Mould Production Part 2


Production moulds.

Production moulds are the final step to mass production of metal miniatures. If you are going to want more than moderate numbers of your cast sculpts then a Production-mould will be necessary. Production moulds are made from industrial grade organic rubber which needs to be vulcanised, this is the process of adding heat and pressure to harden the rubber to its finished state. Master-castings need to be used to resist these stresses. Production moulds can be either of 228mm (9") or 280mm (11"), a full 228mm production mould can contain about 16 x 28mm scale minis. 280mm moulds may be needed for large items or for larger than normal production runs. Production moulds are run to destruction, as many as possible usable minis are taken from each mould and when exhausted the mould is cut-up and discarded. Moulds with normal level of undercutting will last over 160 spins giving large quantity's of usable castings for sale.
