Product Support
Early-stage engineering support to help customers refine concepts, evaluate manufacturability, and prepare designs for practical fabrication, testing, and eventual production runs.
Turn early concepts into manufacturable metal parts with prototype development and fabrication support from Ron Nunes Enterprises. From DFM consultation and precision cutting to forming, welding, finishing, and assembly, our team helps refine designs, reduce production risk, and build reliable parts for commercial, industrial, transportation, defense, medical, and technology applications.

Prototype-focused fabrication services that support early design, precision manufacturing, assembly, and production scaling.
Early-stage engineering support to help customers refine concepts, evaluate manufacturability, and prepare designs for practical fabrication, testing, and eventual production runs.
Customized fabrication for sheet and plate metal at any level, including one-off prototypes, short runs, and production quantities built to customer drawings.
Knowledgeable staff assist with cost-effective manufacturing applications, helping reduce part cost, simplify fabrication, and improve repeatability before production begins.
Precision cutting for sheet and plate metal, including intricate profiles, tight tolerances, and clean edges across steel, stainless steel, and aluminum.
Press brake bending creates angles, channels, boxes, chassis components, enclosures, and complex geometries required for functional metal prototypes and assemblies.
Mechanical assembly services bring fabricated components together with hardware insertion, riveting, multi-part weldments, chassis systems, and finished unit preparation.

Founded by Ron Nunes in 1969, Ron Nunes Enterprises was created to meet the growing need for manufacturing services across a wide range of applications. From its Livermore, California headquarters, the company has served precision, commercial, and industrial markets for more than 55 years. Its work has expanded across communications, telecommunications, transportation, nuclear and physics research, medical, semiconductor, and national defense applications. Today, the team remains committed to manufacturing excellence through practical engineering support, cost-effective fabrication methods, and custom metal solutions that help customers move confidently from product development into reliable production.
Prototype fabrication is the process of creating a physical part, enclosure, chassis, bracket, or assembly from an early design or engineering drawing. In metal fabrication, it can include DFM review, material selection, laser cutting, punching, forming, welding, finishing, and assembly. The goal is to validate fit, function, manufacturability, and cost before moving into larger production quantities.
