The high pressure die casting process is a fast, precise method of creating components made from aluminium or zinc. It’s favoured, in particular, by advanced industries which have very specific necessities 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 into a hardened steel mould and allowing it to solidify under pressure earlier than ejection.
WHAT ARE THE ADVANTAGES OF HIGH PRESSURE DIE CASTING?
If you happen to require large volumes of complicated elements, high pressure die casting will deliver what you need with speed and precision.
The casting cycles for high pressure die casting are extraordinarily short when compared to other strategies, 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 additionally lends itself well to components which are thin walled. Wall thicknesses produced by high pressure die casting will be as low as 1mm (relying on the scale of the element), making it far more effective than other processes when it involves creating a exact casting that is also extraordinarily lightweight.
In addition, high pressure die casting creates a really smooth surface. So, if you must apply an extra finish, you’ll have an awesome primer for coatings to be utilized directly in the subsequent phase.
WHAT ARE THE DISADVANTAGES OF HIGH PRESSURE DIE CASTING?
The main disadvantage of high pressure die casting is its porosity – but an evacuated chamber and other techniques may reduce this.
Because of the presence of these pores (containing entrapped gases), parts created via high pressure die casting can’t often be totally heat treated. This would, sadly, 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 on your perspective. The initial tooling value could also be higher than other strategies, however the lengthy casting run that this process enables may facilitate a low unit price alongsideside the aforementioned high-volume production.
If you think that high pressure die casting is the appropriate process to suit your closing application, you’ll need to find a reliable partner to produce these components. However why should you select us?
Firstly, it’s vital to know that the surface space and weight of a die cast will 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, computerized ladling, die-spray, computerized casting extraction and cooling - providing repeatability and productivity.
In addition, other foundries could only offer their companies for high volume orders, claiming that prolonged set-ups make the process prohibitive to small runs.
