Wire Wound Silicone Rubber Heaters


A fine nickel-chromium alloy wire is spiraled onto a center core of fiberglass, producing a strong, flexible heating element. Electronically-controlled precision winding equipment ensures consistency. Circuits are then hand-wound on permanent tooling, providing repeatability of resistance and pattern. Parallel circuits are utilized where possible, permitting continued operation should a single circuit be damaged.

Wire wound advantages over etched foil element:

  • Faster turnaround time on prototype designs
  • Lower engineering cost
  • More economical pricing at lower quantities
