Northumberland-based Vald. Birn (UK), a subsidiary of the Danish Birn foundry group, is close to completing a £5m expansion programme. A second George Fischer DISA Combi-Core unit has now been commissioned, with facilities for a third machine to be installed at the same time. Foundations have also been laid for a fourth Disamatic moulding machine, which will be commissioned by the end of the year. A new melting plant is due next year, on top of work already started to build extensions to the existing foundry for a new 1,800sq m finishing hall and a 900sq m Shotblast hall.
