CUSTOM CASTING We offer a custom casting service in white metal and resin. Please call for prices and lead times. Masters for moulding are best made in metal (brass), and milliput but a more expensive mould can be made if masters are made in plastic, wood etc. Mould costs start from £25 but this can be reduced if you are able to wait until several items can be placed together and the cost divided between the owners of the masters. Unit cost from the moulds can only be given when size, weight and number required is known.
