Bring complex metal components from concept to production with custom fabricated products tailored to your drawings, tolerances, and schedule. Ron Nunes Enterprises combines decades of precision sheet and plate fabrication experience with laser cutting, forming, welding, assembly, finishing, and manufacturing support to help OEMs, industrial teams, and public-sector buyers source reliable parts with confidence efficiently.

From prototypes to production runs, our fabrication capabilities support complex metal parts, assemblies, and rack chassis.
Prototype-to-production fabrication for sheet and plate metal parts built around customer drawings, quantities, tolerances, and application requirements for industrial and OEM programs.
Custom-fabricated precision sheet and plate components are built to customer specifications, supporting complex metal parts for commercial, industrial, and specialized technical applications.
Precision laser cutting creates intricate profiles, tight tolerances, and clean edges across steel, stainless steel, and aluminum sheet or plate components.
Press brake forming turns sheet metal into angles, channels, boxes, chassis structures, and complex geometries needed for durable fabricated products.
Welding services join fabricated metal components for structural strength, cosmetic appearance, sealed enclosures, weldments, and production-ready assemblies.
Mechanical assembly includes hardware insertion, riveting, multi-part weldments, chassis systems, and finished units that are ready for integration or shipment.

We review your prints, CAD files, tolerances, material needs, and quantities to understand form, fit, and function. Our team also identifies manufacturability opportunities that can reduce cost before the first cut.
