A snapped shaft, a cracked housing, a stripped gear — and no replacement to buy. Send us the pieces. We reconstruct the geometry from the fragments and machine a new part, often stronger where the old one failed.
Searching for help with a broken machine component mostly turns up machine-tool rebuilders and repair shops — useful if you want the whole machine overhauled, useless if what you actually need is one new part to replace the one in pieces on the bench. That single-part problem is what this service answers.
The good news: a broken part is still an excellent manufacturing reference. The fragments carry the bores, threads, profiles and mounting faces almost untouched, and the fracture itself tells us where the part was weakest. We measure the pieces, reassemble them digitally, reconstruct whatever material the break destroyed, and machine a new part — to the original geometry, or with the weak point fixed.
Fatigue at the keyway or shoulder — the classic. Re-machined with proper radii, alloy upgrades available.
Tooth profile recovered from undamaged teeth; harder material or surface treatment where wear was the cause.
Cast housings reproduced as machined billet — stronger and porosity-free.
Bent or snapped levers and mounts, reconstructed to true geometry, not the deformed state.
Including non-standard threads and shoulders. See custom fasteners.
Machined or vacuum cast in engineering polymers — no original tooling needed.
Why did it break? Reproducing the part exactly is sometimes the wrong answer — if a sharp internal corner started the crack, the same corner will start the next one. When the fracture shows a design weakness we say so, and quote the reinforced version alongside the exact copy. Same fits, same function, more metal where it matters.
| Route | Makes sense when | Limits |
|---|---|---|
| Weld repair | Large part, simple break, low precision | Distortion, altered metallurgy; precision fits rarely survive |
| Sleeve / bush the damage | Local wear on an otherwise good part | One-time fix; underlying part keeps aging |
| Reproduce new (us) | Precision part, repeat failure, or no spare exists | Lead time in days–weeks; one-off costs more than batch |
If the part isn't broken yet — just unavailable — see discontinued parts made to order. And if the maker of the machine no longer exists at all, start at manufacturer out of business.
Broken and damaged parts sent to EKINSUN — reproduced from fragments, worn pieces and partial samples:
The idea behind this page is counter-intuitive — the fragments in your hand carry almost all the geometry, and the fracture itself tells us why the part failed, so a broken original is a better starting point than no original at all. Nobody plans to ship a part in pieces, but the people who do have usually had the same morning. Here is who they are.
Photograph the pieces against a ruler and send them — we quote within 24 hours and flag it as a breakdown, so the CAD reconstruction and machining jump the queue. Simple turned or milled parts can ship in days, and we'll cut a spare from the same setup so the next 2am call isn't a crisis.
Then the fracture is the useful bit. A fatigue beach-mark off a sharp corner, an overload shear — we read where it started and quote a reinforced version beside the exact copy: a radius where the crack began, billet instead of casting, alloy or heat-treat where plain steel gave up. Same fit, more margin.
A broken original is still an excellent pattern — the fragments hold the bores, threads and faces almost untouched. We reassemble them digitally, rebuild what the break destroyed, show you the reconstructed dimensions for sign-off, and machine a single new part. No drawing, no OEM, MOQ 1.
That is the whole job here. Send the pieces — unrepaired, all of them — and we reconstruct and remanufacture to fit, keep the CAD for the next identical failure, and quote batches when you want shelf stock. You give your customer a fix instead of a shrug.
Usually yes. Fragments carry nearly all the geometry — fits, threads, profiles — and the fracture faces tell us how it failed. We reassemble the pieces digitally, reconstruct any material lost at the break, and flag reconstructed dimensions on the drawing for your approval before machining.
Often, and we'll recommend it when the break shows a design weakness: a sharp internal corner that started the fatigue crack gets a radius, a cast part becomes machined billet, a plain steel becomes alloy or heat-treated. Same fit and function, more margin at the failure point.
Tell us it's a breakdown when you send photos — we prioritize the quote and the CAD reconstruction, and quote express machining plus courier shipping. Simple turned or milled parts can ship in days. Photos of the pieces with one known dimension are enough to start; the quote comes within 24 hours.
Don't — for measurement, loose pieces are better than a repaired part with weld distortion or glue gaps. Send the fragments as they are, and keep all of them if you can; even small chips from the fracture zone help us reconstruct the original geometry.
Often, yes. Missing pieces from a symmetrical or repeating feature — a gear tooth, a bolt circle — can be reconstructed from the parts that survive. Send everything you have plus photos of the assembly it came from, and we'll tell you honestly at quote stage whether what's left is enough or whether we need one known dimension from the mating part.
Yes. We produce a dimensioned CAD model and drawing from the fragments and send it for your approval before any metal is cut, with reconstructed dimensions clearly flagged. You keep the drawing and we keep the CAD on file — so if it ever breaks again, the replacement is a quick reorder, not another reconstruction.
Photos of the pieces are enough. Reply in 24h.
