Designed To Fit Your Application

The size and shape of your custom flexible heater will be determined by your final application. Standard shapes are square, rectangular, or round but any shape desired can be custom designed and produced to meet your electrical and thermal performance requirements. Most size, shape or contour can be used to apply direct and efficient heat without decreasing reliability.

Flexible Heater with Custom Designed Shape

We utilize state of the art capabilities such as laser cutting of outlines, allow us to offer endless shape configurations with tight dimensional tolerances with all our flexible heater products.

Variety Of Geometries

Flexible heaters can be manufactured in a variety of geometries to fit specific heating requirements.


Most common geometries of flexible heaters include:

  • Rectangular or square-shaped heaters
  • Circular heaters
  • Triangular or diamond-shaped heaters
  • Thin, narrow, or long heaters
  • Custom-shaped heaters designed to fit specific equipment or machinery.
  • Multi-zone heaters with different temperature zones across the surface of the heater. Multizone flexible heaters are a type of heating system that is designed to be adaptable and customizable. These heaters consist of multiple heating zones that can be independently controlled, allowing users to adjust the temperature in different areas of the heater as needed.
  • Heaters with cutouts for sensors, cables, or other components. Several types of sensors can be used with flexible heaters, depending on the specific application requirements. The type of sensor used with a flexible heater will depend on the specific temperature range, accuracy, and response time requirements of the application.
  • Holes can be placed in flexible heaters for a variety of reasons, such as to accommodate mounting points, sensors, or other components. These holes can be created using methods such as punching, drilling, or laser cutting.

The choice of geometry will depend on the heating application, available space, and other factors such as the desired wattage density, temperature range, and operating conditions.
