Die Casting vs Mould Casting – What’s the Difference

Die Casting vs Mould Casting

Die casting and mould casting are two different ways of creating metal components. While they can both be used to produce the same types of products, there are some pros and cons that come with each method. In this blog post, we will discuss the advantages and disadvantages of die casting vs mould casting to help you make an informed decision about which is best for your project.

Die Casting Basic

Die casting is a process in which molten metal is injected into a die or mould cavity under high pressure. This process results in components that are precise in size, shape, and uniformity—all without needing to use any additional finishing processes. The main advantage of die casting is its ability to quickly produce large numbers of parts with minimal labour costs. Additionally, because the moulds used for die-casting are usually highly durable, multiple batches can be produced from one set of dies over many years with little maintenance required. The downside is that die-casting is more expensive than other methods due to the cost associated with creating the moulds and tools needed for production.

Mould Casting Basic

Mould casting is a manufacturing process in which molten metal is poured into a sand-based mould or ceramic shell mould. The castings created by this method tend to have fewer surface imperfections than those made with other methods due to the fine texture provided by sand-based moulds or ceramic shells. Additionally, mould castings also require less finishing work because they already have smooth surfaces when they come out of the mould. On the downside, mould castings tend to be slower and more labour-intensive than die casts because new sand moulds must be constructed for each batch produced—a process that can take weeks or months, depending on complexity. Additionally, mould castings tend to have less precise dimensions due to variations in sand density throughout the body of the moulded object.

Difference Between Die Casting and Mould Casting

  • Die casting is a process that involves injecting molten metal into a mould at high pressure.
  • Mould casting is a process that involves pouring molten metal into a mould and allowing it to cool.
  • Die casting is more expensive than mould casting.
  • Die casting produces parts that are more precise than those produced by mould casting.
  • Die casting can be used to produce parts with complex shapes.
  • Mould casting is best suited for low-volume production runs.


Both die casting and mould casting have their advantages and disadvantages when it comes to producing metal components. For high-volume production runs where precision and speed are essential, die casting may be your best bet; however, if you need complex shapes or intricate detail work, then mould casting may be your best option due to its superior surface finish quality and accuracy. Ultimately you will need to weigh all factors before making a decision, as there isn’t one clear winner between these two processes—it all depends on what your needs are for your specific project!
