Quality Control and Inspection

TTH and SAS are committed to ensuring all parts and prototypes we deliver to our customers meet the stringent requirements of the aerospace and medical industries. To meet these high standards, we employ a variety of inspection tools and quality management processes:

  • An optical comparator allows us to magnify a part and display it on screen for visually comparing its dimensions and geometry with the specified limits.
  • A Zeiss Contoura G2 Coordinate Measuring Machine (CMM) allows us to measure a wide variety of components with accuracy of 0.00008-in over 3 inches. It’s ideal for measuring precision-machined components and tooling to tight tolerances with high repeatability. A flexible articulating probe allows scanning in all angular positions. With a measuring range of X = 700 mm, Y = 1000 mm, and Z = 600 mm, this CMM allows us to perform highly automated inspections that are less dependent on human operation. Its high sensitivity allows detecting process changes at an early stage, ensuring higher production quality and fewer rejected parts. The Zeiss Contura G2 speeds the inspection process, so we can deliver high quality components to our customers faster.
  • In addition to its use in our quality control procedures, we can use the CMM for reverse engineering existing components or tooling. Once the probe has collected a mass of measurement data points, the system can export this data to the appropriate file format for recreating the shape of the original object.
  • SAS is certified as operating a Quality Management System that complies with the requirements of ISO 13485:2003 and those of ISO 9001:2008 + AS9100C for a contract manufacturer utilizing 5-axis high-speed mills. In addition, SAS is Nadcap certified for Nonconventional Machining in Sinker and Wire EDM.  SAS is also ITAR Registered.
