Abstract

A peg of conducting material is placed in the mould wall so that it projects into the interior of the mould cavity and is heated to a temperature such that the resin melts around it so as to form a sheath during rotational moulding. The invention overcomes the precious difficulty of incorporating attachments such as clamps, screws etc. in mouldings formed by rotation.
