A meshed shell and a sandblasting method are provided. The meshed shell includes a first end portion, a second end portion opposite to the first end portion, a first annular portion, a second annular portion connected to the first annular portion, a first mesh portion between the first end portion and the first annular portion and a second mesh portion between the second end portion and the second annular portion. The weights of the first end portion and the second end portion are the same. A maximum inner diameter of the mesh of the first and second mesh portions is smaller than a penetration size of the component. Both of the sum of the weights of the first and second end portions and the sum of the weights of the first and second annular portions are greater than the sum of the weights of the first and second mesh portions.

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.
