Whether you need precision subassemblies, integrated modules, or fully turnkey electromechanical systems, our mechanical assembly contract manufacturing solutions are designed to deliver exceptional performance at every level of complexity.
- Customized mechanical parts assembly workflows for specialized applications
- Seamless integration into larger system contract manufacturing & assembly programs
- Engineered for durability, consistency, and reliability in complex, multi-component systems
Our Proven Process
Our experts assemble frames, panels, enclosures, and mechanical subassemblies as part of broader system builds, customizing every workflow to align precisely with your specifications and ensure seamless part integration, dimensional accuracy, and structural integrity.
- Close Collaboration → We work closely with your engineers to ensure mechanical assembly plans align with your design intent and system functionality. We also help identify opportunities for improved manufacturability, performance, and cost-efficiency.
- Component Fabrication → Using cutting-edge CNC laser cutting, milling, turning, punching, and bending, we fabricate high-precision sheet metal and machined components in-house. Every part is built to exact specifications to support smooth metal parts assembly.
- Metal Parts Assembly → We bring components together using optimal fastening, welding, or adhesive techniques, ensuring each unit is assembled with the accuracy and consistency needed to perform within the final system.
- Testing & Verification → Each mechanical assembly undergoes rigorous inspection to confirm proper alignment, dimensional tolerances, and mechanical integrity, guaranteeing form, fit, and function before final system integration.
- Final Integration & Delivery → Once complete, mechanical assemblies are prepared for next phase of integration within our facilities or packaged and delivered for install at your final integration point.
We take a hands-on approach through every step—offering insight, expertise, and accountability to help ensure your mechanical assembly project is executed flawlessly.
Integrated Solutions for Full-System Builds
PEKO’s mechanical assembly services are not standalone offerings—they are part of an integrated contract manufacturing ecosystem, serving as the foundation for our on-site motion control, enclosure, subsystem, and full-system integration programs.
- Engineered for Full-System Integration → Our mechanical assembly services seamlessly support our contract manufacturing and assembly programs, aligning all motion, structural, and fastening components into a cohesive unit ready for integration into higher level assemblies and full system builds.
- Customized for Industry-Specific Needs → We tailor each metal assembly to the specific regulatory, environmental, and performance requirements of your industry, ensuring complete compatibility with your system’s mechanical, electromechanical, and structural requirements.
- Built for Long-Term Reliability → Durability and reliability are at the core of our assembly philosophy. We focus on repeatability, precision, and robust construction to ensure that every mechanical sub-assembly we build performs flawlessly within its larger system.
