Our great deal tracing methods seem very primitive, a literal tag (published sheet of paper) that literally adheres to the components.


We have actually won 14 brand-new contracts in the last 4 months, and brand-new manufacturing is starting within a year. We require to be able to narrow it down to the shift at a minimum. Ideally the time, operator, machine, component #, set #, quantity.


The very same system has actually to be utilized for all stages of production: Casting, Trimming, Shot Blasting, Machining, et all.
