High Pressure Die Casting Advantages & Disadvantages

The high pressure die casting process is a fast, precise methodology of making components made from aluminium or zinc. It’s favoured, in particular, by advanced industries which have very specific necessities over look, dimensional tolerances and lightweight components.


High pressure die casting provides the shortest route from molten metal to completed element, by injecting the molten metal into a hardened steel mould and allowing it to solidify under pressure earlier than ejection.


In the event you require giant volumes of complicated elements, high pressure die casting will deliver what you want with speed and precision.

The casting cycles for high pressure die casting are extraordinarily quick when compared to other strategies, as the molten metal solidifies in mere seconds. This assists the process in being extraordinarily price-efficient when it comes to mass production.

High pressure die casting additionally lends itself well to elements which are thin walled. Wall thicknesses produced by high pressure die casting might be as little as 1mm (depending on the size of the part), making it far more efficient than other processes when it involves creating a precise casting that is also extremely lightweight.

In addition, high pressure die casting creates a very smooth surface. So, if you should apply an additional finish, you’ll have an excellent primer for coatings to be applied directly in the subsequent phase.


The primary disadvantage of high pressure die casting is its porosity – but an evacuated chamber and different techniques might reduce this.

Due to the presence of those pores (containing entrapped gases), parts created by way of high pressure die casting can’t usually be fully heat treated. This would, unfortunately, lead to the formation of surface blisters.

High pressure die casting can be known to have high start-up prices, however this isn’t strictly a disadvantage, relying on your perspective. The initial tooling value could also be higher than different strategies, however the long casting run that this process enables can also facilitate a low unit cost alongsideside the aforementioned high-quantity production.

Should you think that high pressure die casting is the correct process to suit your closing application, you’ll must find a reliable partner to produce these components. However why must you choose us?

Firstly, it’s important to know that the surface space and weight of a die solid will be limited by the locking force of the machine used. We mitigate this restriction through the use of high pressure die casting machines with locking forces of between 220 and 530 tonnes.

Higher yet, all of our machines characteristic computerised real-time shot management, computerized ladling, die-spray, computerized casting extraction and cooling – providing repeatability and productivity.

In addition, different foundries might only supply their services for high volume orders, claiming that lengthy set-ups make the process prohibitive to small runs.
