3. It has to have the ability to sustain new growth. We have actually won 14 brand-new agreements in the last 4 months, and brand-new manufacturing is starting within a year. 4. Information is whatever. We need to be able to narrow it down here to the shift at a minimum. Ideally the time, driver, machine, component #, batch #, amount.


The same system needs to be made use of for all phases of manufacturing: Spreading, Trimming, Shot Blasting, Machining, et all.
