Flexible electrical resistors

Flexible heating elements are the ideal solution when small nozzles need to be heated or when the specific power or working temperature reaches high values. Flexible tubular electric heating elements with stainless steel braid, square or "D" shaped, are mainly used in hot blocks (hot runner systems) for moulds.

They come in various sizes and can be bent to fit into almost any 2D or 3D channel. The outer mantle (braid), made of pure nickel, adapts to any curvature and applies uniform pressure to the channel surface, ensuring optimal heat transfer even under extreme mechanical stress.

With these resistors, specific powers of up to 8 W/cm² and working temperatures of up to 600°C can be achieved.
