Facilities and Equipment

Master Metal Engineering (MME) was established in 1974 in South Bend, Indiana. The company expanded to 35,000 square feet with the acquisition of South Bend Precision in 2009, with two separate facilities housing both manufacturing and administrative offices. Ownership of the business has remained the same since 1996.
