Contract Manufacturing Services for Complex Equipment and Assemblies

PEKO provides contract manufacturing services for OEMs building complex machinery, equipment, assemblies, and integrated systems. When a product requires more than a single supplier, isolated manufacturing process, or basic assembly resource, PEKO helps bring the work into a more controlled, production-ready program.

Custom Contract Manufacturing for Complex OEM Programs

For OEMs evaluating contract manufacturing services, the right partner is not just a supplier with available capacity. Complex equipment, machinery, assemblies, and systems often require coordinated execution across engineering, sourcing, machining, fabrication, welding, assembly, integration, inspection, testing, and logistics. Those requirements need to be managed together if the product is going to move into production reliably.

PEKO is a U.S.-based contract manufacturer that supports complex OEM contract manufacturing programs with vertically integrated capabilities, program management, supply chain coordination, quality systems, and production support. Our team is well suited for custom contract manufacturing programs where technical requirements, documentation, and final product performance all need to stay aligned.

Now more than ever, a common question companies that want to produce and sell machinery, equipment, instrumentation, and other major mechanical assemblies is “How will I make my product?” The investment involved with setting up an entire manufacturing operation is an enormous barrier to making the OEM product in-house. Inevitably, “finding a contract manufacturer” is the answer for many companies. But landing on that square is just the beginning.

Program Fit

When PEKO Is the Right Contract Manufacturing Partner

PEKO’s contract manufacturing services are best suited for OEM programs where the manufacturing requirements extend beyond a single part, process, or supplier. These programs often require coordinated execution across engineering, sourcing, production, quality, and final delivery.

OEMs often come to PEKO when:

  • Internal manufacturing capacity is limited or better used elsewhere
  • A product requires several manufacturing disciplines under one program
  • Supplier fragmentation is creating schedule, quality, or communication challenges
  • A product is moving from development, pilot build, or early production into a more controlled manufacturing process
  • A mature program needs to be transferred from another supplier or internal facility
  • The build requires documentation, inspection, traceability, or final testing
  • The product serves a high-spec or regulated market
  • The OEM needs a U.S.-based contract manufacturing partner with program management and production control

PEKO is a fit for OEMs that need to outsource complex manufacturing while maintaining control over technical requirements, quality expectations, documentation, and program execution.

NPI to Production

Contract Manufacturing Services From NPI to Production

PEKO supports complex contract manufacturing programs at different stages of the product lifecycle. Some customers need help preparing an evolving design for production. Others need a contract manufacturing partner to take over an established build package and support ongoing production.

For early-stage and evolving products, PEKO’s NPI support can help prepare the design, documentation, and manufacturing approach for repeatable production. Support may include:

For mature products, PEKO supports build-to-print contract manufacturing using customer drawings, specifications, BOM, work instructions, and technical requirements. These programs may involve transferring work from another supplier, relocating a legacy product, or moving production out of an internal facility.

In either case, PEKO’s role is to help define and execute the manufacturing path needed to build the product consistently, document the process, and support production requirements over time.

What Full-Service Contract Manufacturing Means for OEM Equipment Builds

Program Support

Program Management, Supply Chain, & Production Control

Complex contract manufacturing programs require clear communication, production planning, supplier coordination, documentation control, and accountability across the full build cycle. PEKO assigns a program manager to each program to serve as a single point of contact. Program managers coordinate across engineering, purchasing, production, quality, and delivery to help keep the work aligned with customer requirements.

PEKO also provides support for:

This structure helps OEMs reduce the burden of managing multiple suppliers while maintaining visibility into production status, quality requirements, and delivery expectations.

Quality & Compliance

Quality Systems for High-Spec OEM Programs

PEKO’s quality management systems support customers with demanding documentation, regulatory, inspection, and traceability requirements.

PEKO is certified through ABS Quality Evaluations to AS9100D, ISO 9001:2015, and ISO 13485:2016. We are also NIST compliant and ITAR registered. PEKO is surveyed and audited more than 20 times per year and continually reviews practices to support quality standards across customer programs.

For machinery, equipment, and integrated systems, PEKO works with OEM stakeholders to define what must be satisfied before a product ships.

What Sets Great Contract Manufacturers Apart From the Rest

FAQs

Frequently Asked Questions About Contract Manufacturing

What Is Contract Manufacturing?

Contract manufacturing is an outsourcing model where an original equipment manufacturer, or OEM, works with a qualified manufacturing partner to build a product, assembly, machine, or system. Instead of managing every production activity internally, the OEM relies on the contract manufacturer to support some or all of the manufacturing process.

Why Choose a Vertically Integrated Contract Manufacturer?

A vertically integrated contract manufacturer can reduce supplier handoffs, improve communication, simplify program management, and give OEMs better control over quality, scheduling, documentation, and production readiness.

Is PEKO A Fit for Low-Volume, High-Mix, Or Complex Contract Manufacturing Programs?

Yes. PEKO is well suited for OEM programs where products are complex, volumes are specialized, and production requirements may vary by build, configuration, or customer demand. Our contract manufacturing services support low-volume and high-mix programs that require engineering coordination, controlled documentation, supply chain management, precision manufacturing, assembly, integration, inspection, and testing.

Can PEKO Support a Product Before It Is Ready for Full Production?

Yes. PEKO can support products during NPI, prototype validation, pilot builds, and early production. Our team can help review designs, validate bills of materials, improve manufacturability, prepare production documentation, and define the process needed for repeatable manufacturing.

Can PEKO Manufacture from Existing Drawings and Bills of Materials?

Yes. PEKO supports build-to-print contract manufacturing for OEMs with existing drawings, specifications, bills of materials, work instructions, and production requirements. PEKO can also review documentation for manufacturing readiness before production begins.

Can PEKO Take Over Manufacturing from Another Supplier or Internal Facility?

Yes. PEKO supports production transfer programs for OEMs relocating work from another supplier, internal operation, or fragmented supplier base. These programs may include documentation review, supplier information transfer, BOM validation, production planning, quality review, and manufacturing process development.

How Does PEKO Manage Quality for Contract Manufacturing Programs?

PEKO supports contract manufacturing programs with quality systems, inspection planning, documentation controls, traceability practices, nonconforming product controls, and final testing requirements. Depending on the program, this may include factory acceptance testing before shipment.

What Should OEMs Prepare Before Contacting PEKO?

Helpful information includes drawings, bills of materials, specifications, forecasted volumes, production history, quality requirements, test requirements, timeline goals, and any known manufacturing or supplier constraints. A complete production package is helpful but not always required for the first conversation.
