. Since the aluminium gets molten in a separate furnace, the mould chamber remains cool, which makes it easier for it to resist the metal’s high temperature during casting. However, it’s worth mentioning that the cold chamber process lasts longer, being divided into two processes that take place one after another.
While having a higher risk of machine damage, the hot chamber process is still used for aluminium casting when the production rates have to be increased. If the customer needs a large amount of parts to be supplied in a short period of time, the manufacturer may choose the hot casting method to speed up production. But, in this case the customer has to assume the consequences related to the lower density and lower durability of the final product. Hot casting may be used to create aluminium parts that are not subject to extreme stress during use, so being slightly less durable doesn’t affect its lifespan and performance.
Advantages of aluminum die casting
Aluminium is widely used as an alternative to ferrous metals by aluminium die casting company in Malaysia and other global manufacturers. It is lightweight and durable at the same time, which allows it to reduce the weight of produced machinery and parts, while preserving their durability. Also, aluminium prides itself on high electricity and temperature conductivity and production cost-effectiveness. This metal’s die casting is defined by a smooth and neat finish and outstanding precision.
If it is cast in cold chamber conditions, it ends up to have a higher density, given the injection mechanism using more pressure to force the metal inside the cavity. In result, you get an even more durable product that performs better under stress, requires lower maintenance, and lasts longer. The nice thing about this highly conductive metal is that it’s industrially recyclable. That is to say, aluminium machines or parts that have suffered irreparable damage during use can be brought back to the die casting manufacturer, where the metal gets molten and die cast in a new shape.
Die cast aluminium parts find their use in a wide range of industries and they are found in many machinery and devices you use daily. From the construction of vehicles and building partitions to home use devices. For example, given its high heat conductivity, aluminium is popular in producing cookware, such as pots, pans, and roasting sets. Aluminium is also found in electronic devices, like laptops and smartphones, as well as in bikes which makes them lighter than expected and easier to maneuver.
