Abstract
A method of manufacturing, at least in part, a composite mould tool is described. At S, the method comprises obtaining a mould tool precursor having a first face and a reverse second face, wherein the precursor comprises a first metal. At S, the method comprises hermetically scaling the precursor by cold spraying a layer on the second face using particles comprising a second metal, wherein the respective coefficients of thermal expansion of the first metal and the second metal are within a factor of 5. At S, the method comprises providing a faceplate of the composite mould tool by subtractive manufacturing of the first face.
