The surface coating of the cartridge heater adopts a black superconducting material, which makes the electric heating tube work at a higher temperature.
This high-temperature heater cartridge is very suitable for printing high melting point plastic materials such as PEEK and PEI. It has stable performance and long service life in high-temperature working environments up to 900 ℃.
There is no recessed design on the top of the cartridge because the flat top has a larger and more uniform heating area, the power density becomes smaller, and the service life of the cartridge is prolonged.
DNR our company is a professional heater cartridge manufacturer. In the past 5 years, we have enjoyed a good reputation as the partner of several famous European 3D companies. We have the know-how to keep the heater’s wattage stable, which is essential for the printer’s performance. Meanwhile our heater has a long service life up to 10,000 hours with a warranty of 1 year. In the laboratory test, our heater can stand 2500 heating up cycles while the standard for UL is only 1000 heating up cycles. One cycle=0.5H power on+1H power off. As a factory, not a trading company, we are confident to have better control on quality, lead time and OEM requirements.
