Summary:Methods and apparatus for demolding lens mold assemblies are described in which the lens mold assemblies are positioned below punchers (50) each with at least one punch pin (104). The punchers are then moved against the lens mold assemblies (10) so that the at least one punch pin of each puncher punches through a lens mold layer of a first mold part to then push against a second lens mold layer of a second mold part to separate the two parts in a demolding process.
