摘要: The mould comprises a base plate and a plurality of forming areas, wherein each forming area comprises a cavity in the base plate and a forming sleeve placed in the cavity. Each forming area further comprises first heat means for heating or keeping heated the forming sleeve relative to the base plate, such that the temperature of the part of the film which lies against the forming sleeve during cooling remains above a glass temperature of the plastic long enough to obtain a product with an at least partially crystalline structure.
