An aluminum food container manufacturer was using IPA mixed with oil for
stamping aluminum food containers. They were facing multiple issues related to
smell, cracking around critical bends and safety of consumers due to incidental
contact of the lubricant. They requested Molygraph for help in finding solutions.
Molygraph suggested Punch 4300S SRI for this application. Punch 4300S SRI
has been approved by the FDA for incidental food contact. It is also highly
lubricious and evaporates quickly after the stamping process is over, leaving a
clean surface. The other critical part of the operation was the accurate forming
of the bends in the container. No cracks were observed while using Punch 4300
S SRI and the operation went along smoothly.
The lubricant application was changed to a spray system for optimised lubrication.
This further improved rate of evaporation and substantially decreased lubricant
The goals and objectives of the customer had been met. Molygraph’s focus
on productivity and performance has once again given tangible benefits to the
