Description
The cast-in heating plates and heating bands consist of one or several electrical resistances embedded in a block of aluminum, brass, bronze or cupronickel alloy providing excellent thermal conductivity.
Cast-in heating elements are ideal for applications requiring homogeneous indirect heat. Cast-in heaters are often used in the plastics industry, packaging industry, food industry and many others.
We can make cast heaters according to your specific drawings, the cast heater is very reliable as the elements inside always have a heat transfer surface and this ensures that the heater is less likely to fail. The heat is also distributed evenly ensuring better product production and longer element life than other heating elements.

Features
1. Gravity molding ensures an excellent material homogeneity and thus a perfect heat transfer.
2. Constant surface temperature is achieved through appropriate forming.
3. As this is indirect heating, the heating resistance is protected. The solid or fluid to be heated is not in contact with the resistance.
4. High protection against corrosion
5. The end-to-end control of the design and production chain allows us to deliver a product which suits your process perfectly
6. Resistance in severe industrial surroundings (impacts, vibration)
