High Pressure Die Casting Advantages & Disadvantages
HOW DOES HIGH PRESSURE DIE CASTING WORK?
High pressure die casting provides the shortest route from molten metal to accomplished element, by injecting the molten metal into a hardened steel mould and allowing it to solidify under pressure before ejection.
WHAT ARE THE ADVANTAGES OF HIGH PRESSURE DIE CASTING?
In the event you require massive 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 short when compared to other strategies, because the molten metal solidifies in mere seconds. This assists the process in being extremely value-efficient when it comes to mass production.
High pressure die casting also lends itself well to components which are thin walled. Wall thicknesses produced by high pressure die casting will be as little as 1mm (depending on the scale of the component), making it far more effective than different processes when it comes to creating a exact casting that is also extraordinarily lightweight.
In addition, high pressure die casting creates a very smooth surface. So, if you should apply an additional finish, you’ll have a fantastic primer for coatings to be applied directly in the next phase.
WHAT ARE THE DISADVANTAGES OF HIGH PRESSURE DIE CASTING?
The main disadvantage of high pressure die casting is its porosity – however an evacuated chamber and other methods may reduce this.
As a result of presence of these pores (containing entrapped gases), components created through high pressure die casting can’t normally be absolutely heat treated. This would, unfortunately, lead to the formation of surface blisters.
High pressure die casting can also be known to have high start-up prices, but this isn’t strictly a disadvantage, relying in your perspective. The initial tooling price could also be higher than other methods, but the long casting run that this process enables also can facilitate a low unit price alongside the aforementioned high-quantity production.
Should you think that high pressure die casting is the precise process to suit your last application, you’ll must find a reliable partner to produce these components. However why must you select us?
Firstly, it’s essential to know that the surface area and weight of a die solid 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 feature computerised real-time shot control, computerized ladling, die-spray, computerized casting extraction and cooling - providing repeatability and productivity.
In addition, other foundries may only supply their providers for high quantity orders, claiming that prolonged set-ups make the process prohibitive to small runs.
