Turnkey Assembly for Complex OEM Builds
PEKO is your trusted, single-source partner for turnkey assembly services. From simple sheet metal paneling with mounting hardware to complex, multi-component machinery, we offer customized assembly programs that emphasize consistency, traceability, and long-term collaboration, purpose-built for OEMs looking to outsource thousands of labor hours annually. Our vertically integrated operations cover every stage of the build—sourcing, fabrication, assembly, and testing—under one roof, ensuring seamless execution from initial quote through final delivery.
What Turnkey Assembly Services Mean for OEMs
Turnkey assembly is a fully outsourced production model that allows OEMs to offload their entire assembly process. Instead of coordinating multiple suppliers and production stages in-house, OEMs simply hand off their design files, technical documentation, and requirements to a single, trusted contract manufacturing partner, like PEKO.
This partner takes full responsibility for delivering a complete, production-ready system or assembly—built to spec and ready for deployment, installation, or final integration. This approach is particularly beneficial for OEMs facing obstacles managing complex assemblies within their own facilities, like limited internal resources, disjointed supply chains, quality control issues, and scaling difficulties.
Why OEMs Choose PEKO for Turnkey Assembly
OEMs are under constant pressure to deliver complex, high-quality products—faster, leaner, and under strict regulatory requirements. That’s where PEKO comes in.
Our turnkey assembly services manage your project from start to finish, integrating custom-fabricated components into complete subassemblies and fully functional systems—all under one roof.
The PEKO Advantage:
- Free Up Internal Resources: Outsourcing assembly, subsystem, and module-level builds to PEKO allows your internal engineering and operations teams to stay focused on driving product performance and strategic growth—not chasing parts or managing complex builds.
- Eliminate Supply Chain Headaches: Say goodbye to juggling multiple suppliers, POs, and vendor timelines. PEKO’s turnkey assembly services simplify complex manufacturing projects by consolidating responsibility, communication, and execution under one roof.
- Fulfill Low-to-Mid Volume Demand: PEKO’s capabilities are optimized for high-mix, low-to-mid volume assembly, where flexible manufacturing processes, robust documentation controls, engineering-driven quality systems, and repeatability matter more than throughput.
- Safeguard Sensitive Programs: All assembly work is performed at our 400,000 sq ft campus in Rochester, NY, ensuring responsiveness, IP security, process oversight, quality control, and supply chain reliability for sensitive or regulated applications.
- Optimize Designs for Success: Our engineers work closely with you during design transfer and early production, offering critical DFMA input to ensure your product is optimized for cost-effective, repeatable, and scalable production.
- Achieve Consistent, Audit-Ready Results: We are certified to ISO 9001, ISO 13485, and AS9100, and are ITAR-registered—ensuring every assembly meets the highest standards of compliance and performance across your entire program lifecycle.

Our state-of-the-art manufacturing facility houses a wide range of technical capabilities that enable us to handle turnkey assembly projects of varying complexity, size, and configuration, offering end-to-end execution that scales resources as needed:
- Comprehensive engineering support, including DFMA reviews and prototype development
- In-house sheet metal, machining, welding, and painting of complex metal components
- BOM sourcing, procurement, supply chain coordination, and inventory management
- Mechanical and electromechanical assembly of complex assemblies, systems, and machinery
- Functional testing, verification protocols, and quality assurance throughout all phases
- Custom packaging, labeling, logistics coordination, and direct-to-customer fulfillment
The result? A fully assembled and tested product—ready for deployment or final integration.
Engineering-Driven Process
Our approach to turnkey assembly extends beyond technical expertise — it includes a disciplined process for project execution that ensures predictability and success from quotation to delivery:
- Dedicated assembly areas configured for project-specific needs and optimal workflows
- Development of detailed work instructions, process flows, and quality checkpoints
- Rigorous internal training programs to align personnel with program-specific requirements
- Design and fabrication of custom tools, jigs, and fixtures for precision and repeatability
- Full documentation and traceability across all assemblies and hardware components
Custom Engagement Models
Every OEM has different needs. That’s why PEKO offers two core turnkey assembly models:
Partial Turnkey
In this model, clients supply some of the necessary materials or components while we manage any remaining procurement, fabrication, and assembly. This option is ideal for OEMs who want to maintain control over specific aspects of production and preserve their existing supplier relationships while still leveraging our manufacturing and assembly expertise.
Full Turnkey
For OEMs looking to completely offload production duties, we offer full turnkey assembly. In this arrangement, we assume total ownership of the project, managing every aspect from start to finish. This not only simplifies your operations but also significantly reduces your internal workload and supply chain risks, allowing your team to focus on core business activities.
Industries We Work With
Our turnkey assembly services are trusted by OEMs across a broad range of industries—especially those requiring complex, high-precision builds. Our primary expertise lies in the assembly of mechanical and electrical subsystems—including custom enclosures, wire harnesses, PCB assemblies, motors, sensors, pneumatics, and more—all engineered to meet tight tolerances and demanding performance specs.
- Custom industrial automation and material handling equipment
- Medical equipment and laboratory diagnostic machines
- Defense and aerospace systems with strict configuration needs
- Semiconductor and clean-tech systems with contamination controls
How Much Does Turnkey Assembly Cost At PEKO?
Pricing for turnkey assembly is determined on a case-by-case basis, as each program involves a unique combination of product, volume, and service requirements. We provide quotes tailored to your specific assembly scope and production expectations. Factors that influence pricing include:
- Floor Space Requirements → How much dedicated space is needed to stage and build the assemblies
- Volume & Production Cadence → One-time builds vs. recurring, forecasted programs
- Product Value & Complexity → Higher-value products often require tighter controls, documentation, or precision
- Assembly Labor Hours → The number of skilled technician hours required per unit
- Regulatory or Industry Requirements → Medical, defense, and aerospace programs may require additional steps or certifications
- Material Management → Whether components are purchased by PEKO or consigned by the customer
Each quote includes a review of your BOM, drawings, and testing scope, and we work closely with your team to optimize cost, reduce risk, and meet your goals.
