Beschreibung
Zusammenfassung:	The invention is directed to a method and an apparatus for the production of three-dimensionally thin products using injection moulding of polymer based material. By dividing one of the mould halves in at least two groups of elements, whereby at least a first group of at least one element forms a rim cavity and a stop, defined as an area of the element contacting the other halve if the mould is in the closed position, and at least a second group of at least one element forms the main body part of the cavity, whereby all the elements together form with the other mould halve one cavity, and whereby each of the groups of elements is connected to its own means for clamping, it is possible to produce a set of different products with a constant rim thickness and a variable thicknes of the main body part of the product.
