3. It needs to be able to support new development. We have won 14 new contracts in the last 4 months, and brand-new production is beginning within a year. 4. Detail is whatever. We require to be able to tighten it down to the shift at a minimum. Ideally the moment, operator, equipment, part #, batch #, quantity.


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