description The core material of the invention is composed of wax, bee wax, turpentine oil, copper powder, graphite powder, etc. The materials of wax, bee wax, turpentine oil in predetermined proportion are first heated and dissolved in a mixing container and then graphite powder, copper powder, turpentine oil are added and stirred into a thick paste; the paste is poured into a core mould and a copper conductor is inserted into the central part without any contact with the mould wall, then electroforming, core material pouring, moulding and reelectroforming. The product of this invention has vivid image, smooth appearance, sturdy and durable structure but requires less cost than that by mechanical means. This is a technique that can not be accomplished by mechanical or manual work.
