Prototyping
From CAD to a part in your hands. Functional prototypes, jigs, and fixtures — built to spec and iterated fast.
POC → Low-volume manufacturing
A proof-of-concept isn't a product.
We make it one.
Gelco turns a working POC into dependable low-volume production — through fast prototyping, a costed and version-controlled BOM, and a supply chain we organise end to end. The agility of a small team, the rigor of an experienced one.
01 — What we do
End-to-end, not just fabrication.
Four capabilities that carry a design from a part in your hand to a run out the door. Pick the ones you need, or hand us the whole bridge.
Low-volume production
Repeatable runs from a handful to a few hundred units — consistent quality without tooling up for mass production.
BOM management
A bill of materials you can trust — costed, version-controlled, and ready for procurement at any scale.
Supply-chain management
Sourcing, vendor vetting, and logistics handled end to end — so your bench time goes into the product.
02 — Why Gelco
Most proofs-of-concept die in the gap between "it works on the bench" and "we can build a hundred of these."
That gap is our entire focus. We've spent 10+ years on both sides of it — inside multinationals where process is everything, and inside startups where speed decides survival.
Gelco brings both: the discipline of an established manufacturer, delivered by a small team that actually answers the phone. Our production floor scales with you — from a 2 m² bench for early builds to 300 m² for a full low-volume run. The same people see it through, from first prototype to final shipment.

03 — Process
Concept to delivered product, in four moves.
A clear path with no hand-offs to strangers. You see the same faces at every stage.
-
01
Prototype
We turn your concept or POC into functional, testable parts — fast iterations in real materials.
-
02
Refine
We harden the design for manufacture: tolerances, materials, cost, and assembly all dialled in.
-
03
Source & manage BOM
We cost the bill of materials, vet vendors, and lock a supply chain you can rely on.
-
04
Produce & deliver
We run your low-volume production with consistent QC and ship finished, inspected units.
04 — In their words
"Working with Gelco felt like adding a senior manufacturing team overnight — without the overhead. They sweat the details we couldn't get to."
Tamas Babel
Founder · Ongo Vision
"Gelco understands the many constraints in prototyping — and beyond. They bring a manufacturer's eye to the prototype stage, so what we build is already something that can be made."
