Certified Quality and Testing

Without Certified Quality Management System you do not have a continuous improving product quality system to consistently and continuously meet or exceed customer requirements. TS is certified to ISO 9001: 2008. TS has been registered by STR-Registrar, LLC, Registration number 09-56938. The documented TS Quality Management System includes product inspection verification throughout its product realization process from receiving, in-process, and final inspection as well as any customer required first article inspection. Positive Material Identification (PMI) monitoring of raw materials and final product is performed on all products manufactured.

TS also certifies its products through its own Testing Laboratory that is compliant to ISO 17025. The TS's Test Lab performs Nondestructive Testing (Magnetic Particle & Penetrant), Tensile Testing, Hardness Testing, Charpy Impact Testing, and Magnetic Permeability Testing. The TS Testing Laboratory includes a Calibration Office that calibrates, controls, and provides repair for approximately 2000 gage's and measuring equipment.

All processes under TS's Quality Management System are monitored and continuously improved to meet and exceed our customer's and regulatory requirements.
We believe QUALITY is paramount in supplying your requirements. You can be assured that we will endeavor to take every care in making sure your components reach you exactly as you expect them.
