We machine parts from solid billet for prototypes, short-run production and fixtures. Precision CNC machining sits inside our rapid prototyping work, so a part can be milled or turned to prove a design and then carried through to a moulded production part in the same building. We cut engineering plastics and ferrous and non-ferrous metals.
The Process
CNC machining removes material from a solid block or bar to reach a finished part, working to the geometry in your CAD model. It is a direct route to a functional part in the real material, which makes rapid CNC prototyping a natural first step before a mould is cut. The same file that drives a prototype machining job can go on to inform the production tool. Because billet machining works from solid stock, there is no tooling to commit before you have a part in hand.
Our tool room mills and turns in house, backed by EDM, wire erosion and grinding for tighter detail. That plant exists to cut moulds, so a CNC prototype, a jig or a fixture is machined by the same people who build production tooling, on the same equipment.
Because moulding sits under the same roof, a one-off or short-run machined part can feed straight into tooling and production moulding without changing supplier or re-quoting from scratch.

Where CNC Fits
Where a prototype needs a real engineering material and closer tolerances, Gemini machines complex one-off or multiple prototypes straight from CAD in our own tool room, no tooling required, in a range of plastics or metals. It gives you a part in a production-representative material.
A CNC prototype in the production material, for fit, form and function testing before a tool is committed.
Machined parts where the numbers do not justify a mould, or a one-off is needed alongside a moulded product.
Assembly jigs, checking fixtures and tooling components machined to support a wider moulding or build programme.
Inside Gemini
From a drawing to a finished part, you deal with one accountable UK tool room. Here is how it works.
Send a STEP, IGES or 2D drawing, or just a sketch and the material you have in mind.
We check machinability, suggest the right plastic or metal, and come back within one business day.
Cut from billet in our own tool room, in a production-representative material, ready for fit and function.
