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.
Custom Parts by Material
Custom Metal Parts
Aluminium, steel, stainless, brass, titanium and more — CNC turned and milled to tight tolerance, with finishing.
6061 →304 →All metals →Custom Plastic Parts
Engineering plastics — Delrin, nylon, PC, PEEK, PTFE — CNC machined, or molded/cast for batches without steel tooling.
Vacuum casting →Injection molding →Custom Silicone & Rubber
Silicone and rubber-like parts by molding and casting — seals, masks, soft components and low-volume copies.
Silicone molding →Medical silicone →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:
Gears, Drives & Rotating Parts
Housings, Bodies & Fluid Parts
Brackets, Mounting & Hardware
Don't see your part? We make far more than we can list — tell us what you need and we'll quote it.
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. Reverse engineering →
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 how we reverse engineer discontinued parts, or get a discontinued plastic part remade.
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.
