Douglas Machine & Engineering is built around the promise of “Precision Manufacturing from Concept to Installation.” The company’s skilled workforce supports customers through careful planning, clear communication, in-house design, CNC machining, fabrication, finishing, inspection, and coordinated supplier management. Recent growth includes the grand opening of a new CNC Machining production shop, expanding capacity for higher production value work. With ISO 9001:2015, AS9100D, AWS certified welders, JCP approval, SAM approval, and CAGE Code 87BF4, Douglas Machine & Engineering serves demanding sectors such as aerospace, defense, robotics, agriculture, pharmaceuticals, food grade packaging, construction, and industrial manufacturing.
Custom manufacturing means producing parts, assemblies, fixtures, tooling, finishes, or automated systems to meet a customer’s specific drawings, performance needs, materials, tolerances, and delivery requirements. Instead of standard off-the-shelf production, Douglas Machine & Engineering builds the process around the project, from concept and design support through machining, fabrication, inspection, finishing, and installation.
