High Pressure
Die Casting
Automated, industry leading excellence
CastAlum has been high pressure die casting in the heart of Wales for over twenty years, so it’s fair to say we know a lot about the process!
About High Pressure Die Casting
A history of HPDC
While high pressure die casting (HPDC) has been around for several decades now, in its infancy it was considered an inferior process to its main competitor: gravity die casting. Some of the original problems with HPDC were:
- Expensive to set up
- More suited to long runs and large quantities
- Higher porosity and generally lower quality
For several years parts produced by the HPDC process were understood to be cheaper, but of inferior quality. To further emphasis this, HPDC utilized the LM24, considered a low-level material in terms of both quality and price.
Refining the die casting process
As die casting machine manufacturers such as Buhler Prince made their equipment more robust and predictable, the level of performance and quality of the parts began to improve. These advances included:
- Control mechanisms on shot speed, clamping, etc.
- The ability of a machine to automatically shut down a process
- Quality control from parts per minute to zero defect and then to single part rejection
The necessity to produce parts right first time has resulted in an industry-leading production process. Through the constant refinement of an already mature method, CastAlum has achieved levels of excellence that would have scarcely been thought possible back when the company was founded at the turn of the century.
The future of HPDC
Even with all these recent improvements, technical progress continues to be made. Nowhere is this more apparent than in our provision of parts to the expanding electric vehicle (EV) market. As a visionary within the industry, CastAlum is always striving to find new levels of performance and engineering distinction through a range of possibilities converted into successes, including:
- Innovation in engineering design and enhancements to in-process controls
- Light weighting whilst providing yet more complex geometries with improved integrity and strength.
- Unparalleled tooling durability with innovative additive manufacturing
Armed with over twenty years of experience and ever-increasing skillset, we’re looking forward to providing the continuous improvement and competitive benefits of high pressure die casting to our customers for the next twenty years too!

Our Die Casting Process
Metal
We can support a variety of aluminium, depending on the scope and requirements of individual projects.
Furnace
All machines have their own tower melting furnaces, ensuring a better management and quality of molten metal.
Ladle
Our process is completely automated, with automated robots handling the delivery of metal to the cavity.
Control
We are able to perform part segregation through our specialised machine process control software ‘Pro-Link’
Spray
The die faces are cleared and cleaned of any debris before each shot, thus ensuring a consistent surface.
Extraction
Parts are carefully extracted, ready for secondary process before being delivered to the operator.
Tooling
Development of Additive Material Inserts providing industry-leading cooling flow during solidification
Quench
Parts are cooled before being trimmed, to ensure the safety of our operators when handling any parts
Trim
All runners/risers are trimmed and recycled at the cell, with our robots capable of secondary processing
Quality
Parts are checked and processed by our skilled operatives, with onsite x-ray checks as required throughout shifts.
Packed
We are able to accomodate a wide range of packaging needs, depending on the requirements of the part.
Shipping
We have decades of logistical experience as a high-volume supplier distributing in Europe and worldwide.
