This straight-in electric cartridge heater is specially designed for aluminum extrusion barrels, an upgraded heating solution replacing traditional external band heaters. Different from external heating modes, this heating tube adopts internal direct insertion installation, realizing zero heat loss through air gap and greatly improving overall heating efficiency.
Made of high-temperature resistant 310S stainless steel sheath and imported Ni80Cr20 heating wire, this extrusion heating rod supports max continuous working temperature up to 450℃. It features even heat distribution across the whole extrusion barrel with temperature deviation within ±2℃, solving common production troubles including uneven barrel temperature, unstable aluminum billet fluidity and defective aluminum profiles. Compared with conventional band heaters, it cuts power consumption by over 30% and extends service life to 3-5 times.
We provide optional 2-section or 3-section segmented independent heating to match different aluminum alloy extrusion processes. All specifications including length, diameter, voltage and power can be fully customized to fit 500T to 3600T aluminum extrusion presses. With built-in overheat protection and leakproof structure, it fits 24-hour uninterrupted industrial heavy-duty operation.
All heating tubes pass strict high-temperature aging tests and come with CE & RoHS certifications. We offer 12-month warranty, fast delivery and professional technical support. Ideal durable and energy-saving heating replacement parts for global aluminum extrusion factories.
