About Us

Our Philosophy

Everyone within our organization impacts quality. It is a responsibility that is carried throughout our factory at every level. It starts with our attitude towards customers, suppliers and colleagues and is implemented in every step of the manufacturing process. We instill an environment wherein all our employees take pride and ownership in the quality of the parts they manufacture. This dedication to quality keeps us consistently ranked in our customers’ “Top Vendor Ratings.”


We manufacture all parts in compliance with our ISO 9001:2015 certification. Our production team is hands-on throughout the entire manufacturing process, utilizing APQP methodology throughout our processes and procedures. This enables us to produce the highest quality products consistently on time and to continually improve at every level of our company.

Packaging and Shipping

Each part that leaves US Cotronics is given a final inspection before being packed to ensure no product leaves our facility until it meets our strict quality standards. We work with all customers to ensure their parts are packed and shipped in the safest, most reliable and most cost-effective manner to guarantee that shipments arrive on-time and undamaged.
