Industries / Transformers & Inductors
Industrial Electrical · Priority Sector

Specialized cutting for transformers and inductors.

Barrier insulation, inter-turn insulation, slot wedges, and winding tubes — cut in Nomex 410 and Hitex with tight tolerances to guarantee the integrity of every winding.

Sector Expertise

The number-one sector for Nomex and Hitex.

Transformer and inductor manufacturers are our benchmark market. This sector's requirements — tight tolerances, clean fray-free edges, guaranteed dielectric performance — match exactly what laser-cut Nomex 410 does best.

A poorly cut insulator can cause a short between turns, a continuity fault, or premature breakdown. That's why our transformer-sector clients keep coming back: every part is repeatable, measurable, and to spec. We deliver everything from engineering prototypes to full production runs.

Key Advantages

Why transformer manufacturers choose P&P.

Sealed, Fray-Free Edges

Laser cutting simultaneously seals the Nomex fibers. No conductive strand can come loose and migrate to neighboring turns — zero risk of edge-contamination shorts.

Part-to-Part Repeatability

Every part is cut by numerical control directly from your file. No operator-to-operator variation, no die wear — part 1 and part 1,000 are identical.

±0.1 mm Tolerances

Essential for slot wedges and barrier insulation where excess clearance compromises dielectric withstand voltage. Our tolerances meet IEC 60076 requirements.

No Tooling — Economical from Part 1

No die to order or store. Ideal for engineering prototypes, replacement runs, or custom windings in low quantities.
