The Packaging Line Spares Problem
Packaging machinery has two chronic parts problems. First, wear parts — cams, jaws, guides — that the OEM supplies slowly and expensively, treating spares as a profit centre. Second, change parts: when you switch to a new bottle or carton format, the OEM may no longer support your machine's generation, quoting months or declining entirely.
Both are machining problems, and both are solvable: we reproduce wear parts from your worn originals and design new change part sets from your machine's interface geometry plus the new container.
Parts We Make for Packaging Machines
Cam plates & tracks
Motion profiles measured and reproduced; hardened where the original wore.
Star wheels
Container-handling profiles in food-contact acetal, sized to your bottle.
Timing screws
Infeed worms machined to your container diameter and pitch.
Sealing jaws
FFS jaw sets in tool steel or aluminium-bronze, serrations reproduced.
Forming tubes & shoulders
VFFS film path geometry reproduced, product-contact polished.
Guide rails & wear strips
UHMW-PE and stainless rails to your line profile.
Filling nozzles
316L product-contact nozzles and valve components.
Capping chuck parts
Chuck inserts and clutch components sized to your closure.
Change Parts for New Container Formats
A format change shouldn't require OEM permission. To design a change part set we need:
- One existing change part set — gives us the machine interface: mounting pattern, pitch circle, drive engagement
- The new container — physical samples preferred; accurate drawings acceptable
- Line speed — affects pocket clearance and lead-in geometry
We machine the set — star wheels, guides, timing screw — with the same interface as your existing sets, so changeover procedure stays identical.
Food-contact compliance. Product-contact components are machined in food-contact certified acetal, UHMW-PE or 316L stainless with surface finishes appropriate for washdown. Tell us your product (dry, liquid, acidic) and washdown regime, and we specify materials accordingly.
How It Works
- Send the worn part or change part set — plus container samples for format work
- Free CAD reconstruction — confirmed before machining. See machine parts RE
- Order duplicate sets — second sets from the same CAD at significantly lower cost

Held Hostage by a Change Part
This page is about breaking a double grip — the OEM's price for a simple change part, and the lead time when one wears out mid-campaign. We machine the star wheel, infeed screw or cam plate to your container instead of the badge, and quote it in days. Here is who reaches us, and what they're up against.
"We're launching a new bottle format and the OEM won't quote change parts for a filler this old"
Send a change part from the current format plus the new container — or just its dimensions. We design the new star wheels, guides and timing screw around it, keep the machine interface identical, and change only the product-contact profile. The line runs the new SKU without a new machine.
"The cam track is worn, the machine's out of warranty, and the OEM quotes months for a plate"
We measure the motion profile off your worn cam and reproduce it — hardened where the original gave out, so it lasts longer this time round. Send the part during a planned stop and we quote the day it lands; a spare in the same run means the next wear-out isn't a crisis.
"We run dozens of SKUs and need change-part sets for formats the OEM stopped supporting"
Routine work here: star wheels, infeed worms and guides sized to each container in food-contact acetal and 316L, reproducible from saved CAD as the format list grows. One quote covers a mixed set, and a reorder for a repeat run is a single email rather than a fresh project.
"A simple machined change part shouldn't cost what the OEM charges — I want a real second source"
You're paying for the badge, not the machining. We cut the same star wheels, jaws, nozzles and chuck parts to fit, with mill certs and food-contact materials where the line needs them, at a fraction of list — direct from the shop, CAD kept so the price drops again on the reorder.
"I recondition used packaging machines to resell, but they arrive with change parts missing"
We fill the gaps so a refurbished line ships complete: missing star wheels, guides and chuck parts remade from the surviving set or the container spec. One quote for the whole shortfall list, and the CAD stays on file so the next machine of the same model is a fast reorder, not a fresh measure-up.
What Buyers Search For When a Packaging Part Fails
Frequently Asked Questions
Usually yes, significantly. Change parts — star wheels, guide rails, timing screws sized to your container — are machined components without complex tooling. We reproduce them from your existing set or design them from your container dimensions, typically at a fraction of OEM list price.
Yes. Send us an existing change part set (for reference geometry) plus the new container — or its dimensions — and we design and machine the new set: star wheels, guides, timing screw. The machine interface stays identical; only the product-contact profile changes.
Yes. Forming tubes and shoulders are precision components with polished product-contact surfaces. We reproduce them from your existing tube including the film path geometry. 304/316 stainless, polished where film and product touch.
Yes. Sealing jaws are commonly reproduced in tool steel with hardened serrations, or in aluminium-bronze for heat conduction with better wear. Tell us the film type and seal temperature and we specify the right material and hardness.
For change parts the container is often enough. Send the bottle, jar or pouch — or a dimensioned drawing of it — plus a photo of how the part mounts, and we design star wheels, screws and guides around it. An existing change part helps us copy the machine interface exactly, but it isn't always essential.
Yes. We quote and machine the complete set — star wheel, timing screw, guide rails, any chuck or jaw parts — as a single job, so everything is dimensioned to the same container and arrives together. The CAD for each format stays on file, so adding the next SKU later is faster and cheaper.
