1. The diameter of the single-head heating pipe must be closely matched with the hole diameter of the die hole. Usually, the gap between the two is less than 0.1mm. For example, the heating rod of the pipe diameter 10 should be the hole diameter within 10.1.
2, the installation hole should be processed to ensure its coaxiality and size tolerances, such as the use of reamer and other tools to process the processing.
3. Before the installation of the mold electric heating tube, the residue left in the processing should be cleaned, such as organic oil and other residues, which will be carbonized after heating, thus affecting the ability of heat conduction.
4, the use of the design voltage will not be a problem, the actual power when using can be calculated according to the following formula:
[use voltage / design voltage] * [use voltage / design voltage] * design power = power when used (example ) The electric heating tube with rated voltage and power is 230V 500W. When the voltage is 220V, the power used is 418.6W, which is about 84% of the rated power.
