One facility.
Every step under one roof.
OEM assembly and contract manufacturing services — build-to-print and turnkey across mechanical, electronic, and integrated systems. Backed by a 300,000 sq. ft. facility in Canton, Michigan, USA.
Contract Manufacturing Services:
Build-to-Print to Fulfillment.
Multiple suppliers mean coordination overhead, schedule slippage, and finger-pointing when something goes wrong. That goes away when every step lives under one roof: engineering, assembly, testing, warehousing, and shipping.
One team, one building, one accountable partner. Your project moves faster because nothing waits at a vendor handoff — and when you call, you reach the team that’s been delivering across the industries we serve for 31+ years.
We protect your IP, and a mutual NDA is guaranteed at every program kickoff — no parallel branded program competing with yours, no joint-venture entanglements. For OEMs comparing offshore vs. domestic CMs, that matters as much as cost or capacity.

- 20,000+ sq. ft. ISO Class 6 & ISO Class 7 cleanrooms (Class 1,000 & Class 10,000)
- Scalable annual assembly capacity
- In-house process engineering, QA, and program management
- ISO 9001 & ISO 14001 certified
What is contract manufacturing?
Contract manufacturing outsources production of finished goods or sub-assemblies to a third-party manufacturer that builds to your specifications under your brand. The contract manufacturer (CM) provides facility, equipment, labor, quality systems, and supply chain. You provide design, BOM, and brand. The OEM keeps engineering and IP in-house; the CM handles physical production.
Two delivery models dominate. Build-to-print services produce exactly to the OEM’s prints and BOM — lowest IP exposure, highest OEM control. Turnkey manufacturing hands the CM sourcing, production, testing, and often fulfillment, returning a finished product. Most OEMs in consumer electronics, industrial controls, medical devices, and emerging-tech run some mix of both.
A contract manufacturing program runs the full sequence: program kickoff, supplier qualification, validation builds, pilot production, full ramp, ongoing quality monitoring, and lifecycle management. Lotus runs all of this from one 300,000 sq. ft. facility in Canton, Michigan, USA, under ISO 9001 + 14001.
- OEM keeps engineering and IP; CM handles physical production
- Build-to-print services for maximum OEM control
- Turnkey manufacturing for reduced operational overhead
- Sub-assembly services and box build assembly available across both models
- High-mix, high-complexity contract manufacturing is a Lotus specialty
What We Build
OEM assembly from final assembly + integration to fully assembled systems. Build-to-print or full turnkey, single units to volume production runs.
Build-to-Print Services
Working from your prints and BOM, we deliver the exact spec you specified. Tight tolerances, full traceability, repeatable production runs across any volume.
Turnkey Manufacturing
End-to-end manufacturing from sourcing through final test. High-throughput lines for large, multi-component assemblies across mechanical, electrical, and electronic disciplines.
Electromechanical Assembly
Fasteners, fixtures, sub-assemblies, and finished products combining mechanical and electrical components. Hand assembly and semi-automated processes for low- to high-volume runs.
Box Build Assembly
Box build assembly integrating PCBs, harnesses, enclosures, and full electronic sub-systems — with component-level wiring, end-of-line functional test, and burn-in capability for OEM contract manufacturing programs.
Cleanroom Operations
20,000+ sq. ft. of ISO Class 6 and ISO Class 7 cleanroom space (Class 1,000 and Class 10,000) for sensitive electronics and contamination-controlled assembly.
Sub-Assembly & Functional Test
Sub-assembly services with in-process inspection, end-of-line functional test, traceability documentation, and rigorous QA on every production run. High-mix, high-complexity programs are a Lotus specialty.
How We Launch a New Program
New programs run through a structured launch — feasibility, planning, pilot, full production, and continuous improvement. Each step is documented, each handoff is measured, nothing ramps until you sign off. Here's what that looks like from your side.
Inquiry & Feasibility Review
Your print, your BOM, your spec — reviewed by our engineering, quality, and program teams together. You get a quote backed by real engineering input, not a pricing spreadsheet.
Program Planning
Before a single unit is built, you get a process flow diagram, control plan, work instructions, and visual standards.
Pilot Production & Validation
We run a pilot under the full control plan. Productivity and first-time-right rates are measured against targets. You sign off before volume release.
Full Production
Volume production runs against the validated control plan. SPC runs on critical dimensions, and every unit carries full lot traceability.
Continuous Improvement & Feedback
When something goes wrong, we root-cause it with your team and close the loop. What we learn goes back into your program — so issue #1 doesn't come back as issue #2.
What We Build Into Every New Program
- Process flow diagram
- Control plan
- Work instructions & visual standards
- Legal and regulatory compliance review
- Pilot run and formal sign-off before full production
Some programs can begin in as little as two weeks — including emergency service for projects that need to start now.
Measurement and Inspection, Built Into Every Run
ISO 9001:2015 certified, with in-process inspection, end-of-line functional test, pre-delivery inspection (PDI) when program spec requires it, and full traceability documentation on every production run.
“Meets spec” is the floor, not the goal. The same measurement rigor runs across our cleanroom operations and post-sale service programs.
- ISO 9001:2015 certified quality management
- In-process and final inspection on every build
- Full traceability documentation
- Continuous improvement (kaizen) embedded in process

Contract Manufacturing FAQ
Contract manufacturing is the practice of outsourcing the production of finished goods or sub-assemblies to a third-party manufacturer (the CM) that builds them to your specifications under your brand. The CM provides the facility, equipment, labor, quality systems, and supply chain. The OEM provides the design, bill of materials, and brand. Most modern OEMs across consumer electronics, industrial controls, medical devices, and emerging-technology sectors use contract manufacturers.
A contract manufacturer is a company that produces goods or sub-assemblies for another company under contract, building to specifications provided by the buyer. The buyer keeps the brand, engineering, and IP; the contract manufacturer owns the production facility, workforce, and process discipline. Lotus is a US contract manufacturer based in Canton, Michigan, USA, ISO 9001 + 14001 certified, NMSDC MBE qualified.
A contract manufacturing engagement runs through a sequence: program kickoff and feasibility review, supplier qualification, validation builds, pilot production, full production ramp, ongoing quality monitoring, and lifecycle management. Inside the facility, the work spans receiving, sub-assembly, electromechanical assembly, box build, functional testing, packaging, and fulfillment — depending on whether the engagement is build-to-print or turnkey.
Build-to-print services have the contract manufacturer produce exactly to the OEM's prints and bill of materials — the OEM owns sourcing decisions and IP exposure is minimal. Turnkey manufacturing has the CM own sourcing, production, testing, and often fulfillment, returning a finished product to the OEM. Build-to-print gives the OEM more control; turnkey reduces operational overhead. Most programs run some mix of both. Lotus supports both delivery models.
