Private-equity firm Auxo Investment Partners acquired Midway Rotary Die Solutions of Williamston, Mich. Midway designs, manufactures and sharpens dies for customers in the automotive and medical industries. The company offers multi-stage heat-treatment processes and cryogenic-treatment services. Midway adds deeper capabilities to Auxo's die-manufacturing platform, which includes Bernal Rotary Dies, Atlas Die and Atlas Chem-Milling.

The deal will allow Midway to serve a wider array of customers and offer its existing customers new capabilities in wide-format RP rotary dies and flexible rotary dies. According to Grand Rapids, Mich.-based Auxo, combining Midway with its existing portfolio of die producers will enable the company to offer customers an increasingly broad suite of capabilities.
