In injection moulding, a raw mixture is prepared according to an individual formula and injected into a cavity (the mould), where it is vulcanised under the influence of pressure and temperature. This method is particularly suited to the production of articles with more complex geometries that impose stricter tolerance requirements on the finished moulding. Depending on the complexity of the article and the desired production run, it is possible to apply various production concepts using either conventional or specially designed moulds.
The stamping process shapes a material with the help of a pressing die in a similar manner to injection moulding. Unlike in injection moulding, however, the raw mixture is divided into portions and inserted by hand.
