Expert Custom Metal Fabrication Shops & Services

Custom fabrication is the process of designing, cutting, machining, welding, forming, finishing, and assembling metal parts or structures to meet a specific application rather than using a standard off-the-shelf product. At DM&E, custom fabrication can include CNC machining, AWS-certified welding, fixtures, tooling, structural assemblies, coating, inspection, and supplier-coordinated processes like plating or heat treating.

A fabrication shop turns raw metal, drawings, and project requirements into finished parts, assemblies, tools, or structures. Depending on the shop’s capabilities, this may involve engineering support, CNC machining, welding, forming, blasting, coating, inspection, assembly, and delivery coordination. Douglas Machine & Engineering provides a broader concept-to-installation workflow for industrial and regulated manufacturing customers.

Douglas Machine & Engineering supports industrial, aerospace and defense, pharmaceutical, agricultural, robotics, food-grade packaging, and construction customers. The company’s certifications, inspection resources, AWS-certified welding, CNC machining capacity, finishing support, and program management capabilities make it well suited for complex parts, large assemblies, production tooling, robotic systems, and specification-driven metal fabrication programs.

Yes. DM&E combines advanced CNC machining with full-scope fabrication services, including precision milling, lathe turning, specialty welding, structural fabrication, fixtures, tooling, and assembly support. The shop can machine components up to 20,000 lbs and build structural fabrications up to 20 tons, helping customers consolidate work that might otherwise require multiple vendors.

Douglas Machine & Engineering’s CNC machining capabilities support tight tolerances ranging from approximately +/-.005 to +/-.0005, depending on the part geometry, material, feature requirements, and inspection method. Projects are reviewed before production so the team can align machining strategy, fixturing, quality checks, and documentation with the tolerance requirements of the finished component.

Yes. DM&E offers in-house paint and powder coating, including thermoset powder finishes, liquid coatings, and blast preparation. The company also coordinates plating and heat-treat processing through qualified partners when required. This integrated finishing support helps improve corrosion resistance, durability, conductivity, wear performance, coating adhesion, and compliance with project-specific material or finish specifications.

Quality assurance is built into the project workflow from concept through delivery. DM&E uses inspection resources such as first article inspection reporting, CMM analysis through Exact Metrology, dimensional verification, certified granite tables, gauges, and comprehensive quality documentation. ISO 9001:2015, AS9100D, JCP, SAM, and AWS welding credentials further support regulated and high-performance manufacturing requirements.

Yes. When a project requires processes not completed in-house, such as plating or heat treating, DM&E coordinates with qualified suppliers and manages those steps within the overall program. This helps reduce transportation costs, simplify purchasing, maintain accountability, and ensure the final part or assembly meets the required functional, metallurgical, and documentation standards.
