Die Casting


The die casting method or process can be applied to a wide range of metals that can be molded and utilized for several other products. Since metal is the main variable in creating die casts, most products undergoing die casting are considered to be strong, bearing long service lives, easy access to building products with accurate measurements and all the other advantageous features metal can bring to a product. Die castings undergo a complicated process but is mostly automated. There is a wide variation of metal that can be made into die casts like aluminum, zinc, copper and etc, but the metal depends on the desired finished product. In the diecasting process, metal, in its melted form, is poured into a mold cavity which is shaped like the finished product.

Today, almost everything we use is made out of metal. What we don’t know is how the process takes place in creating, molding and designing a by-product of different kinds of metal. Unlike clay pots where clay is molded by human hands on a potter’s wheel, metal cannot go through the same method – most probably because metal isn’t the easiest to mold nor is it the best idea to touch either especially when metal is all hot and liquid-like. These metal items we use are molded through the process of diecasting.

While diecastings are in high demand and have lots of advantages there are also some disadvantages that diecasting companies have to consider.

The main disadvantage of diecasting is the fact that the whole process is very expensive. The initial cost of the whole process – machines, metal – anything required to die cast are quite expensive thus volume manufacturing has to be done. This way, manufacturers are producing more by-products and saving money. Diecastings are also limited only to high fluidity metals so choosing the right metals for a specific product has to become part of the daily process. Casting weights also have limitations – casts must not be less than 30g and yet, not more than 10kg. Aside from weight limitations, casting also limits on the thickness and size of the die cast product, only allowing not more than 600mm or 24 inches and the thickest part must not exceed 13mm or 0.5 inches.

Having this in mind would mean careful planning for financial and material resources. It is important to choose a trusted die casting manufacturer who knows the best way to customize production process for the advantage of the part or product they intend to make.
