Heating elements


Ceramic heating elements made of silicon nitride can be produced in various sizes and shapes and adjusted to fit the dimensions of the goods to be packed. Typical shapes are ring heaters, rectangles and heated rails. The good thermal conduction and the low thermal mass of the ceramic material allow extremely fast heating rates, a uniform temperature distribution and high control accuracy. The high strength of hot-pressed silicon nitride guarantees high stress resistance and excellent wear resistance at short processing times. The ceramic material is resistant to disinfectants and detergents and does not react to food in any way. We provide heating elements for packaging machines for operating in the open air at temperatures up to 500 °C. Performance and temperature control can be adjusted to the material and the packaging machine.

Customized design

Our in-house designs make any modification in size, configuration or electrical power simple and convenient. Mounting-bracket holes and bores for temperature sensors can be included. Processing our heating elements we can achieve a flatness and a dimensional tolerance of < 10 μm. Mounting-brackets and machine connections can be built and included in the delivery of heated rails. In addition various contours adjusted to the shape of materials or tools to be heated are possible. For cutting processes it is possible to grind a cutting edge and directly heat the blade. (see heated knifes). In addition ground points (point heaters) or comb structures for particular applications are possible.
