Tooling
We develop and maintain the die together with your design team. A DFM review before the tool is ordered saves both time and money later on.

We make complete aluminium manufacturing simple to buy
Proal is a complete system supplier in aluminium high-pressure die casting. We control the entire chain — from tooling to a surface-treated, assembled and delivered product — in two plants of our own in Sweden and Poland.
Die casting
Six robot-tended casting cells, 320–1,850 tonnes.
CNC machining
Eleven machining centres and lathes with driven tools.
Surface treatment
Chromating and powder coating on our own line.
Assembly
Sub-systems, marking and customer-specific packaging.
Machine park
The full machine park, machine by machine.

Plants
Two plants, one responsibility
Sölvesborg casts and machines. Wejherowo does surface treatment and assembly. You get one contact and one article number regardless of where the work happens.

The value chain
Six steps, one responsibility
Follow a part through our process — from tool design to a product ready to ship.
Die casting
Six robot-tended casting cells with clamping forces from 320 to 1,850 tonnes. Part weights from 5 grams to around 25 kilos, in recycled aluminium alloy.
Machining
Vertical and horizontal machining centres with up to 40 tool stations, plus multi-tasking lathes with driven tools for complete machining in few set-ups.
Surface treatment
Blasting, tumbling, ball polishing, vibratory deburring and a complete chromating line with subsequent powder coating, all in-house.
Assembly
Manual finishing, pad printing, balancing of parts with high rotational speed requirements, sub-assembly and packaging to your specification.
Delivery
Inspection reports, traceability and call-offs to an agreed plan. Delivery from Sölvesborg or Wejherowo — or straight to your final assembly line.
Capabilities
Four disciplines under one roof
Each one strong enough to stand alone. Together they are what we actually sell.
Capability 01
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.

Capability 02
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.

Capability 03
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.

Capability 04
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.

Industries
Where our parts end up
We supply customers with high demands on documentation, repeatability and delivery precision — across five segments.
Medical technology
Enclosures, chassis and load-bearing structures for medical equipment, where the documentation matters as much as the part.

Through recycling to a new product
Our products are cast in recycled aluminium alloy. Besides protecting the environment, it also makes for a better end product. Our energy is mainly hydroelectric.
We work to a management system certified to ISO 9001 and ISO 14001, and invest continuously in machines with a lower environmental impact.

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.
