Link Engineering

Link Engineering Company (LINK) has been committed to cultivating positive growth and advancing the testing industry since our founding in 1935. Founded by Herbert Link in Detroit, Michigan, LINK started as a manufacturer and supplier of spring testing devices. In 1950, LINK expanded into the cutting tool industry and founded Link Industries, which is still in operation today.

Through the 1960s to today, LINK has been at the forefront of the testing industry, and partner to global OEMs and suppliers. In 2017, LINK further expanded our testing capabilities to thermal testing solutions, with the acquisition of Tescor, a global manufacturer of climatic testing equipment for the automotive, HVAC, pharmaceutical, and life sciences industries.

Link Group, Inc., headquartered in Plymouth, Michigan, is the parent company to Link Engineering Company, Link Industries, and Tescor, and is the corporate entity that oversees and supports all business operations..


With decades of testing experience in brakes, wheel-end, transmission & driveline, springs, steering, and servo-dynamic applications, LINK is a trusted global testing partner with a vast knowledge base. LINK’s specialty has always been developing innovative custom solutions.

As the gold standard in testing for more than 85 years, LINK brings decades of hands-on experience and out-of-the-box thinking to our customers worldwide.


As an active participant or technical lead on numerous global industry working groups, we’ve helped establish many of the test specs and methodologies that have become universal standards. We are always pushing the envelope into emerging technologies, and consider it our responsibility to spearhead industry initiatives for the benefit of all.

We look forward to continuing that evolution, bringing smarter and more innovative testing solutions to industry everywhere.
