 Quality Control

Managing quality by the ultimate standard

By any modern statistical measure, SmartPrototype meets or exceeds the quality standards of the world's most demanding industries.

  • Compliance with FDA and FAA requirements, including DFARS materials sourcing requirements
  • Strict compliance with PPAP and Process FMEA for automotive customers
  • Skilled in KanBan and other customer driven quality and inventory management systems

Meeting these requirements focuses our working environment on process control metrics.  SmartPrototype  customers benefit from the X-bar and R charting, histograms, capabilities studies and CPK analyses that are a daily reality on the Cox shop floor.

Amidst this wealth of data, one number stands out as essential in defining  SmartPrototype quality. The number is 1956, the year of our founding. Cox was created in an era when quality wasn’t just a statistic, but a relationship of personal trust that meant you could count on a company to deliver on its promises. By sustaining this tradition of pride alongside a commitment to process control, we’ve found what we believe to be the most reliable and reassuring standard of quality by any measure.
