We have won 14 brand-new agreements in the last 4 months, and new production is starting within a year. We require to be able to narrow it down to the shift at a minimum. Preferably the time, operator, machine, part #, set #, quantity.

The same system needs to be used for all stages of production: Spreading, Trimming, Shot Blasting, Machining, et all.
