Our Injection Molding Process
Tell Us What You Need
Send over your drawings, CAD files, or a prototype concept. Our team reviews the details and returns a clear quote covering both tooling and production.
Design Review
We assess how well your part will mold and recommend adjustments that improve durability, performance, and cost before anything gets built.
Sample Production
We build your mold and run first-article samples (T-1). Once you sign off, we handle finishing steps like texturing or polishing.
Full Production
After your mold is validated and prepped, we run it in our facility, complete a final inspection, and ship finished parts straight to your San Jose location.
