Don and Mimi Dorsey founded SignaMold & Design, LLC to restore the standard of a product that has been supplanted by foreign firms and other companies that have forgotten the fine craftsmanship of a Custom Tool Shop.

​

The origin of the term "SignaMold" can be traced back to Mimi's parents, who founded Signicast in Milwaukee, Wisconsin. In the 1950s and the first half of the 1960s, Mimi's father worked as a mould maker and machinist. After her father's death, her mother took over the company, which she eventually sold in the mid-1960s.

Don has nearly 40 years of experience in this field. He got his start in this industry thanks to his father-in-law, a toolmaker who taught him the craft. Don may come to mind from Aus-Tech Mold.
