High Pressure Die Casting Advantages & Disadvantages

High Pressure Die Casting Advantages & Disadvantages

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

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

Should you require giant volumes of advanced elements, high pressure die casting will deliver what you want with speed and precision.

The casting cycles for high pressure die casting are extremely quick when compared to other methods, as the molten metal solidifies in mere seconds. This assists the process in being extraordinarily cost-effective when it involves mass production.

High pressure die casting also lends itself well to components that are thin walled. Wall thicknesses produced by high pressure die casting will be as low as 1mm (relying on the size of the part), making it far more efficient than different processes when it involves creating a exact casting that can be extraordinarily lightweight.

In addition, high pressure die casting creates a really smooth surface. So, if it's good to apply an additional finish, you’ll have an incredible primer for coatings to be utilized directly within the subsequent phase.

The primary disadvantage of high pressure die casting is its porosity – however an evacuated chamber and different strategies could reduce this.

Due to the presence of these pores (containing entrapped gases), elements created by means of high pressure die casting can’t often be totally heat treated. This would, unfortunately, lead to the formation of surface blisters.

High pressure die casting is also known to have high start-up costs, but this isn’t strictly a disadvantage, relying in your perspective. The initial tooling cost may be higher than different methods, however the long casting run that this process enables may also facilitate a low unit price alongside the aforementioned high-volume production.

Should you think that high pressure die casting is the fitting process to suit your closing application, you’ll need to discover a reliable partner to produce these components. However why do you have to choose us?

Firstly, it’s necessary to know that the surface area and weight of a die cast might be limited by the locking force of the machine used. We mitigate this restriction by using high pressure die casting machines with locking forces of between 220 and 530 tonnes.

Higher but, all of our machines function computerised real-time shot control, automated ladling, die-spray, automated casting extraction and cooling - providing repeatability and productivity.

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