About us

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.

16 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.
