LiSEC has reduced remnant glass plates and broken sheets through software optimisation at Gethke Glas Gronau in Gronau, Germany.

The glass manufacturer has installed the LiSEC Dynopt, an optimisation tool for cutting, in order to save time and material.

Lothar Schleiner, Authorized Signatory and Plant Manager at Gethke Glas Gronau said: “Between 100 to 130 optimised files are always displayed on the Dynopt screen of the ESL float cutting table.

“With the button ‘Same glass code’, we keep the overview and see how many files of the individual types of glass are in the Dynopt pool, not limited to delivery dates.”

Since the implementation of Dynopt, employees in Planning and Scheduling no longer pay attention to remnants or disassemble them, but pass on everything 1:1 to dynamic optimisation, so that the optimisation task is entirely taken over by LiSEC Dynopt.

Mr Schleiner said: “There are hardly any remnant plates left in the company.

“Since we have been using Dynopt, time savings are about three hours a day, that is one hour per shift.

“All in all, we have reduced waste by approximately 3% since we have been using the LiSEC software tool.”

When Gethke Glas had broken, heavily soiled or scratched glass sheets in the past, the staff wrote a remake note with detailed information on the respective glass sheet. This included dimension, type of glass and production line, and was sent for manual glass cutting.

Mr Schleiner explained: “We appreciate the fact that LiSEC does not only build machinery, but is also an insulating glass producer itself and thus has a completely different understanding of the needs of customers.

“In addition, the company also has the opportunity to test its software and machinery beforehand.

“What we also like very much is the telephone availability of the service department, especially LiSEC Software.”

Thanks to GPS-Ident or Remake Pool, where all remakes are collected and processed, combined with Dynopt, the original process has become completely redundant.

Now defective sheets are scanned, immediately sent to the Remake Pool and then processed as fast as possible in Dynopt. With the extension ‘Re-Opt’ on the cutting table, Dynopt optimises a glass sheet once the cutting process has already been started or remakes are inserted. This means a sheet subject to a complaint can be returned to production in no time.
