Q. Hello!
Could I have advice on the following?
* System: gasoline injector

- Important, the four corners are rounded by final diametral length of 4.82 ± 0.005 ( diagonally) which shall fit to the outside bore with interference; coating purpose is to minimise the metal to metal stick slip on those corners when assembling.
* Operating conditions:
- Media Fuel E100, M30 contact (Temp: -40~110 °C)
- General tolerance max. 7 ??
- Injector as assembled
* Op. temp: Max. 150 °C

- Business
* Amount 100K to 300K per year
Any advice on the coating solution and pricing is appreciated in advance.
