A mould is made of a synthetic resin material e.g. an epoxy or polyester resin containing a particulate filling agent of a magnetizable thermally conductive material e.g. an iron powder (so as to cause the particles to form substantially continuous chains. The hardening of the resin is effected in a magnetic field). The mould is located in an open-topped container of non-magnetic material.
