Our Capabilities

Rapid Prototyping Capabilities for San Leandro Teams

San Leandro is known for East Bay advanced manufacturing district with OSIsoft data tech and robotics startup prototyping facilities. We handle the precision machining these industries demand.

CNC Milled Prototypes

Flat, prismatic, and sculpted prototype parts from 3-axis to 5-axis. Same machines and tolerances as production runs.

Most popular

CNC Turned Prototypes

Round prototype parts -- shafts, bushings, and pins. Live tooling adds flats and cross-holes in one setup.

Round parts

Multi-Material Prototypes

Test different materials on the same design. Compare aluminum 6061 vs 7075, or Delrin vs PEEK, before committing.

Material testing

Functional Prototypes

Parts that work under load, pressure, or heat. Real material properties, not 3D printed approximations.

Real materials

First Article Runs

Bridge the gap between prototype and production. 5 to 50 pieces with full inspection and documentation.

Pre-production

Design Iteration Support

Fast turnaround on design changes. Send a revised STEP file and we re-quote within hours.
