Explain the Construction of Cartridge Heater Main Parts

The Cartridge Heater is a useful material that can be utilised for the heating of dies, molds, medical apparatus, hot stamping, and more. These heaters have a tube shape, are heavy and best suited for the heating industry. The heaters have a compact design and can deliver a watt density of up to 100w/cm². Understanding its construction will clear you some things about it. Let’s enter into this in more detail:



Cartridge Heater Construction Parts Described

The construction of this heater is pointed out below. These are the seven parts explained below:

  • Insulation

The heater comes with the insulation feature that would prohibit the Nichrome coil from contacting the sheath. It’s an event that can produce a short circuit as the sheath can melt and turn into an apparatus failure. You can lower the damage by installing the ground fault that’s interrupting the circuit. You can support the coil from touching the sheath. To do this, insert the coil in the sheath and fill it with magnesium oxide. 

  • Sealing

Once the heater is filled with MgO, the seal will apply to the open end of the heater. The process will prohibit the coil and MgO to come out and restrict the contaminants like air, moisture, and plastic debris from entering the heater. 

  • Termination

As we installed these heaters in the wide machine ranges, the Cartridge Heater Manufacturers in India have to design these heaters to meet up certain departures. These heaters can be ended with leads that appear straight or at the right angle. The makers should be careful about exposure to a temperature that’s higher than the maximum rating of the lead wire. To prevent lead wire damage from temperature, contamination, or movement, you can cover this using the metal conduit, silicone sleeves, and braided metal. 

  • Heated Coil

It’s an important part of a heater. The heating coil is the resistance where the electrical load occurs. The common type of metal alloy accepted for it is the nickel-chromium mixture known as Nichrome. We wound this type of wire around a ceramic core where the number of spirals will vary as per the requested watt density. The potential from the ac can either be 2 or 3 phases. The current flows through the coiled Nichrome wire that heats the wire that ignites the heater sheath.
