1. For mold heating: (single head) or (cartridge) electric heating tube (Cartridge Heaters), in the Chinese electric heating industry, there is a long-term model: M3. In the late 1990s, due to the wide application of electric heating pipes in China, the shape of electric heating pipes is also very large. In southern China, the electric heating pipes for such a outgoing mold are called single-head electric heating pipes, which are very similar. It is also called the cartridge heater in foreign countries. It is also called the image. Because the cartridge shell is cylindrical and one end is blocked, it is a coincidence with China that it is called a single-head electric heating tube. 2, liquid heating: U-shaped electric heating tube (U) Modality Screw Plug Immersion Heaters, Screw Plug Immersion Heaters, Flange Immersion Heaters. Some types of electric heating tubes are filled with water, oil, thick liquid, alkali solution, acid solution or the like or in a pressure tank. Application: Mold heating is widely accepted by customers in modern industrial applications. In the plastic mechanical heating system, pharmaceutical production line, mold application heating, laboratory heat treatment test, chemical industry, etc., the mold heating system is constantly creating for China's modernization. A better new height. In industrial water tank applications, liquid heaters can be used in a variety of environments, harsh climates can be adapted, in the cold transport of various liquid insulation, mixing and heating of various solutions, food machinery heating, etc., liquid heating system is more capable Adapt to the needs of all kinds of whimsy.
