The History of Mac-Mold Base

MMB was established in 1990 and is located in Romeo, Michigan. Our experience in the mold manufacture industry is over 30 years. We occupy three modern facilities. Plant 1 is our main headquarters where machining, assembly and staging takes place. Plant 2 stores and processes raw material and allows us to cut, grind, and rough more efficiently. In 2011 we opened Plant 3, adding a brand new double column vertical bridge mill and 20 ton crane, making our total shop capacity over 27,000 sq. ft. In April of 2011, we celebrated 21 years of business. We recently purchased a brand new mill and added the capability of waterjet cutting to stay competitive and diverse. Our team consists of experienced engineers paired with a highly trained and motivated group of CNC Machine operators, backed up by our inspection department that is precise and trained to assemble quality mold bases.
