Abstract

603,072. Moulding wax articles. TURNBULL, J. S., and METROPOLITANVICKERS ELECTRICAL CO. Ltd. March 5, 1946, No. 6831. [Class 87(ii)] Molten wax is injected under pressure into a closed mould, and when the external layer of wax has solidified sufficiently for inward collapsing to occur an electric heating wire located substantially centrally of the wax is temporarily energized and air is forced into the wax in the neighbourhood of the wire. A pressure compartment is thus formed within the wax, whereby the outer layers are held against the mould wall. After the wax is substantially solidified, the heating wire is again energized to soften the adjacent wax sufficiently to release the trapped compressed air. The wire may be removed or left in the wax. The Figure shows apparatus for carrying out the process, comprising a two-part mould 1, 2, a wire 4 connected to a terminal block 5, feed pipe 7 and injection nozzle 8. A similar feed pipe and nozzle are used to inject compressed air.
