Flat ceramic heaters

Flat ceramic heaters are used to heat plates and molds for high temperatures. The heating elements here are wires and resistance tapes wound on a micanite insulator.

Technological processes

Heater design
Winding a heating spiral
Completion the heating element with ceramics
Making a power connection according to the design
Laying ceramic fittings

Construction

Specification

High-quality ceramics allow to achieve high power and high temperatures on the surface of the heater. Appropriately dense winding of the resistance element ensures an even temperature over the entire surface. The individual design of the winding of the resistance element allows to make holes / cutouts exactly according to customer needs.

It is possible to install a ceramic heater in a cover sheet metal, metal boards (e.g. aluminum, stainless steel) or heating tables.

Types of current outlet

Wires
Beaded strand

Technical specifications

Ceramic heaters can be made with different power distribution. Appropriate distribution of heating power density on the surface of the element gives the ability to control the temperature. This technology is used to eliminate heat loss at the ends of heaters and to heat selected zones.
