About MTI

In 1926 our founder, Conrad Adams, may not have been able to visualize all the great things ahead for his family’s small tool and die company. However, he could see a bright future solving problems for his customers. Through hard work and a steadfast dedication to solving their most challenging manufacturing problems, the little company from South Bend, Indiana became the world-leader in friction welding technologies, providing engineered solutions from golf putters to jet engines. Today – nine decades and four generations later – MTI’s commitment continues with a solid succession plan and a vision for GREATNESS in place for the next generation.
