We have actually won 14 brand-new contracts in the last 4 months, and brand-new manufacturing is beginning within a year. We need to be able to narrow it down to the shift at a minimum. Preferably the time, operator, machine, part #, batch #, amount.


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