Doncasters Precision Castings – Deritend, is a leading manufacturer of investment cast and machined industrial gas turbine airfoils. These airfoils are manufactured in nickel and cobalt based superalloys. The company is committed to growth and it backs this commitment with a willingness to invest in continuous improvement through lean manufacturing and rapid prototyping. As a result, it has seen considerable growth in demand for its machining services, which support its investment casting business. This demand has led to a significant investment of over £2 million in Mazak machine tools, infrastructure and manufacturing software to efficiently machine over 14 new products.
