Should I Use Polyurethane Mold Rubber or Silicone Mold Rubber?
Among the most commonly used mold materials are liquid latex, silicone rummer, urethane rubber, and alginates. Common cast making materials include Plaster-of-Paris and Gypsum cement, concrete, plastics resins and epoxies , waxes, metals. Most mold making materials are utilized are made from natural or manmade rubber because of their flexibility and the ability to reproduce extraordinary detail. But some molds are made with more rigid materials such as gypsum plasters.
On completion of a clay model there may be a requirement to make a more permanent reproduction or series of reproductions and the techniques involved are mould making and casting. A mould is a negative impression of the original sculpture and can be made in one of many materials for example; plaster, liquid latex, silicone rubber or vinyl rubber and can be as simple as a one piece block or a complex multi-piece mould made of many connecting parts. The choice of moulding material is determined by many factors, the material the original is sculpted in, the quantity or material the reproductions are to be cast in and the size or level of detail of the sculpture. Latex is air drying and most commonly used for casting plasters and cements, it is applied in layers to build up a desired thickness before receiving support in the form of plaster or fibreglass. Vinyl rubber is a re-useable rubber which is heated to a liquid and poured over the sculpture where it cools back to its original flexible state, vinyl is a good material for small numbers of castings but unlike other mould making materials can be re-melted and formed into a new mould.
