Aluminium Diecasting Vs Pressure Diecasting

Aluminium die casting and pressure die casting are two of the main ways of casting a metal object. But which one is best for your project? Here, you will find an overview of the similarities and differences between aluminium die casting and pressure die casting and an explanation of the relative benefits of each method.

Benefits of aluminium die casting vs pressure die casting

These are two different processes and as a result, each has different advantages and disadvantages. Aluminium die casting involves pouring molten aluminium (sometimes mixed with another appropriate alloy) into a mould and then allowing it to cool. Pressure die casting, on the other hand, involves injecting the molten metal into a steel mould at high pressure and high speed. Then, the metal is extracted automatically. Pressure die casting is split into two forms: high pressure die casting and low pressure die casting. High pressure die casting is used for small, intricate parts (often parts that have very precise geometry). Low pressure die casting is more suitable for making larger parts.

What are the benefits of aluminium die casting?

There are many benefits to aluminium die casting. It is one of the most cost effective casting methods, and it also has the advantage that aluminium is fully recyclable (it can be melted down and used again without losing any of its properties). Aluminium is also both durable and light weight: a winning combination. Finally, aluminium die casting is highly suitable for jobs with medium to high production, as once the mould has been made, you can use the aluminium die casting process to create many metal objects in a short space of time.

What are the benefits of pressure die casting?

Pressure die casting is also a very cost effective casting method, and, similarly to aluminium die casting, it is also highly suitable for large jobs that require a large number of products to be made in a tight time frame. One way in which pressure die casting is often said to be superior to aluminium die casting is the fact that it provides a more precise finish, and so it is great for complex moulds. In addition, aluminium die casting can be used with thinner, lighter moulds which is useful for companies that want to cut costs on the materials that they use for their moulds.

The bottom line: aluminium diecasting or pressure diecasting?

Both of these die casting methods will provide you with a uniform, homogenous set of products in a short space of time. If you are looking for an intricate finish, it may be worth going for the pressure method. But, if you are keen for a fully recyclable material within your moulds, then opting for aluminium is the smart choice. If you do opt for the pressure die casting method, you will also need to choose between high pressure die casting (perfect for small, intricate objects) and low pressure die casting (more suitable for creating larger objects).
