■What is a Cartridge Heater A cartridge heater is a pipe-type heater widely used in molds, packaging machines, molding machines, and more. It primarily consists of nichrome wire (the heating element) wound around a molded piece of magnesium oxide called a bobbin, which is then placed inside a metal pipe such as stainless steel. After filling with magnesium oxide powder, the heater undergoes a squeezing process to increase the filling density of the magnesium oxide, allowing it to release more heat to the outside of the heater pipe. This makes it an excellent heater. The principle of the cartridge heater is based on resistance heating, as it uses nichrome wire as the heating element. ■Types of Cartridge Heaters The types of cartridge heaters include flanged cartridge heaters, threaded cartridge heaters, small-diameter cartridge heaters, high-temperature cartridge heaters, L-shaped cartridge heaters, side lead type cartridge heaters, two-circuit cartridge heaters, cartridge heaters with built-in thermocouples, copper pipe cartridge heaters, coarse and fine winding (balanced winding) cartridge heaters, and various heaters for plastic molding machines and industrial machinery.

The principle of the cartridge heater is based on resistance heating, as it uses nichrome wire as the heating element. ■Advantages of Using L-Shaped Cartridge Heaters Since the lead wires are oriented in an L direction relative to the heater, there is no need to forcibly bend and route the lead wires. This helps prevent wear on the lead wires. Additionally, because they are oriented in the L direction from the start, if there is no space near the heater's sealing area, it is possible to route the electrical wires in that space.
