Quality Control

Sons Tool, Inc. is dedicated to providing our customers and co�workers with parts that conform exactly to specified requirements. In todays global business world of custom manufacturing, quality is no longer anticipated, but is demanded by everyone, and we have met that challenge. Our quality rating for the past 15 years has averaged 98.8% and for the past 5 years 99.25%.

Quality Control Department

Our Quality Control department co-ordinates with engineering and production in setting up initial inspection reports and variable data charts for all critical dimensions for every new part entered into our system. To insure that all quality standards are met on every repeat order our system automatically downloads these established procedures.

Maintaining High Quality Standards

We use variable data charts to specify how often every operation is to be inspected once they have been initially approved by the quality department. Once all operations have been successfully completed parts go through a final inspection before being shipped. Every process and procedure is documented; F.A.I.R.' s, PP AP' s, ISIR's, SPC, CofC, capability studies, material, plating, painting, heat treat certifications etc. All of our inspection equipment is calibrated to the N.I.S.T. standards.
