The Service
I can offer a mould making service to sculptors and individuals who wish to produce copies of their work. Moulds can be used to cast plaster replicas of the original piece or to create wax patterns that can be used in the lost wax process for producing a bronze. I can make simple one piece moulds or more complex multi-part moulds. I generally use silicon rubber or latex to capture the detail of the piece and use a plaster mother mould for support. If the sculpture is large then a stronger fibre glass mother mould is used instead. The cost of this service is dependent on the size and the complexity of the sculpture used. Larger more complex pieces will either require the the mould to be made of a number of parts that fit together like a 3 dimensional jigsaw or for separate moulds to be made for different sections of the sculpture. For example limbs and items that are distinct, very long or distant from the main body of the sculpture many need to be moulded separately. If you are interested in this service please send me an email through the 'Contact Us' page in the first instance briefly describing the piece, its size and what you will be casting into the mould when it is complete. Please include your contact details and preferred method of communication and I will get back to you with a price.

Mould Making Process |
||
|
A mould is usually constructed of two layers or the outer and inner mould. The rigid outer mould contain the softer inner mould, which is the exact negative of the original model. The inner mould are usually made of latex, polyurethane rubber or silicone, which is supported by the outer mould. The outer mould can be made from plaster, but can also be made of fiberglass or other materials. Most moulds are at least two pieces, and a shim with keys is placed between the pieces during construction so that the mould can be put back together accurately. In case there are long, thin pieces sticking out of the model, these are often cut off of the original and moulded separately. Sometimes many moulds are needed to recreate the original model, especially large ones. The process below describes the constroction of a two piece silicon rubber inner mould supported by a 4 piece plaster mother mould • Building A Wall . • First Silicon Rubber Inner Mould. • Upper Mother Mould. • Removal of Wall and Cleaning. • Second Part of Inner Silicon Mould . • Lower Sections of Mother Mould . • Removal of Original . • Pouring the Wax. • Removal of Wax Copy. |
