Addison Machine Engineering

What Addison Machine Engineering does

Addison Machine Engineering, Inc. is a privately held, family-owned industrial machinery manufacturer founded in 1965 in Addison, Illinois and now headquartered in Reedsburg, Wisconsin. The company designs, engineers, and manufactures custom tube mill systems, roll forming production lines, roll tooling, weld boxes, raft assemblies, and straightener rolls for tubular and roll form producers serving automotive, oil & gas, and broader metal-forming industries. Its product portfolio spans TIG Welded and High-Frequency Tube Mill Systems (sizes AM-0750-TW through AM-5000-HF, covering 0.125" to 6.000" tube diameters), a full suite of mill components (entry guides, driven/idle stands, weld boxes, scarfing units, turksheads, bead winders), and roll forming equipment supported by in-house COPRA FEA simulation and 3D Inventor CAD design.

Under the DBA "Addison Tubular & Roll Forming Solutions," the company operates two Reedsburg facilities — the original Corporate, Engineering & Manufacturing site at 1301 Industrial St and a second Assembly & Testing facility at 605 S Albert Ave opened in 2024 — supported by Mazak CNC lathe and Haas VF-5 milling capacity with turning capability up to 53-inch diameter rolls. Revenue is generated primarily through one-time, quote-based sales of custom equipment and replacement components, complemented by reconditioning and rebuild services on the installed base. Terms are F.O.B. seller's plant with progress payments during manufacturing and quotes valid for 30 days.

The company sells direct to mid-market and enterprise tubular and roll form producers via phone and email (888 AME-ROLL / [email protected]), supported by industry trade show presence (notably Fabtech), LinkedIn, YouTube, Facebook, and direct relationship marketing. End markets include automotive (tubular components for frames, exhaust, structural members; roll formed trim), oil & gas (OCTG, casing, line pipe structural tubing), and general manufacturing (mechanical steel tubing, structural tubing, custom profiles). The Brunken family retains multi-generational control with Patrick Brunken Sr. as Vice President representing the fourth generation, and no external investors, PE/VC backers, or public-market participation are disclosed.
