Precision metal kitting and assembly

Our Kitting & Assembly Services

Integrated fabrication, kitting, and assembly support for production-ready metal components, chassis systems, and OEM supply programs.

Mechanical Assembly

We assemble fabricated metal components into finished units using hardware insertion, riveting, weldments, and chassis integration, helping customers reduce internal labor and receive parts ready for the next production stage.

Kitting Programs

Organized component kits package fabricated parts, hardware, and related assembly elements together so manufacturing teams can simplify receiving, control inventory, and maintain repeatable builds across recurring production needs.

OEM Manufacturing

Production runs, scheduling integration, fabrication, and assembly support position Ron Nunes Enterprises as an ongoing contract supplier for OEMs needing reliable metal manufacturing capacity.

Development Support

Staff assistance during product development helps customers refine designs, improve manufacturability, and reduce part costs before moving into prototype, short-run, or full production assembly programs.

Component Fabrication

Laser cutting, shearing, N/C punching, forming, welding, and finishing preparation create the precise metal components required for repeatable kits, assemblies, chassis systems, and specialized industrial products.

Scheduling Integration

Production schedules can be aligned with customer supply chains and delivery cadence, supporting contract manufacturing programs that depend on predictable releases and ongoing assembly availability.

Frequently Asked Questions

What is kitting and assembly?

Kitting is the process of organizing all required components, hardware, and related materials into complete sets for a build or production run. Assembly is the next step, where those components are joined into finished parts, subassemblies, chassis systems, or mechanical units. Together, kitting and assembly reduce handling, simplify inventory control, and help production teams receive more complete, ready-to-use deliverables.
