Michelin to improve quality control with a microscopic view

Michelin’s customer service department carries out inspections and controls in the tire production sites to provide feedback internally to other Michelin sites and externally to the subcontractors of molds and metal parts and guide them in their technical choices.

To efficiently perform these inspections, the team needs microscopes that are:

  • Robust, compact, and with a long product life cycle
  • Able to clearly show and highlight any defect, ideally with a polarizing camera to avoid reverberation or adding light
  • High image quality with a wide range of magnification to allow precise diagnosis
  • Easy to use and connected to a smartphone with a remote collaboration solution to accelerate decision making

Use case: Quality control of the cleaning tools that allow the production of tires

The Dino-Lite microscope is used to investigate the quality of the cleaning. By magnifying, and thanks to the
excellent image quality, it is possible to see if there is still some dirt residue left. By connecting the microscope
to a smartphone, this information can be shared live through XpertEye.


Quick analysis in the field with to-the-point decision making

Use case: Quality control of laser marking

Michelin uses laser engravings on its molds. To the naked eye, only a black aspect can be seen on the mold,
but when taking a closer look with a Dino-Lite microscope, the texture made by the laser can be distinguished
and their cleanliness can be evaluated. The microscope shows for instance that there has been a deposit of dirt
inside the texture which obstructs it and hence impacts the quality of the mold. These analyses are very easy
and quick to perform and reveal very precise information.


Produce a good tire on the first try

Use case: Inspection of the tire envelope

The Dino-Lite microscope is used to provide customers with a more accurate inspection of the tire envelope.
During an XpertEye call, pictures can be shared to show the origin of a defect such as the type of breakage of
a wire rope. In addition, the microscope manages the polarization of the image on metallic surfaces which are
often shiny and reflective. This allows for sharing a very precise image, especially of the end of the cable, which
is not possible with the camera of a smartphone.


  • Timesaving: faster decision making
  • More accurate feedback to tire developers
  • Reduction of customer travel
