From concept through installation, our ISO 9001:2015 and AS9100D certified team brings one-stop-shop manufacturing, tight tolerances, and on-time delivery to every project. Discover what true precision looks like.
Comprehensive CNC machining, fabrication, finishing, and quality services—all managed under one roof from concept to delivery.
Advanced CNC milling, lathe turning, and full-scope fabrication with tolerances as tight as +/-.0005. We machine components up to 20,000 lbs and build structural fabrications up to 20 tons for aerospace, defense, and industrial applications.
In-house design team takes your concept from idea to finished product using PTC Creo, CATIA v5, and AutoCAD. We manage the entire workflow—design, programming, and production—so you have a single point of contact.
AWS certified welders providing precision structural and specialty welding as part of integrated fabrication projects. We support hydraulic and electronic weld tooling, assembly fixtures, and certified weld documentation for regulated industries.
Rigorous ISO 9001:2015 and AS9100D compliant inspection using CMM analysis, first article inspection (FAI) reporting, and certified granite table dimensional verification to ensure every part meets specification.
In-house thermoset powder coating and liquid paint facility with blast preparation. Applies epoxy, polyester, polyurethane, and metallic finishes for corrosion, UV, and abrasion resistance on fabricated assemblies and custom metal parts.
Turnkey design, build, and integration of custom robotic welding and assembly systems. Includes retrofitting existing equipment, full unit testing, and on-site validation to support advanced manufacturing automation.
We start by thoroughly understanding your project scope, material requirements, tolerances, and delivery timelines. Our team establishes open communication from day one, ensuring Minnesota manufacturers and national OEMs receive a clear, transparent project plan.

Douglas Machine & Engineering—operating as DM&E—is a Minnesota-area precision manufacturing partner serving aerospace, defense, agricultural, robotics, pharmaceutical, food-grade packaging, and industrial sectors. Built on a foundation of craftsmanship and continuous improvement, DM&E recently marked a significant milestone with the grand opening of a new CNC machining production shop, expanding capacity and production value for customers across the Midwest and beyond. Holding ISO 9001:2015 and AS9100D certifications, JCP and SAM approvals, and a CAGE Code (87BF4), the company is positioned to serve the most demanding regulated industries. DM&E's core values center on transparent communication, comprehensive project ownership, and an open-door policy that ensures customers are informed and confident from the first conversation to final delivery.
Contract machining means you outsource your component manufacturing to a specialized shop like DM&E rather than producing parts in-house. We handle design, programming, machining, finishing, and quality verification—delivering finished parts to your specification while you focus on your core business.
Our engineering team is ready to discuss your project requirements and provide a tailored solution.
International standard for quality management systems
