The semi-circular electric heating tube design is not only advanced with high thermal efficiency and even heat distribution, but also, when current passes through the high-temperature resistance wire, the heat generated diffuses through the oxidized powder coating to the surface of the metal tube, then to the heated object or air, achieving the heating purpose. Moreover, it remains electrically insulated and non-charged during operation, ensuring safety.

The semi-circular electric heating tube features simple structure, long service life, high thermal efficiency, good mechanical strength, can be bent into various shapes, and is safe for use. It is commonly used for metal mold heating, die casting parts, pounder machines, dishwashers, immersion heaters, defrosting, and oven boxes; it can be custom-made to the required length and is suitable for applications where a small volume is needed with leads at both ends. Often used in mold-making, machinery manufacturing, metallurgy, conveyors, roller mills, and oven boxes, it boasts high density and reliable installation.
