Really a great experience. Recommended!

Great service, price, and turnaround time! We went through several rounds of prototype revisions and beat our deadline thank to your hard work and dedication.


Alan D. | Project Manager

Quality much better than expected!

I wasn't sure how good the quality would be after hearing people who had bad experiences manufacturing overseas. So I was pleasantly surprised when our parts arrived and were built exactly to spec and finished professionally, on par with anything in the US. Thanks!


Sara G. |  Industrial Designer

You saved my project!

After having two prototype shops screw up our parts, we were behind schedule and on track to be over budget. You guys came in and quickly delivered the quality we needed at a price that worked for us.

What Can We Help With?

A quality prototype is more than a useful sales and reference tool, it is also essential for determining the perfect function and threshold for a design.  Your CNC tooled, 3D-printed, or laser-cut prototype must be flawless the first time – especially before producing thousands of units or more.  At GS Proto, we offer a wide range of materials and options for producing your perfect prototype the first time, including metals, alloys, plastics, and rubbers. Not sure which materials you want or need to use?  Our designers are happy to offer their years of experience helping you determine a design, material, and prototype size matching your needs, and your budget.

Combining skilled designers and engineers, technological superiority, and integrated manufacturing processes to deliver low-volume manufacturing with speed, precision, and at the right cost.  When you need quantities of 50,000+ and you want them fast, GS Proto is your one-stop destination for tooling, casting, molding and more.  Get more manufacturer for your money.  When you choose GS Proto, you will have full access to:
