There are many varieties of specifications for cartridge heater on the market, which are used and used in today's society. Some customers do not understand the classification of cartridge heatersaccording to other requirements. Here we have sorted out the four common classifications of single-head heating pipes: 1. cartridge heaterscan be divided into detailed according to their own shapes: 1. Micro-single Head heating tube: diameter Φ2.2 ~ Φ5.9mm. 2. Specification of single-head heating tube: diameter Φ6～Φ25mm. 3. Large single-head heating tube: diameter Φ25～Φ100mm. 4, two semi-circular single-head heating tube: two semi-circular single-head heating tube is an improved product of electric heating element for general single-end mold. It is made up of half of a semi-circular electric heating element, and after using half of it, it rises itself. The force and the die hole reach close cooperation, and the power density is large, the service life is long, and the heat efficiency is superior. It is the replacement product of the single-end heating element of the mold, especially the mold heating with high demand temperature and fast heating speed. 5. Flat single-head heating tube: This product is most effective as a heating element in a mold under special conditions, and is used in some tapped mold holes. And other equipment vendors. 6. Hollow single-head heating tube: Use a hollow tube with a single-head tube to quickly heat the air. 7. Cone-type single-head heating tube, square single-head heating tube These two cartridge heater are most effective as heating elements in the mold under special conditions, like some taper mold holes. Second, according to the export specifications can be divided into: 1, soft lead single-head heating tube: stainless steel soft wire from the inside of the heating tube, put a fiberglass casing on the outside. This technology is low in cost and is not easy to break. 2. External wiring cartridge heater : stainless steel hard wire is taken out from the inside of the heating tube, and the high temperature line is connected from the outside. This technology is a specification technique. 3, the inner lead cartridge heaters: the high-temperature line is directly drawn from the inside of the heating tube, this technology is expensive, but it is not easy to break the line. Third, according to the technical specifications can be divided into: 1, PTC Automatic Temperature Control Electric Heating Tube: the use of rare earth metal instead of the traditional electric heating wire produced, the commodity he can use the resistance characteristics of rare earth metal to automatically control the temperature. 2, high-density cartridge heaters: the use of magnesium oxide rods for external winding production. 3, low-density cartridge heaters: made of magnesium oxide tube. Fourth, according to the power cartridge heaters can be divided into: 1, low power density. 2. High power single head tube. 3. Medium power cartridge heaters. 4, ultra high power cartridge heaters.
