Abstract
It is presented a method for producing a cured polymer structure from a polymer compound which is UV curable and partly UV transparent. The method comprises injecting the polymer compound into a mold (2), which mold (2) has at least one wall (7) defining a mold space (6) for receiving the polymer compound in the mold space (6). The at least one wall (7) of the mold (2) is UV transparent and comprises a thermoplastic polymer. The polymer compound is then irradiated through the at least one wall (7), by means of at least one UV semiconductor light source, thereby curing the polymer compound to form the cured polymer structure. An assembly for producing a polymer structure and a mold (2) is also presented herein.

A method for producing a cured polymer structure from a polymer compound, which polymer compound is UV curable and partly UV transparent, wherein the method comprises:
- injecting (S1) the polymer compound into a mould (2;
- 2′), which mould (2;
- 2′) has at least one wall (7) defining a mould space (6) for receiving the polymer compound in the mould space (6), wherein the at least one wall (7) is UV transparent and comprises a thermoplastic polymer and wherein the at least one wall (7) is so thin that the at least one wall (7) is flexible, and wherein the mould (2, 2′) is a blister pack, and
- irradiating (S2) the polymer compound, through the at least one wall (7), by means of UV light provided by at least one UV semiconductor light source, wherein the irradiating comprises irradiating the at least one wall (7) such that UV light passes through the polymer compound, thereby curing the polymer compound to form the cured polymer structure.
