[Description of Conventional External Wiring Single Head Heating Tube]
The conventional external wiring single head heating tube is called "conventional" because of its simple external structure, without accessory threads, limit devices, protective sleeves, etc. This type of heating tube commonly uses the structural process of external wire winding and single ended lead wire, and is used for heating in molds, packaging machinery, sealing machinery, etc. I will introduce its performance from the following points:
1. High efficiency: After in-depth research, high-precision products transfer heat without loss;
2. Long lifespan: The use of high nickel alloy heating elements has high temperature resistance and oxidation resistance, and the use of heat-resistant and high-temperature insulating magnesium oxide makes it significantly longer than traditional products;
3. Robustness: Adopting a structural design that can withstand mechanical vibrations and impacts during use, while fixing the baffle structure for easy fixation and use of the heating tube;
4. Electrical performance: It has excellent insulation performance, especially able to maintain good insulation performance in cold state;
5. Operability: Even if multiple heaters are used simultaneously, they will not interfere with each other and wiring can be easily completed inside the box;
6. Types and models: Various types and shapes. There are metric and imperial sizes, regular and non-standard types, and customization according to customer requirements.
[Precautions for using conventional external wiring single head heating tubes]
The manufacturing process and material selection of heating tubes are certainly important, but if good things are not used well, they will become rotten. Therefore, understanding how to use heating rods correctly is also very important. The following will introduce several commonly used points:
1. The bullet tube electric heating tube itself has a high wattage density, and often due to poor heat transfer, the external tube body is burnt black, and the internal high temperature accelerates the aging of the electric heating wire, leading to the breakage of the electric heating wire.
2. Precision should be paid attention to when machining deep holes in molds, and drilling holes at both ends is not allowed because there are large pores at the junction that cannot be tightly sealed, resulting in poor heat dissipation of the electric heating tube and uneven temperature of the heated body.
3. Attention should be paid to the magnesium oxide powder at the outlet of the electric heating tube. It should not be contaminated or wet in the usage area to prevent leakage. It is recommended to reserve 5m/m outside the mold.
4. Use an electric heating tube when starting up, which can be preheated for 5 minutes to avoid the risk of electric leakage due to humid air or moisture infiltration into the tube. When using electric heating machinery, a grounding wire must be installed.
For electric heating tubes and heating tubes that have not been personalized, if they are molded, fastened, reduced in length, reduced in diameter, etc. according to customer requirements and do not affect secondary sales, they can apply for return or exchange within 7 days; For returns and exchanges without quality issues, the buyer shall bear the round-trip shipping cost.
