Comprehensive fabrication support from raw sheet and plate through welded, finished, production-ready assemblies for demanding industrial buyers.
Custom sheet and plate components are built to customer drawings, supporting prototypes, short runs, and production quantities for demanding commercial and industrial applications.
Precision laser cutting creates intricate profiles, tight-tolerance features, and clean edges across steel, stainless steel, and aluminum sheet or plate materials.
Press brake forming shapes metal into angles, channels, boxes, enclosures, and complex geometries used in chassis, panels, and mechanical assemblies.
Welding services join fabricated components for structural strength, cosmetic appearance, sealed enclosure needs, weldments, chassis systems, and finished assemblies.
Numerically controlled turret punching produces holes, cutouts, louvers, and formed features efficiently, especially for repeatable patterns and production volumes.
Mechanical assembly support includes hardware insertion, riveting, multi-part weldments, chassis systems, and finished units prepared for customer integration.

Your drawings, quantities, materials, tolerances, and application requirements are reviewed for manufacturability. The team can recommend cost-effective adjustments before work begins, helping reduce revisions, wasted material, and production surprises later.

Ron Nunes Enterprises began in 1969 when Ron Nunes recognized the need for manufacturing services that could support a wide range of practical applications. More than 55 years later, the Livermore, California company continues to provide precision metal products for commercial, industrial, and specialized markets. Its capabilities have grown with changing customer requirements, serving communications, telecommunications, transportation, nuclear and physics research, national defense, semiconductor, medical, and other demanding sectors. The company’s vision remains focused on manufacturing excellence: pairing full-service fabrication capabilities with knowledgeable support, cost-effective applications, and dependable production scheduling for customers who need a long-term metal manufacturing partner nationwide.
Sheet metal companies turn flat metal sheets or plates into usable parts, enclosures, brackets, chassis, panels, and assemblies. Typical work includes cutting, punching, bending, welding, finishing, and inspection. Ron Nunes Enterprises also supports product development and DFM, helping customers move from drawings or prototypes into cost-effective production runs with fewer revisions.
