Quality & SPC Expertise

Statistical Process Controls (SPC)

We believe controlling process inputs yields controlled coating outputs. We have developed and use the most advanced process controls in metal finishing. There are approximately (90) parameters that are measured, controlled, and documented throughout our processes including; chemical mixing, chemical processing, coating qualities, and heat treatment. The frequency of measurement for each parameter is sufficient to guarantee adequate control.

Where practical our processes are automated. Control of the chemistry from which coatings are deposited is the most critical. Measurements are made frequently and chemistry replenishment is made continuously through automated equipment. A visual system prevents chemistry from going out of control, but if it does it also prevents customer components from entering a process that is not in control.

This system allows us to make coatings that rigidly conform to quality requirements.

Some further insight into our quality control:

  • Our facility is ISO 9001:2008 certified and is dedicated to the notion of continuous improvement.  The ISO system was brought in house as a management choice, not by customer requirement.  In other words, UCT chose to use have world-class quality and is dedicated to it through the ISO process.  Our customers often say we have “industry leading” process control.
  • We work to customer specifications, not specifications imposed by us. For instance, when appropriate we ask that customers create engineering drawings dictating coating type, thickness, surface finish, hardness, and any other parameters required as well as the preferred inspection method.
  • A complete written material specification for our proprietary coatings exists and can be used to specify our coatings, and is frequently used to facilitate the generation of OEM internal specifications.  If we are supplying an industry standard coating it can be supplied per the appropriate standard.
  • If certification of conformance is required we can provide that once an agreement is made on what is to be certified and how.
