Precision metal prototype fabrication

Our Prototype Development & Fabrication Services

Prototype-focused fabrication services that support early design, precision manufacturing, assembly, and production scaling.

Product Support

Early-stage engineering support to help customers refine concepts, evaluate manufacturability, and prepare designs for practical fabrication, testing, and eventual production runs.

Custom Fabrication

Customized fabrication for sheet and plate metal at any level, including one-off prototypes, short runs, and production quantities built to customer drawings.

DFM Consultation

Knowledgeable staff assist with cost-effective manufacturing applications, helping reduce part cost, simplify fabrication, and improve repeatability before production begins.

Laser Cutting

Precision cutting for sheet and plate metal, including intricate profiles, tight tolerances, and clean edges across steel, stainless steel, and aluminum.

Forming

Press brake bending creates angles, channels, boxes, chassis components, enclosures, and complex geometries required for functional metal prototypes and assemblies.

Assembly

Mechanical assembly services bring fabricated components together with hardware insertion, riveting, multi-part weldments, chassis systems, and finished unit preparation.

Frequently Asked Questions

What is prototype fabrication?

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.

How much does it cost to get a prototype made?

What types of prototypes can you fabricate?

Can you help improve my design before fabrication?
