High Pressure Die Casting Advantages & Disadvantages

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

HOW DOES HIGH PRESSURE DIE CASTING WORK?

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

WHAT ARE THE ADVANTAGES OF HIGH PRESSURE DIE CASTING?

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

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

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

In addition, high pressure die casting creates a very smooth surface. So, if you need to apply an extra end, you’ll have a great primer for coatings to be applied directly within the next phase.

WHAT ARE THE DISADVANTAGES OF HIGH PRESSURE DIE CASTING?

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

Because of the presence of these pores (containing entrapped gases), elements created by way of high pressure die casting can’t often 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 costs, but this isn’t strictly a disadvantage, depending in your perspective. The initial tooling value could also be higher than different methods, but the lengthy casting run that this process enables can even facilitate a low unit value alongsideside the aforementioned high-volume production.

When you think that high pressure die casting is the precise process to suit your final application, you’ll must find a reliable partner to produce those components. But why do you have to choose us?

Firstly, it’s necessary to know that the surface area and weight of a die forged might 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.

Better yet, 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 may only offer their providers for high volume orders, claiming that prolonged set-ups make the process prohibitive to small runs.
