PROTOTYPEYour CAD file. A real part.
48 hours.
Injection-molded caps, overmolded grips, and living hinges that snap with the right resistance — on the very first sample. We speak GD&T before we speak deadline.
"A Fortune 500 oral care brand needed 200 shelf-test units in eleven days."
From DFM red-line to retail shelf in 11 days.
Their incumbent molder quoted 14 weeks. We received a STEP file for a child-resistant pump cap on a Monday morning. DFM analysis flagged three undercuts and a gate location that would have caused sink marks on the visible face. We moved the gate, added 0.5° draft to the snap-fit arms, and had first articles in their hands by day 5.
200 units. 11 days. Zero rejections at shelf audit.
"They flagged a draft issue our internal tooling team missed. First articles arrived before our planogram meeting."
"A Series A startup needed ten overmolded ergonomic handles for a Target buyer meeting — next Thursday."
Ten two-shot handles. One week. One buyer meeting that closed.
The product was a kitchen tool with a PP substrate and TPE overmold grip. The founder needed the parts to feel production-intent — not like prototypes. We ran tool-path simulation overnight, identified a knit-line that would have appeared on the grip texture, and shifted the overmold gate 8mm. The buyer picked up the part and asked which factory made it.
Buyer mistook the prototype for production. Deal closed.
"The Target buyer held the handle and asked which factory we were using for production. That was the moment."
"A packaging engineer at a CPG company needed to iterate on a living hinge that was sealing inconsistently — tolerances deciding whether a lid leaked or locked."
Four tolerance iterations. Third one sealed. No leaks in accelerated testing.
Living hinges are unforgiving. The hinge geometry was 0.3mm thick PP with a 15mm flex radius. Their current supplier was shipping parts with flash at the hinge root, causing stress concentrations that failed at 1,200 flex cycles instead of the required 10,000. We rebuilt the hinge cross-section, adjusted fill speed, and ran four first-article iterations. The fourth sealed consistently at 0.02 bar positive pressure.
12,400 flex cycles. Zero failures. Seal holds at 0.02 bar.
"Four iterations in three weeks. Our incumbent supplier took four months and never solved the flash issue."
