01
What we need from you
- Failed samples and the failure history
- Drawing if one exists
- Operating conditions: load, speed, lubrication, environment
- Assembly details and mating parts
Solution
If it keeps failing, it is telling you something
Replacing the same part every few months is not maintenance — it is an unfixed engineering problem with a recurring invoice attached.
- Failure mode identified from samples
- Interfaces preserved
- Improvement proved in service
Best for
Parts that fail repeatedly or never quite fit
You send
Failed samples, failure history and operating conditions
You get back
A revised drawing and an improved part, trialled
How it starts
Assessment of the likely cause before any manufacture
The situation
The recurring replacement
The part is cheap. The downtime, the labour and the consequential damage are not — and they recur on the same cycle.
- 01The same component replaced again and again
- 02Premature wear, seizure or fatigue cracking
- 03Fits that need hand work at every assembly
- 04Finish problems on sealing or sliding surfaces
What you get
What working with CMTA actually delivers
Diagnose recurring wear, failure or fit problems and engineer the fix.
A named failure mode
The cause identified from the failed samples, the history and the operating conditions — rather than a replacement made to the same flawed drawing.
Options with trade-offs
Material, hardness, geometry, finish or fit changes proposed with what each one costs and buys.
Interfaces preserved
Mating dimensions are held unless a change is agreed with you, so the improved part still fits the machine.
Proof in service
Service life or performance compared against the original, with results recorded.
Where this stops
Sometimes the component is fine and the real cause is lubrication, alignment or loading. Where the evidence points there, we will tell you rather than sell you a better version of a part that was never the problem.
02
Acceptance
Service life or performance in trial against the original component, recorded so the improvement is evidenced rather than assumed.
How it runs
The route from enquiry to verified result
Each stage produces something you can check, and the drawing approval stage is yours to control.
- 01
Diagnose
Failure mode identified from samples, history and operating conditions.
- 02
Propose
Improvement options with trade-offs, issued as a revised drawing for approval.
- 03
Manufacture
Improved part made to the approved revision.
- 04
Trial
Run in service against the original, with the result recorded.
Before you enquire
What to send, and where to look next
The inputs that make a useful review, plus the related pages worth reading first.
Does this sound familiar?
- Same part replaced repeatedly
- Premature wear or seizure
- Fits that need hand work at assembly
- Surface finish problems on sealing or sliding surfaces
If two or more apply, this is probably the right route for you.
FAQ
Frequently asked questions
The questions engineers and buyers ask before sending a drawing. If yours is not here, ask it directly — you will get an engineer's answer, not a brochure.
Still have a question?
Talk to Anita M.N, Managing Partner, or send the drawing and let the review answer it.
Can you tell why a part keeps failing?
Usually, from the failed samples, the history and the operating conditions. The assessment states the likely cause and the improvement proposed.
Will an improved part still fit the machine?
Yes. Interfaces are preserved unless a change is explicitly agreed with you.
Can you improve a part you did not originally make?
Yes, through the reverse-engineering route with improvements built into the new drawing.
What if the component is not actually the problem?
Then we say so. Lubrication, alignment and loading cause failures that no amount of component redesign will fix.
