Bosch a world known organization was seeking a solution for quality check for one of their component. This time it was a nozal where Single miss out on hole count raises an alarm on reputation of the company and this task been very complex, it was impossible to manually inspect 100% nozzles manufactured. Hence, Acme was invited to propose a solution.
  • Purpose: To detect the number of holes for different types of nozzles
  • Problem: The size of a hole varies from 100 microns to few milli meters, which makes it difficult to detect through naked eye.
  • Procedure: Implement an automated vision based inspection system


  • Nozzles are used for fuel injection in engines.
  • Based on applications, each engine requires specific number of holes for injecting fuel.
  • Detecting minute size of holes through human vision is error prone and time consuming.
  • Hole size and number of holes varies with nozzle types

Our solution

  • Implemented a vision based inspection system that:
  • Counts the number of holes in a nozzle irrespective of  the hole size and nozzle type.
  • notifies the user with the hole count.

  • Takes 1.2 sec to 4-sec for inspection of a single nozzle.


  • Vision based inspection system to detect the number of holes for different types of nozzles.
  • Notification of hole count to user by digital dashboard.
  • Almost 100% accuracy
  • Increase in overall productivity
  • Additional software to verify the hole count visually.
  • Quality assurance, 24*7 technical support
