3. It has to have the ability to sustain brand-new development. We have actually won 14 brand-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 narrow it to the shift at a minimum. Ideally the moment, operator, equipment, component #, set #, amount.


The very same system has actually to be made use of for all phases of production: Spreading, Trimming, Shot Blasting, Machining, et all.
