PRODUCTION METHOD FOR A HEADLIGHT LENS AND HEADLIGHT LENS FOR A MOTOR VEHICLE HEADLIGHT

摘要

The present disclosure is directed to a method for manufacturing a batch of motor vehicle headlight lenses, each lens comprising a lens body and a convexly curved optically operative surface. The method comprising pressing a pre-form between a first mould and a second mould, which second mould comprises a first and second mould sections. An offset depending on the volume of the pre-form a step is pressed into the headlight lens between the second mould section and the first mould section, wherein the first mould section is set back with respect to the second mould section at least in the region of the offset, and wherein the height of a step of a headlight lens of the batch differs by more than 0.05 mm from the height of a step of at least one further headlight lens of the batch.
