An Insight into Magnesium Die Casting

It was during the industrial era that the scientific community and manufacturers worked hand in hand to create processes that could be used for mass production of products. Many new inventions and plenty of advanced technologies were developed during this period of time. These manufacturing processes have been fine-tuned and optimized over years in order to maximize production and reduce costs. One such technique that revolutionized the manufacturing industry is magnesium die casting.

In layman’s terms, die casting is a process that involves forcing hot molten metal into a mould and allowing it to cool. When the magnesium alloy cools, it takes up the shape of the cast. Then the cast can be removed to release the manufactured part. This method may seem to sound very simple, but there are lots of factors that the manufacturers have to be taken into consideration when the manufacturers set up the entire unit for magnesium die casting.

It is not just magnesium alloy that is used for die casting. A variety of non-ferrous metals such as zinc, aluminium, tin and their alloys are also used in this technique. The choice of the metal alloy and other manufacturing conditions depends on the process and the product. The casting time and the amount of material required depends on the die cast design and process flow. If properly planned and executed, the die casting process can be used to mass produce products without loss of quality or waste of raw material.

Magnesium die casting is preferred for many product manufacturing processes as it is lightweight yet strong. This alloy is used in the production of parts and components for automobiles, hand tools and scores of other appliances. This alloy is also preferred for processes in which the operating temperature is more than 120 degree Celsius. Even if the alloy is cast at such high temperature, its surface flatness and bolt tension is maintained. So, you will get superior quality results each time.

When compared to other casting metals, magnesium alloy offers greater corrosion resistance and better machining. Moreover, this metal alloy has high conductivity, superior dimensional stability and stiffness. So, manufacturers can use this metal alloy for processes that involve casting wafer thin wall products.

After magnesium die casting process is completed, the components can be painted or powder coated. However, the casts will require pre-treatment in order to ensure proper adhesion and smooth results.
