The origin of the single-head electric heating tube: (single-head) or (cartridge) electric heating tube (Cartridge Heaters). In China's electric heating industry, there is a model called M3 for a long time. In the late 1990s, electric heating tubes were widely used in China, and the shapes of electric heating tubes were also present. In southern China, this kind of one-end electric heating tube for molds is called a single-head electric heating tube, which is very similar. In foreign countries, it is called a cartridge heater, which is also a kind of image, because the shell of the cartridge is cylindrical and one end is blocked. It is ingenious to call it a single-head electric heating tube in China.
Single-head electric heating tube application range:
1. Mold heating has been accepted by a wide range of customers in modern industrial applications.
2. Heating system in plastic machinery.
3. Pharmaceutical production line.
4. Laboratory heat treatment test.
5. Chemical industry, etc.
Single-head electric heating tube
Single-head electric heating tube performance requirements:
1 Heating time
Under the test voltage, the time for the component to rise from the ambient temperature to the test temperature should not exceed 15min
2 Rated power deviation
Under the condition of sufficient heat, the deviation of the rated power of the component should not exceed the range specified below;
For components with rated power less than or equal to 100W: ±10%.
For components with a rated power greater than 100W, it is +5%～-10% or 10W, whichever is greater.
