Definitions

  • the present invention relates to a method of producing a mould.
  • the present invention is particularly, although not exclusively, -concerned with a method for production of multiple identical moulds suitable for moulding products from composite materials.
  • mould can apply to the situation in which the mould produced is a mould half to be used in conjunction with a corresponding opposite gender mould half in a closed face arrangement, or where the
  • mould is the entirety of the moulding apparatus in an open face arrangement.
  • moulds suitable for moulding products from composite materials from a mould former, which is sometimes known as a plug.
  • resin can be hand-shaped or computer-cut to form a mould former with a shape
  • wet lay-up in which uncured material (which may itself be a composite material) is applied to the mould former by hand and allowed to set.
  • a method of producing a mould for a product comprising the steps of providing a sheet of material having first and second faces, and forming the sheet onto an open face primary mould former having a shape corresponding to a required shape for the mould with the first face of
  • the second face of the sheet is therefore the face which will subsequently receive and
  • the first face of the sheet is the face which is not subsequently in contact with the material to be moulded in use of the mould.
  • the face of the sheet material which is remote from the mould former when the sheet is formed into a mould is therefore the face for receiving material to be moulded into a product.
  • the method is possible because the material used to produce the mould is in sheet form.
  • the mould of the present invention is itself formed by moulding, and the product is subsequently moulded using the mould.
  • the sheet material is preferably thermoformable.
  • thermoforming techniques the amount of time taken to apply the mould material onto the mould former and the amount of time for which the mould former is occupied can be greatly reduced.
  • the mould material may comprise a thermoformable plastics material, for example acrylonitrate-butadiene-styrene (ABS). ABS is a suitable material to use for producing moulds because it is very tough.
  • ABS acrylonitrate-butadiene-styrene
  • the sheet material may comprise acrylic-capped ABS. This is a sheet of ABS with a thin film of acrylic bonded to one face.
  • the acrylic film is preferably on the second face of the material because it maintains an excellent surface finish after moulding and is therefore suited to receive material subsequent product for moulding.
  • Other films, such as polyester or styrene film may also be used.
  • the choice of film may be dependent upon the material which will subsequently be in contact with the second face in moulding operations.
  • the film must be compatible and preferably non-reactive with the product material, particularly if the product is to be removed from the mould after curing.
  • the plastics material preferably will have properties such as impact resistance, stiffness, resistance to shrinkage following moulding and temperature resistance to allow curing cycles in the mould if required.
  • the mould former must be suitably shaped in order to accommodate the difference in size of the mould compared to the mould former due to the thickness of the sheet.
  • the method of the present invention may further comprise the step of coating one or both of the first and second faces of the mould.
  • the second face of the mould may be treated with a metallic surface finish, such as chrome-plating. Whilst the shape of the mould is dictated by the face of the sheet, a thin metallic surface finish can act to protect the sheet surface from the material to be moulded, allows the article produced in the mould to be removed easily following moulding, and acts as a skin to make the surface non-porous.
  • the mould Once the mould is formed it may be ready immediately for use in moulding operations. If the sheet material is relatively thin then it may be too flexible- after formation to function as a stand-alone moulding unit not requiring any support to maintain shape. Accordingly some form of backing structure may be required.
  • the sheet may still be flexible, even, for example,
  • a coating may be applied to the sheet to stabilise the shape of the mould.
  • the stabilising coating may be a foamed compound, for example Froth-Pak (registered trade mark) which is produced by Eco Polyurethane Systems.
  • the foamed compound may be fire-retardant and/or solvent free, which would be advantageous particularly from a health and safety perspective.
  • a stabilising coating may be applied to the first face of the sheet, which is the face of the mould formed in contact with the mould former.
  • the method may therefore further comprise the step of laying the sheet onto a secondary mould former which is_ oppositely shaped to the primary mould former, such that the first face is exposed thereby allowing it to be coated whilst supported in its required shape.

  • An open face mould produced according to the present invention can then itself be used as a mould for subsequent forming of components.
