Heating is an essential manufacturing method used in a number of industries. Electric industrial heaters with differing designs, watt densities, and temperature variations are employed to attain this method. Cartridge heaters are one of the electric industrial heaters employed in several industries, such as plastics, metals, packaging, and immersion heating. These heaters have increased in popularity over many years and are now utilised for various industrial heating activities.

This post provides an overview of cartridge heater applications in different industries with significant elements and the working process.

What is a Cartridge Heater?

These heaters can be recognised by their tube-like formation, which makes them adaptable. They can heat metal constituents by embedding them straight into holes. These heaters, similar to various forms of industrial heating tools, can be made with varied watt densities to match different tasks effectively.

What are the Significant Elements of a Cartridge Heater?

It is constructed using a resistance coil covered all over a dielectric ceramic core. For enhanced security, the whole framework is then closed with metal. These heaters are powered by unstable or alternating current. The current flowing through a resistance coil in a heater makes it hot. That heat is transferred to the protective covering and, finally, to the enclosing environment. The term conduction is employed to indicate this method of thermal energy transmission.

The Cartridge Heater Applications

1. In Hot Stamping

Hot stamping is a mechanism that employs heat and pressure to relocate a design or brand onto an exterior. Cartridge heaters made by manufacturers in India are utilised to heat the stamping die prior to pressing it into the outer covering. These heaters are the best option for this procedure as they need appropriate and constant heating.

2. Plastic Injection Molding

One of the essential cartridge heater applications is generally seen in injection molding equipment. They are utilised to heat and keep up the mold’s temperature. This is important because if the mold is very cold, the plastic will not move perfectly, and if the mold is very hot, the plastic will disintegrate. Since these heaters offer appropriate and homogeneous heating, they are perfect for this task.

3. Medical Devices

One of the most effective cartridge heater applications is to heat the device to a definite temperature in order to make sure that it is safe to use. As they offer complete and uniform heating, cartridge industrial heaters are heating medical devices.

4. Mold Temperature Controller

Cartridge heaters are employed in mold temperature controllers to heat and manage the temperature of the mold.

5. 3D Printing

3D printing is another cartridge heater application for printing beds in 3D printers. This is essential because if the print bed is very cold, the printed entity will not stand by it. Since they provide precise and continuous heating, they are perfect for 3D printing.

6. In Processing Food

They are employed to set the equipment to a particular temperature in order to make sure that the food is properly cooked. As they provide complete and compatible heating, cartridge heaters are the best for processing food.

7. Plastics Welding

In plastic welding, cartridge heaters are used to heat the plastic to a predisposed temperature. This is compelling because if the plastic is not adequately heated, it will not weld properly. As they provide proper and identical heating, they are effective in the plastics welding industry.

How does a Cartridge Heater Work?

1. A cartridge heater involves a resistance coil wound all over a ceramic core that is covered by dielectric and protected in a metal sheath.

2. Powered heat transmitted by the coil to the sheath makes the sheath warm up. This heat is then transmitted to the inner metal part, which needs heat.

3. General-purpose drills are normally enough to fix a cartridge heater in a low or medium temperature range (600°F or less) for running through holes. Holes can be drilled .003” to .008” above the given size of the drill, coming out as fits of .009” to .014.” While this fit is somewhat looser than optimal heat transfer, it helps in the set up and elimination of cartridge heaters, specifically those with extended sheaths.
4. At high densities, an adjacent fit is very important. The holes must be drilled and stacked apart from being drilled with only a normal bit. With a very tight fit, the heater will remain cool and have an extended life expectancy.
