A New Way to Improve Thermal Capacities of Lubricants for the Manufacture of Flint Glass Perfume Bottles: Part B—Thermal Analysis and Physico-Chemical Observations for the Different Lubrications at the Glass/Punch Interface


In the hollow glass industry, more specifically in the luxury perfume glass bottle industry, the success of the forming process depends on controlling the thermal exchange at the glass/mold interface to prevent defects on the glass surface. This study concerns a new way to analyze the impact of lubrication on the glass/tool thermal exchanges. It combines the thermal analysis on the experimental Glass/Tool Interaction (GTI) platform in the TEMPO Laboratory (Valenciennes, France) and the Physico-Chemical measurements on the glass samples by the BCR Center (Mons, Belgium). Part B presents the analysis of the flint glass pressing cycles using different punch lubrication conditions (i.e., bare punch, swabbed punch, coated punch, and coated/swabbed punch). The thermal analysis permits us to rank the lubrication conditions in terms of their capacity to limit the thermal exchange at the punch/glass interface. We defined a new lu- bricating paste composition based on the Physico-Chemical observations of the lubrication transfer on the pressed glass. The GTI platform results proves that the new composition does not affect the insulating power of the lubricating paste and permits us to eliminate defects on the glass samples that are not accepted in industrial situations.
