From our first certification of BS5750 in 1986 to the current ISO 9001:2015, STL has understood and implemented the improvements in product and process quality, as they became available. Quality is the philosophy at the heart of what we do.

Measurement techniques

Product specification and batch to batch reproducibility are assured by the use of standard quality processes and measurement tools.

  • Advanced product quality planning (APQP)
  • Product part approval process (PPAP)
  • Design and Process FMEA
  • Design verification and validation
  • Design for six sigma manufacturing
  • Statistical techniques – preliminary process capability studies (PPK)
  • Ongoing process capability evaluation (CPK)
  • Performance measurement
  • Keyence Image Dimension Measuring System
  • Laser scanning
  • 3D CMM with both vision system and touch probes with reverse engineering capability.
