PRODUCT OVERVIEW ③ HIGH WATT CARTRIDGE HEATER
Q Characteristics The capacity of the high watt cartridge heater has increased significantly to 60W/cm 2 watt density while the normal cartridge heater has a watt density of 15W/cm 2 . Therefore, it is possible to select up to 4 times the W capacity of the normal product. When selecting 4 times the W capacity, the time required to increase the temperature can be shortened to 1/4 by the calculated value. Q Component Drawing Compared to a normal cartridge heater, the heating wire winding pitch interval is made finer and the heating wire is wound four times as much as in the normal cartridge heater.
Q Installation method and precautions • Due to the high watt density, the recommended hole tolerance on the plate side should be set within + 0.03 with respect to the D dimension. • For the method of installation and precautions for use, refer to Outline of Cartridge Heater.

[Comparison conditions] The same mold is heated with a high watt cartridge heater 4000W and a normal cartridge heater 2000W. We set the upper limit temperature to 200 degrees and compared the time required for the temperature to rise.
[Result] • It took about 2 minutes for the high watt cartridge heater to heat up to 200 degrees • Normally, it takes about 6 minutes for the cartridge heater to heat up to 200 degrees • The high watt cartridge heater shortens the time required to increase temperature by about 4 minutes ※ The above values are measured values and not guaranteed values. The actual value will be different from the above as the values may change depending on the characteristics of the un–heated work piece (shape, size, material, heat dissipation), heater arrangement and various other conditions.
