Medium density cartridge type MC


The medium watt density cartridges are designed to heat solids by conduction. They are usually used to heat press moulds.

Maximum operating temperature of high watt density cartridge 500°C, maximum load 12W/cm² (77W/Sq. Inch).

Technical specifications:

  • Resistive alloy wire nickel chromium 80/20 coiled
  • Insulation by compressed magnesium oxide
  • Sheath in stainless steel tube 321 tolerances on diameter ±0.02mm, end plug seamless welded
  • Metric diameter 8, 10, 12.5,16, 20 mm
  • Imperial diameter 1/4″, 3/8″, 1/2″, 5/8″
  • Length from 25 to 1500mm, 1 to 60”
  • Termination by nickel cable glass fibre insulated, length 300mm (maximum temperature 280°C)
  • Voltage 230 V
  • Power from 100 to 2000W

Possible variations:

  • Special cable length up to 2000 mm
  • Additional wire for earth
  • Special voltage up to 440 V
  • Built in thermocouple type K or J
  • Welded threaded gland for fixing metric or BSP
  • Welded Flange or bracket for fixing


The high watt density cartridge must be fitted in a reamed hole to work properly.

The layout of cartridge in the part to be heated must be on a regular pitch. The minimum distance between 2 cartridges is 40mm.

You must use a temperature control device to regulate the temperature of your process.  The sensor must be fitted in the middle of the cartridges.
