Industry 05
Energy
Cooling housings and structural components for power electronics and energy-related products — a segment growing fast with us.
The challenge
Power electronics keep getting denser and hotter. Cooling has to be built into the casting itself, while the housing must stay tight, be sound from an EMC perspective, and remain manufacturable at volume for a sensible cost.
What we do
Die casting is the right method when fin geometry, cooling channels and mounting points all belong in the same part. We design for castability together with you, then machine the faces that need flat, tight interfaces.
Requirements we meet
- Thin, dense fins with high thermal performance
- Flat sealing faces for gaskets and EMC strips
- Dimensional accuracy on mounts and interfaces
- Volume capacity as the programmes scale up
- Recycled alloy with a low climate footprint
Typical parts
- Finned electronics housings
- Inverter enclosures
- Load-bearing frames
- Connection details

Die casting
The foundry machine park allows us to produce parts from 5 grams up to around 25 kilos. Clamping forces range from 320 to 1,850 tonnes. All casting cells are robot-tended, which secures high productivity, flexibility and quality.
CNC machining
Our machining department runs both vertical and horizontal machining centres with up to 40 tool stations each. For efficient, high-quality precision work we also have multi-tasking lathes with driven tools.
Surface treatment
Proal has broad knowledge of surface treatment methods for die-cast aluminium: blasting, tumbling, ball polishing and complete chromating with subsequent powder coating. Together with you we find the solution that best fits the need.
Assembly
We deliver finished products, not semi-finished parts. Manual finishing, pad printing, balancing of parts with high rotational speed requirements, sub-assembly and packaging — all to your specification.

Got a drawing?
Send it over. You will get a technical assessment and an indicative price from someone who will actually make the part — not from a sales organisation.
We accept STEP, IGES, 3D models and 2D drawings. Confidentiality goes without saying.
