To Deliver the Maximum Stakeholder Value, by Being… the “Global Supplier of Choice” for Cast Aluminium and Machined Automotive Components

CastAlum is an internationally acclaimed aluminium diecaster, located in Mid Wales. The site was a Greenfield development in the winter of 2000-2001, serving one customer only.

18 years on, the company supplies parts to the UK, Germany, Poland, Canada and Mexico and recently won its first order from a truck manufacturer in the Far-East. 80% of all production is for export, with our components going into vehicles produced by Jaguar, Aston Martin, BMW, Ford, General Motors, Fiat, Renault, Porsche and Mercedes.

Over the past 5 years the Company has invested heavily in the development of new products. Through our own investigation and expertise we have been able to bring a number of process solutions to bear in meeting world class quality standards. 

Today, one in ten vehicles produced in Europe has a steering gear housing manufactured by CastAlum in Welshpool.
