We have won 14 new agreements in the last 4 months, and new production is starting within a year. We need to be able to narrow it down to the change at a minimum. Preferably the time, operator, device, component #, set #, quantity.


The same system has actually to be utilized for all phases of manufacturing: Spreading, Trimming, Shot Blasting, Machining, et all.
