In addition to its basic documentation and procedural structure, we have a deep focus on process control and the use of statistics with our manufacturing processes. This process control focus is central to our launching of new product lines and manufacturing processes, as it is with all our APQP processes. Our incoming, in-process, final inspections, and process capability studies are done with the latest vision systems and test equipment all traceable to NIST and independently audited. It is the combination of our engineering and tooling expertise, use of statistical evaluation tools, production staff discipline, high quality inspection/test equipment, and the continuous improvement feedback loop that adds up to REAL process control and capable product development. We are a manufacturer—strict and meaningful control of our manufacturing processes is who we are and what we do.
