Mechanical assembly services for machined, fabricated, and finished components delivered as a complete build.

Total Manufacturing provides mechanical assembly services for components that have completed prior in-house manufacturing operations, including multi-axis CNC milling, turning, precision grinding, wire and sinker EDM, structural welding, custom fabrication, and industrial painting. As a contract manufacturer, completing assembly under one roof avoids the scheduling delays, fitment issues, and transit risk that come with shipping parts between separate machining, welding, painting, and assembly vendors. This includes the capacity to assemble large structural fabrications, heavy weldments, machine bases, and other heavy mechanical builds. Buyers receive the completed assembly along with a single package of documentation covering material traceability and compliance, simplifying supply chain management and providing cost effectiveness and audit readiness compared to coordinating multiple outside vendors. Companies outsourcing assembly to Total Manufacturing, whether through contract assembly services or a single outsourced assembly services project, gain a long-term assembly partner focused on reducing lead time, reducing costs, and simplifying the assembly process from raw components to a final product.

↗FAQs
Have questions? Here are answers to some of the questions we hear most often.
Total Manufacturing applies lean manufacturing principles to reduce unnecessary handling and waste during assembly, using cutting-edge equipment alongside the same machining, fabrication, and finishing capabilities used earlier in the project. This keeps assembly efficient without adding a separate, disconnected step to the manufacturing process.
Outsourcing assembly to Total Manufacturing can generate cost savings by folding assembly into the same production process as machining, fabrication, and finishing on state-of-the-art equipment, rather than adding a separate assembly line to your own manufacturing operations. This approach also reduces waste from shipping, handling, and rework between separate vendors.
Completing assembly in-house avoids the scheduling delays, fitment discrepancies, and transit risk that can occur when parts move between separate outside machining, welding, painting, and assembly vendors. Buyers also receive one unified package of material traceability and compliance documentation with the completed assembly, supporting full audit readiness and increasing efficiency across the project.
Provide the assembly drawing, individual component drawings, a bill of materials, and any work instructions for how the parts should be assembled. If inspection of the completed assembly is required, note that as well so it can be included in the quote.
Assemblies can incorporate machined, fabricated, welded, painted, or finished components produced as part of the broader manufacturing process, with assembly services ranging from small mechanical sub-assemblies to large structural builds. As part of Total Manufacturing's contract manufacturing services, this allows a project to move from raw material to a completed, finished build without changing suppliers, a cost-effective way to keep assembly connected to the rest of the manufacturing process.
