Cartridge heaters are one of the most reliable and longest-lasting heating elements currently available. Why do they fail sometimes? In most cases, this is because you have not installed or maintained it properly.


In order to maximize the life of the cartridge heater, there are things you should and should not do. As experts in this field, we think we have some understanding of the subject. Here, we provide some tips on how to take care of your products and prevent unnecessary failures and failures in the future.


Three tips to maximize the life of the cartridge heater

1. Avoid pollution

In order to maximize the use of cartridge heaters, the leads must be protected from potential contaminants. This includes liquids and gases, such as oils, sprays, lubricants, etc. If any of these substances enter the heating element, it may cause a short circuit and eventually cause a malfunction.

It’s also worth noting that every time your cartridge heater expands and contracts, it draws in air from the surrounding environment. Any moisture or impurities in the air will negatively affect the function of the heater. Therefore, it is important to purchase heaters with proper seals.


2. Make sure the heating element fits tightly

The cartridge heater is incorrectly sized and will usually fail prematurely.


The component should be close to the mold. Otherwise, the heat will not be effectively transferred, and the heater will start to operate at a higher temperature than the required temperature. Over time, this overheating can adversely affect the equipment and shorten the life of the heater.


As a general rule of thumb-in order to efficiently dissipate heat as quickly as possible, the diameter of the mold should be no more than 0.1mm larger than the diameter of the heater.


3. Prevent excessive cycling

If the wattage of the cartridge heating element is higher than the required power, it will turn on and off at a rapid rate (for example, every 30-60 seconds) to maintain the desired temperature. This is called excessive temperature cycling. It quickly oxidizes the resistance wire and often causes heater failure.


In order to avoid excessive circulation, it is worth studying. Before purchasing a heater, always establish a minimum power to meet your application requirements.
