What is die casting? – its advantages and disadvantages

What is die casting process?

Die casting is an automated casting process that forces liquid metal under high pressure (150 to 1200bar) into a mold cavity at a high filling speed. This type of casting offers uniform quality to the component produced. it is typically used when high volume of production and when quality, a consistent part is needed.

What is die casting

It is known as one of the quickest and most economical casting process. And can produce a hundred of thousands casting of same item using one mold, offering equal quality to the items.

The purpose of this article is to expose you to die casting, its advantages and disadvantages. In my previous articles centrifugal casting has been explained.

As earlier mentioned, die casting process is suitable for multiple and mass production of component. It is more better and faster than sand casting, due to the demolition of mold when bringing out the casting.

Advantages and disadvantages of die casting

Some advantages of die casting are mentioned above if can recall. Here are some to enlighten you more.

  • It offers accurate dimension and good surface finish, helping to eliminate post finishing
  • It can be fully automated
  • One of its greatest advantages is that, one mold can be repeatedly use for same production.
  • It offers fast production rate
  • Casting have long service life and close tolerance
  • It is economical
  • It is used for casting wide range of complex application

Here are some other advantages it offers to the casting properties

  • Good processing properties
  • Offers high electrical conductivity
  • It have high corrosion resistance
  • High strength and hardness
  • High thermal conductivity
  • Good EMF/RFI isolation


Despite the great advantages, die casting still offers some disadvantages that can be avoided and overlook. The following are:

  • High die cast
  • Gasses entrapped in form of porosity
  • Metals and alloys with high melting point cannot be applicable
  • Too long lead time
  • Smaller production runs may reduce cost-effectiveness
