There are many types of mold heating tubes, and some special specifications of heating tubes on the market also support non-standard customization. But in the actual use process, some details are often overlooked. The following small series will take you through these issues.
1. When we turn on the power, the voltage should not be higher than 10% of the rated voltage. If the voltage is lower than the rated voltage, the heat generated by the stainless steel mold heating tube will also drop.
2. For some reason, the original power supply of the mold heating tube is partially powered out. It must be noted that the stainless steel electric heating tube must be cooled before connecting to the power supply. Since every time the mold heating tube is energized, the current will produce an electric impact on the mold heating tube, so the mold heating tube is impacted again after one electric shock and is more likely to burn out.
3. In a humid working environment, the insulation performance of the mold heating tube will be reduced, resulting in short circuit and breakdown.
4. When using mold heating tubes in chemical corrosive agents, flammable and explosive liquids/gases, etc., the wiring part can be protected by an insulating sealing device.
5. If there is thick oil scale on the surface, it should be removed regularly, if it is not removed regularly, it may reduce the heat transfer performance of the mold heating tube.
6. The mold heating tube should be stored in a dry environment. If the surface is damp due to long-term storage, the solution is to put the heating tube into a drying oven for drying.
