Mechanical Engineering Services for Complex OEM Programs
PEKO provides mechanical engineering services for OEMs that need support designing, refining, documenting, transferring, or manufacturing complex physical products. Our team supports machinery, equipment, precision assemblies, test systems, mechanical hardware, and electromechanical products where fit, function, structure, manufacturability, documentation, and production execution all need to stay aligned.
As part of PEKO’s broader engineering services, our mechanical engineering support is tied to real manufacturing programs. We help customers evaluate mechanical design details, update CAD models, verify bills of materials, prepare production packages, support GD&T requirements, and resolve mechanical issues that could affect build quality or long-term production.
PEKO’s mechanical engineering group includes more than 20 mechanical engineers and technicians who support complex OEM manufacturing programs. The team works with 3D modeling platforms such as CREO, SolidWorks, and Inventor to support CAD modeling, drawing updates, mechanical design review, and production documentation.
PEKO’s mechanical engineering services may support new product introduction, production transfer, custom equipment builds, or mature OEM programs that need mechanical design refinement, documentation updates, or manufacturing-connected engineering support.
Mechanical Design Engineering Support Connected to Manufacturing
Mechanical design decisions affect how a product is built, assembled, tested, serviced, inspected, and supported in production. For complex OEM programs, details such as component layout, mounting strategy, access, structure, motion, tolerances, materials, fasteners, and documentation can all influence manufacturing outcomes.
PEKO’s mechanical design engineering support helps connect those details to the realities of contract manufacturing. Our mechanical engineers work with manufacturing, quality, assembly, controls, test, tooling, and program teams to help customers move from design requirements to a more complete production-ready package.
This approach is especially useful for OEMs that need mechanical product engineering services connected to manufacturing execution, not isolated design recommendations.
When OEMs Use PEKO’s Mechanical Engineering Services
OEMs often involve PEKO when a mechanical design, equipment program, or build package needs to move closer to production. This may happen during new product introduction, production transfer, custom equipment development, or ongoing manufacturing support.
Common triggers include:
- A design is technically viable but needs production-focused mechanical review.
- A prototype or pilot build has revealed fit, access, tolerance, or assembly issues.
- A machine, fixture, test system, or assembly needs mechanical updates before repeatable manufacturing.
- A production transfer requires review of drawings, models, bills of materials, and mechanical requirements.
- A mature product needs component changes, documentation cleanup, or mechanical re-engineering.
- A contract manufacturing program needs engineering support tied to build quality, inspection, testing, or production release.
PEKO helps reduce design ambiguity, identify mechanical risks, and support the engineering work needed to manufacture complex products with consistency.
Mechanical Engineering Support Areas
PEKO’s mechanical engineering services may include support for:
- CAD Model & Drawing Support: Updating, refining, or creating CAD models and drawings using 3D modeling platforms such as CREO, SolidWorks, and Inventor so production teams have accurate technical information for manufacturing, inspection, and assembly.
- BOM Review & Mechanical Documentation: Reviewing bills of materials, component details, drawing packages, and related documentation to identify missing, outdated, or inconsistent information.
- Mechanical Design Refinement: Supporting design updates related to fit, function, structure, mounting, component layout, service access, and production requirements.
- GD&T & Production Release Support: Supporting geometric dimensioning and tolerancing, critical features, print packages, and other mechanical documentation needed for production release.
- Equipment & Machinery Engineering: Providing mechanical engineering support for custom machinery, automation equipment, test systems, production equipment, and other complex OEM products.
- Fixture, Tooling, & Build Support: Providing mechanical input for fixtures, tooling, test fixtures, mechanical interfaces, and build-support hardware used during production or validation.
How Mechanical Engineering Supports Contract Manufacturing
Mechanical engineering support becomes more useful when engineers can evaluate a design with input from the teams responsible for building it. In a contract manufacturing program, mechanical details may affect machining, fabrication, welding, assembly, controls integration, inspection, testing, packaging, and service access.
PEKO’s mechanical engineers work with production, quality, supply chain, test, and program teams to help resolve mechanical questions before they become build issues. This can include CAD updates, drawing revisions, BOM review, fixture input, tolerance review, and mechanical design changes tied to the product’s manufacturing requirements.
For OEMs looking to outsource mechanical engineering services, PEKO is best suited for work that needs to connect engineering decisions with production execution.
