About Us

HMC International Div., Inc. was founded by Graham W. “Gray” Howard (1907–1995), a mechanical engineer whose career spanned from international projects in Central America and the West Indies to industrial work with Gates Rubber Company in Colorado.

​

In Littleton, Colorado, Howard applied his expertise to creating specialized mechanical instruments, pioneering the development of belt-tension testers and related devices that earned multiple U.S. patents. His focus on precision, reliability, and practical design laid the foundation for HMC International’s reputation.

​

Today, HMC International continues Howard’s legacy, delivering dependable, American-made instruments built on the same engineering ingenuity and commitment to quality that defined its founder.
