Summary:Methods, devices, and systems for demolding lens mold assemblies are described in which the lens mold assemblies are positioned below a puncher header each with at least one punch pin. The puncher header is then moved against the lens mold assemblies 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.
