Abstract

An apparatus for shaping a workpiece made of glass using minimum lubrication is provided. The apparatus includes device for heating the workpiece, a shaping station with at least one forming tool for shaping the workpiece, and at least one spray nozzle for applying an oil as a lubricant onto the surface of the forming tool. The forming tool exhibits heat dissipation such that the temperature on the contact surface of the forming tool during the shaping process is kept below 300° C. The amount of oil dispensed by the spray nozzle per forming step and application instance is less than 0.1 g.
