A method of moulding an element of an insulating material, such as a thermosetting plastics material, on a bimetal strip in which the bimetal strip is clamped in an injection mould by narrow clamping jaws disposed on either side of the mould cavity in the longitudinal direction of the bimetal strip. The width of the clamping jaws is such as to enable the remaining portions of bimetal strip to bow freely in response to heat present in the injection mould. |
