Full-service metal fabrication, precision cutting, forming, welding, finishing, and assembly for industrial applications.
Custom sheet and plate components are fabricated to customer drawings, supporting precision commercial and industrial applications that require accurate dimensions and repeatable production quality.
Laser cutting produces clean edges, intricate profiles, and tight-tolerance shapes across steel, stainless steel, and aluminum for prototype and production fabrication needs.
Numerically controlled punching creates holes, cutouts, louvers, and formed features efficiently, especially for repetitive patterns where speed and cost control matter.
Press brake forming bends sheet metal into angles, channels, boxes, chassis parts, and complex geometries used in enclosures and mechanical assemblies.
Welding joins fabricated components for structural strength, sealed joints, cosmetic requirements, enclosures, chassis systems, and multi-part industrial weldments.
Mechanical assembly includes hardware insertion, riveting, chassis integration, and multi-part buildouts so customers can receive finished units ready for use.

The process begins with customer drawings, specifications, quantities, and application requirements. The team reviews the part or assembly for material fit, tolerance needs, production method, and cost-effective manufacturing opportunities before work moves forward.

Founded by Ron Nunes in 1969, Ron Nunes Enterprises was built to support customers who needed reliable manufacturing services across a wide range of applications. From its Livermore, California headquarters, the company has grown into a minority-owned, full-service precision metal fabrication manufacturer serving precision, commercial, and industrial markets. Its work supports communications, telecommunications, transportation, nuclear and physics research, national defense, medical, and semiconductor customers. The company’s vision remains grounded in manufacturing excellence: helping customers move from product development to cost-effective production with knowledgeable support, practical fabrication capabilities, scheduling integration, and custom solutions for diverse applications.
In mechanical work, fabrication means turning raw metal into functional parts, structures, or assemblies through operations such as cutting, shearing, punching, forming, welding, finishing, and assembly. For Ron Nunes Enterprises, that can include precision sheet and plate components, rack mount chassis, hardware insertion, weldments, and production-ready mechanical assemblies built to customer drawings.
