Abstract: The invention relates to a method for forming an article by injection molding, such as a shoe, and comprises the formation of a mold (5) by coating a master pattern of the article with a pourable, heat-resistant molding compound, such as an epoxy resin or polyurethane. The master mold (5) so formed is secured in a mold casing (1) for an injection molding plant and molding material such as poly-vinyl chloride or polyurethane is injected to form the finished article. The master mold may be formed directly in the mold casing (1) to which it can be secured such as by mechanical securing and located means (6,7,8,) or by being adhered thereto. In an alternative embodiment of the invention, the master mold may be formed in a mold box and subsequently fitted into the mold casing (1) for reproduction of the article.
