These projects represent a significant uplift in demand for GW COSCAST and will lead to further investment and a doubling of the workforce. GW is seeking to add a further 20+ jobs including supervisory, technical and operative roles.

“We are delighted to be identified by Cox Powertrain as the ideal partner for it’s incredible new diesel engine project,” says Matthew Grainger, GW director. “The innovative casting technologies employed by our company make us the ideal supplier for Cox Powertrain’s ambitious programme, which requires its first engine casting deliveries to be made by year end. Our agile, flexible approach is the perfect solution for manufacturers and suppliers working to short timescales who require reduced lead-times without jeopardising quality control.”

The company is one of the famous, original Cosworth foundry facilities in Worcester, blazing a trail in casting process technology. Grainger & Worrall Limited (GW), the Global Leader in high-performance castings, bought the company from Mahle Group in 2016, securing the future for the business and it’s 26 employees.

GW COSCAST is recruiting for Engineer, Technician and Operative roles at our Worcester Facility.
