How can I know the voltage and power of the electric heating tube of the mold?

- Jul 03, 2019-

The voltage and power of the electric heating tube of the mold can be analyzed from the following points:


1. When the electric heating tube is manufactured, the manufacturer performs laser marking on the surface of the electric heating tube to engrave voltage and power;


2, if it is not clear because of the long-term use or because the stain is the surface of the lettering, you can calculate the power of the electric heating tube by measuring the resistance value, voltage * voltage / resistance - = power;


3. If the heating tube does not measure the resistance value, it indicates that the heating tube has been broken. You can find a professional electric heating tube manufacturer, provide the corresponding size, working temperature, voltage, etc., can design the appropriate power.
