Five Casting Processes. One Roof. Zero Compromises.
We don’t force your design into a single process – with five casting disciplines, in‑house patternmaking, 16 CNC machines, and full finishing under one roof, we choose the optimal method for your part and deliver it turnkey.
General Foundry takes you to the next level — we match your design to the best process, not the other way around.
With five casting processes under one roof (Green Sand, No‑Bake, Permanent Mold, Rubber Plaster Mold, Investment Casting) – plus 3D‑printed sand molds for prototyping – our engineers evaluate your design and select the optimal process for geometry, tolerance, finish, alloy, and volume. One facility. One contact. One standard of quality.
From thin-to-thick wall transitions and complex internal geometries to cosmetic housings and load-bearing structures, we align design intent with process capability early to achieve first-time-right results.

Our True Turnkey Casting Capabilities Include
Castings so refined they’re mistaken for machined billet
Our Class A medical and cosmetic finishes – precision machining, powder coating, plating, and polishing – meet the strict cosmetic and functional standards of medical, biotech, and precision instrumentation.
Full-Service Casting, Machining, and Prototyping – From Pattern to Finished Part
In our 65,000 sq. ft. San Leandro facility we control every stage – design validation through final inspection – reducing lead times, lowering risk, and delivering production‑ready parts.
What this eliminates for you:
- No trucking parts between separate providers
- No finger‑pointing when issues arise at machining
- No coordination delays across vendors
- No unexpected machining costs from poorly matched casting choices
- One contact, one quality standard, one facility
Industries Served
From surgical robots to defense systems – our castings perform where it matters most.
What Our Clients Say
Trusted by top engineering teams across the country for speed, precision, and quality.
"I have worked with several different vendors, guys but I've honestly never- ever-ever gotten to a clean FAI this quickly. Thanks for the hard work."
"Once again, I very much appreciate and value your attention to little details. The bases are beautiful, and solid as a rock. This device is really coming together, and your castings are playing a huge part in the overall success."
"Again, great follow up, thanks for the tracking; General Foundry's quality of work is great, even our inspection team said wow (and that's rare) so great job."
