  • Method of making a moulded article
    Patent number: 4854366
    Abstract: In the production of moulds for making moulded articles, e.g. foundry moulds for producing castings, it is known to consolidate resin-coated granular filler in a moulding box containing a pattern to form the mould pieces. A gas such as SO.sub.2 is passed through the filler to cause it to set. However, after repeated use, resin buildings up on the pattern plate. According to the invention, the pattern is provided with a layer of silicone release agent such as siloxane which prevents resin build-up yet can be easily washed away.
