One Custom Parts Maker, Any Material
Most suppliers do one process and demand a finished CAD file. EKINSUN is built differently: we're a custom parts manufacturer that picks the right process — CNC machining, injection molding or casting — and the right material for your part, and we'll engineer it from whatever you have. Need one piece, a replacement for a discontinued part, or a small batch? That's exactly our lane. As a precision machining company we hold tight tolerances and gauge-verify every part, but without the finished-CAD requirement most shops insist on.
Real Custom Machined Parts We've Made
Not stock photos — actual customer jobs, each machined from a hand sketch and gauge-verified before it shipped. This is what "custom machined parts, no CAD" looks like in practice:
Mixed-thread stud & coupler
UNF + UN + metric on two parts, gauge-verified →
Double-male M30×3.5 → M24×2 stud
Sketch → full production drawing → part →
Male-female M30→M24 adapter
A pencil sketch, turned into a real part →

Everything a custom machined part needs, verified before it ships. Our precision machining services cover turning, milling, 3/4/5-axis and EDM under one roof — if your drawing calls out something not listed here, ask; this is a summary, not a limit.
| Processes | CNC turning, milling, 3/4/5-axis, EDM, plus vacuum casting & molding for plastic batches |
| Tolerance | ISO 2768-f general; critical features to ±0.01 mm where specified |
| Materials | Aluminium, steel, stainless (304/316), brass, titanium · Delrin/POM, nylon, PC, PEEK, PTFE |
| Part size | Ø1–500 mm turned · up to 800 mm milled envelope |
| Quantity | 1 piece to small-batch production — no setup fee on machined one-offs |
| Threads | Metric, UNC/UNF/UN, BSP/BSW and non-standard pitches, single-point cut & gauge-verified |
| Verification | Thread ring/plug gauge, micrometer & caliper, CMM report on request |
| Certification | ISO 9001:2015 (ISO 13485 for medical parts) |

Custom Parts We Make
Every part below has its own page with specs, materials and how to order — many can be reproduced from a sample with no drawing. Can't buy the part anymore? See replacement parts for machines, pumps and equipment. Keeping a machine running? See replacement machine parts. Need a door part? See custom door hardware. Looking for custom fasteners or adapters & fittings? We make those too.
Gears, Drives & Rotating Parts
Housings, Bodies & Fluid Parts
Brackets, Mounting & Hardware
Thermal, Enclosures & Electronics
Don't see your part? We make far more than we can list — tell us what you need and we'll quote it.
CNC Machining From Drawing — Already Have a Sketch or Spec?
If you already have a drawing, DXF, sketch or specification, we go straight to quoting and machining — no back-and-forth needed. CNC machining from drawing is the fastest route: send the file (or a photo of a hand sketch with dimensions) and receive a price and lead time within 24 hours.
We machine parts from your drawing in any material — aluminium, steel, stainless, brass, PEEK, Delrin — to the tolerances and surface finish it calls out. That covers bespoke, non-catalogue components for UK and European customers, and it works the same whether you send a full SolidWorks export or a ruler-annotated photo of a rough sketch: we confirm the geometry with you before any metal is cut.
Accepted drawing formats: STEP, IGES, DXF, DWG, PDF drawing, dimensioned photo, hand sketch scan. If you're unsure whether your file is usable — send it and we'll confirm within the hour.
No CAD? Order From What You Have
You don't need engineering software to get a custom part. Pick whichever matches what you're holding — our engineers turn it into a confirmed CAD drawing for free:
A photo
Clear photos of an existing part + one reference dimension. From a photo →
A hand sketch
A rough drawing with the sizes you know. Sketch to part →
A physical sample
Mail us the part to copy — even worn or broken. Parts from a sample →
Just measurements
Key dimensions and what it does. Order with no CAD →
Discontinued or obsolete part? If you can't buy it anymore, we reproduce it from the old one — see obsolete & discontinued parts, how we reverse engineer them, or get a discontinued plastic part remade.
EKINSUN vs. an Instant-Quote Platform
Upload-a-CAD-file platforms are fast when you already have a finished model and a standard part. For a one-off, an odd part, or something you can only photograph, they're the wrong tool — here's the difference:
| Instant-quote platform | EKINSUN | |
|---|---|---|
| To get a price | CAD file required | Drawing, sketch, photo or sample |
| One-off / odd part | Auto-quoted, no human check | A real engineer reviews it |
| Obsolete part copy | Not supported | Reverse-engineered from the old one |
| You talk to | A web portal | The people cutting the metal |
| Minimum order | Often a batch minimum | 1 piece, no setup fee |
Frequently Asked Questions
One that makes parts to your specific requirement, not off-the-shelf items. EKINSUN custom-makes parts in metal, plastic and silicone by machining, molding and casting — one-offs, discontinued-part replacements and small batches, from a single piece.
Yes — our specialty. Send a photo, a hand sketch with dimensions, or a physical sample; our engineers create the CAD for free, confirm it, then make the part. No CAD software needed.
Metal (aluminium, steel, stainless, brass, titanium…), engineering plastics (Delrin, nylon, PC, PEEK, PTFE…), and silicone or rubber. We choose the material and process to suit your part, quantity and budget.
One piece, with no setup fee on machined parts — a single custom part or prototype is welcome, and we also run small to medium batches.
Instant-quote platforms need a finished CAD file just to price a part, and the quote is automated with no human check. We work from a drawing, sketch, photo or physical sample, and a real engineer reviews every part — which suits one-off, odd or obsolete parts that don't fit an automated portal.
Typically ISO 2768-f general tolerance, with critical features to ±0.01 mm where the drawing calls for it. Threads are checked with ring and plug gauges, diameters with micrometers, and full CMM inspection is available on request.
Yes. Our precision machining services cover CNC turning, milling, 3/4/5-axis and EDM, working to ISO 2768-f general tolerance and down to ±0.01 mm on critical features. Unlike most precision machining companies we don't require a finished CAD file — a drawing, sketch, photo or sample is enough — and there's no setup fee on one-off machined parts.
