Custom insulation parts for electric motors and winding.

Slot liners, slot closures, and phase insulation in Nomex — laser-cut with precision for coil winding shops and OEM industrial motor manufacturers. Sealed edges, guaranteed repeatability.

Sector Expertise

The partner for winding shops and OEM manufacturers.

Winding shops and electric motor manufacturers have two opposing needs: speed for emergency repairs, and repeatability for production runs. P&P Colorismédia meets both — prototypes in 48 h, production runs with the same quality.

The slot liner is the electric motor's critical part. Poorly cut, it can cause a dielectric breakdown on the very first start-up under load. Our Nomex 410 laser cutting guarantees clean edges, accurate angles, and uniform thickness — regardless of the complexity of the slot profile.

Key Advantages

Why winding shops choose P&P.

Complex Slot Profiles

Every manufacturer has its own slot geometry. We cut any profile — open, semi-closed, rounded — directly from your DXF, with no tooling cost.

Fray-Free Nomex

The laser beam seals the aramid fibers as it cuts. No strand can migrate into the winding during insertion or under vibration — UL 94V-0 compliance maintained.

Repair-Friendly Lead Times

A motor down costs money. We deliver replacement batches in 48 business hours for emergencies — even in low quantities.

NMN Laminates Available

Nomex/Mylar®/Nomex — the reference laminate for phase insulation, combining the mechanical strength and superior dielectric properties of both materials.
