Many heaters factory ask us"what machines needed to produce cartridge heaters?" As a leading cartridge heaters machines factory in China, we would like to share our machines to make cartrdge heaters with you.
A cartridge heater is a tube-shaped, heavy-duty, industrial joule heating element (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density,based on its intended application. Highly compacted they reach a surface watt density of up to 50 W/cm².
It may be used to heat any kind of substance or material, such as oil, air, or sugar. However, a common application are plastic pellets, which are melted in order to form molded plastic parts. An example of such a process is the "hot runner" process. Cartridge heaters resemble tubular heaters structurally but tend to have higher watt densities.
To make cartridge heaters, you mainly need below machines:
pipe cutting machine - cut the tubes according to the length needed
Welding machine - welding the heater tubes
DRS-23 PLC resistance coil winding machine - coil the resistance wire
MGO powder filling machine - fill MGO powder to the tube
DG30 sawging machine - reduce the tubes after filled MGO powder, to make the density higher
polishing machine - polish the tube, to make the heaters surface more slick.
