How Our Mica Commutators Are Processed/Made

The journey of creating Axim Mica’s esteemed mica commutators is rooted in a meticulous process:

  • Mica Selection

    We start with premium-grade mica, known for its exceptional electrical insulation and thermal properties.

  • Grinding into Fine Powder

    The selected mica is then ground into a fine powder, providing the base material for the commutator.

  • Forming Layers

    This mica powder is layered, under pressure, with a resin binder to form sheets that will become the commutator segments.

  • Cutting and Shaping

    These mica-resin sheets are precisely cut and shaped into the commutator segments.

  • Assembly

    The segments are expertly assembled, with insulating properties between each, onto a shaft, forming the final commutator ready for installation.
