Plastics Quality & Regulatory


We utilize the APQP process in early development for new programs. All parts are measured as part of an FAI. For those customers requiring more validation and statistical information, we can offer IQ/OQ/PQ or PPAP, depending upon industry and regulatory requirements.

Metrology Services


At the onset of a project, Quality and Engineering work closely with customers to arrive at best methods to conduct GD&T. Our metrologists use multiple inspection methods including CMM that have both visual and touch probe capabilities as well as other pieces of equipment such as Optical Comparators, gages and fixtures.
