Abstract
A method of manufacturing, at least in part, a composite mould tool is described. At S101, 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 S102, 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 S103, the method comprises providing a faceplate of the composite mould tool by subtractive manufacturing of the first face.

A method of manufacturing a composite mould tool, the method comprising:
- obtaining a mould tool precursor having a first face and a reverse second face, wherein the precursor comprises and/or is a first metal, wherein the precursor comprises a perforation extending between the first face and the second face (S101);
- hermetically sealing the precursor by cold spraying a layer on the second face using particles comprising and/or of a second metal, wherein the respective coefficients of thermal expansion of the first metal and the second metal are within a factor of 5, wherein the layer does not have any perforations therethrough and wherein the precursor is the mould tool before the layer is cold sprayed on the second face (S102);
- and
- providing a faceplate of the composite mould tool by subtractive manufacturing of the first face (S103);
- thereby manufacturing the mould tool having the faceplate provided by subtractive manufacturing of the first face and the reverse second face hermetically sealed by cold spraying the layer thereon.
