Cartridge Heating Elements
Cartridge heating elements are devices which provided
localized heating for a wide range of applications. These heaters are generally
inserted into a substance or are position to heat a certain area. These items
typically manufactured from seven different parts including: heating coil,
insulation, sealing, sheath, watt density, lead wire type and termination. The
electric coil is encased inside a metal sheath which is insulated with ceramic,
mica, mineral or fiberglass material. The type of insulation is based upon the
desired wattage and application for the heater. It is important to note that
the insulation is a required component because contact between the heating coil
and sheath could cause short-circuiting. Sheaths can be constructed from a
variety of materials including aluminum, copper, iron, nickel and stainless
steel.
When installing cartridge heating elements there are a
number of factors to consider such as proper wattage and heat temperature.
Cartridge heating elements are utilize for various applications and industries
such as food services, fluid heating, hot plates, semiconductors, shrink wrap
machines, labeling machinery, die cutting, mold forming, packaging, hot
stamping, sealing printing, plastic processing, rubber forming and much more. Cartridge
heating elements will often be inserted through a close fitting hole and will
have a surface thermocouple or remote microcontroller. The amount of heat is based upon how much electricity is encountering the resistance and many types of cartridge heating elements can adjust their temperatures for a specific application.
