Die Casting vs Gravity Die Casting – What’s the Difference

Die Casting vs Gravity Die Casting

Have you ever wondered what makes a diecasting process different from a gravity diecasting process? Both processes are used to create metal parts, but they are not the same. In this blog post, we will discuss the differences between die casting and gravity die casting so that you can decide which method is best for your project.

Die Casting Process

The diecasting process involves creating parts using a special type of mould. This mould is made up of two halves and is filled with molten metal under high pressure. Once the metal cools, it hardens and takes on the form of a mould. The process itself is relatively quick and cost-effective, but it does require specialized machinery and trained personnel to operate it safely and efficiently.

Gravity Die Casting Process

Gravity die casting, also known as permanent mould or sand casting, is a more traditional approach to creating metal parts. Instead of using pressure like in the diecasting process, gravity diecasting uses gravity to fill the moulds with molten metal. This method requires less specialized equipment than die casting, but it’s typically slower and more labour-intensive since each part needs to be manually inspected for defects before being released for sale or use.

Benefits & Drawbacks of Each Method

When deciding between these two processes, there are both benefits and drawbacks to consider. Die casting offers quick turnaround times and cost savings due to its automated nature, but it’s not suitable for all projects because of its high upfront cost. Gravity die casting may take longer to complete, but it can be cheaper in certain applications since it requires less specialized equipment. However, because each part must be hand-inspected before being released for use or sale, this can add additional costs depending on production volume.

Difference Between Die Casting and Gravity Die Casting

  • Die casting is a process that involves injecting molten metal under high pressure into a mould cavity.
  • Gravity dies casting is a type of die casting that uses the force of gravity to fill the mould cavity.
  • Die casting is typically used for small, intricate parts, while gravity dies casting is typically used for larger parts.
  • Die casting can be done with a variety of metals, including aluminium, brass, and bronze, while gravity dies casting is typically done with aluminium.
  • Die casting is typically faster and less expensive than gravity die casting.
  • Gravity die casting typically results in a higher quality part than die casting.


In conclusion, understanding the differences between diecasting and gravity diecasting is important when deciding which method is best for your project requirements, whether it be faster turnarounds or cost savings due to its automated nature versus lower upfront costs but potentially higher labour costs due to manual inspection requirements, respectively. Ultimately weighing out your options carefully should help you make an informed decision about which process (or combination) suits your needs best!
