Automotive Prototyping: Fuel, Heat & Tolerance
Automotive testing is about heat, chemicals and vibration together — which narrows the material list fast.

Send a drawing and a target quantity. We will come back with material, process and a realistic date, or tell you what we would change first.

What actually goes wrong in automotive & mobility
These are the three problems that decide whether a automotive & mobility prototype succeeds or gets scrapped on arrival.
Heat and chemical exposure
Underhood and in-cabin parts see heat, oils, fuels and cleaners. A part that survives a bench test can fail a chemical soak, and the material has to be chosen for the worst exposure, not the average.
Vibration and fatigue
A prototype that is only static-loaded will not tell you about fatigue. We will advise whether the quantity and material you have chosen can produce a meaningful fatigue result, or whether a larger test programme is needed.
Quantity versus question
Ten parts answer a fit question. A hundred answer a fatigue question. The prototype plan has to match the question being asked, which is often the most expensive thing to get wrong.
Our approach on automotive & mobility parts
- 01 We ask what the prototype has to prove before recommending quantity, material and process.
- 02 Where the test plan needs a specific number of cycles, we say whether the material and process can support it.
- 03 We flag a prototype that will give a false result — that conversation is cheaper than a failed test programme.

A prototype answers geometry and fit. It does not qualify a product, and we will not pretend otherwise. These are the questions that need a test programme.
