Douglas Machine & Engineering—known as DM&E—is an ISO 9001:2015 and AS9100D certified precision manufacturing company serving aerospace, defense, agricultural, robotics, food-grade packaging, pharmaceutical, construction, and industrial sectors. Built on a foundation of technical excellence and a revitalized commitment to customer service, DM&E operates as a true one-stop shop, managing every project from concept through installation. The company recently celebrated the grand opening of a new CNC Machining production shop, expanding its capabilities and capacity for higher-production-value work. With AWS certified welders, advanced metrology resources, an in-house paint and powder coating facility, and a network of certified supply partners for heat treating and plating, DM&E ensures quality remains in-house at every stage. Their CAGE Code (87BF4), JCP and SAM approvals, and Cyber Security Insurance reflect a company built for demanding, compliance-driven industries.
Heat treating services are controlled heating and cooling processes applied to metals to alter their physical and mechanical properties—such as hardness, strength, ductility, and toughness—without changing the part's shape. DM&E coordinates these services through certified supply partners as part of a fully managed project workflow.
