  • Method of preparation of sand casting moulds with a protective coating
    Patent number: 11179768
    Abstract: A method of making sand casting moulds with a protective coating for a multiple process of reactive moulding of insulation components and products made by filling up a mould cavity with polymer materials, including composites, based particularly on epoxy resins or composites based on cellulose materials, the method wherein the process of infiltration of the mould structure is performed chemically by soaking through the raw mould structure with chemosetting or thermosetting material. The application of a protective layer on external surfaces of a sand casting mould is done by means of any spraying, immersion or deposition method, whereas material with anti-adhesive properties is used for the protective coating in the form of organic chemosetting, thermosetting, light-curing material or in the form of inorganic material, including metal.
