Design Basis
  • Design by Power Suitable for applications with fixed voltage and desired total power. Common in thermal control scenarios.
  • Design by Resistance Ideal for circuits requiring specific resistance values. Offers precise control over heating element behavior.
  • Design by Temperature For use cases targeting a specific working temperature. Requires material and environmental considerations.

Superb Apperance Quality

Select this option to enable 100% visual inspection with strict appearance standards. Even minor defects like wrinkles, light scratches, or misalignments will be rejected and re-manufactured to ensure perfect appearance in every piece.

  • Yes
100% Resistance Testing

Select this option for 100% resistance testing of all flexible heaters in your batch. Each piece will be individually measured to ensure consistency with your design specification
