Quality stands at the center of everything we do at L.H. Thomson – with a calibration system boasting over 2,500 gages, a skilled quality department, and delegated inspectors, we give superior attention to each project. Our attention to quality has made us a trusted and leading manufacturer of flight critical parts for over 30 years.


From the time raw materials are received, our inspection system begins. Our calibration system includes custom manufactured gages, and our highly trained and experienced engineers ensure each project is precisely to specification. Each floor operator is individually responsible for his/her own projects. In fact, our quality standards were recognized as being so high by one of our customers, that many of our operators have been granted delegated inspector status. Our operators check the first part 100% at the machine. Your project is in the hands of very skilled and experienced engineers and machinists.

Our Quality Management System is certified as being in conformity with AS9100 by Intertek. We are also a Boeing Silver Certified supplier, creating many of their flight critical parts, which requires the utmost attention to detail. At Thomson, we are constantly enhancing capabilities through continuous improvement and engineering innovation, ensuring our clients receive the highest quality products.
