3. It should be able to sustain brand-new development. We have won 14 brand-new contracts in the last 4 months, and new manufacturing is beginning within a year. 4. Information is everything. We require to be able to narrow it to the change at a minimum. Preferably the time, operator, equipment, component #, batch #, amount.


The same system has actually to be made use of for all stages of manufacturing: Casting, Trimming, Shot Blasting, Machining, et all.
