The heating ring is made of stainless steel and mica. The size and power of Shanghai heating ring are not limited in the manufacturing process. It can be heated by shooting nozzle or plastic machine barrel. Shanghai heating ring has the functions of reasonable structure, beautiful appearance, stable performance, uniform heating, fast heat dissipation, long service life, good insulation performance and high voltage resistance.
Product Installation Guidelines:
Installation and replacement of electrothermal components, first check the power on.
Before installing the electrothermal element, determine whether the voltage value is consistent with the scale voltage of the electrothermal element.
Check whether the contact surface of the device position is flat and there is no concave and convex phenomenon.
Avoid contact with moisture in electrothermal components to avoid affecting insulation performance.
Check whether the electrothermal components are damaged and avoid impact deformation during installation.
The fixing screw must be locked during installation to ensure good contact.
Check whether the power supply and temperature control wires are damaged or damaged.
The connection between the power cord and the electrothermal element is locked to avoid short circuit caused by loosening of the power cord.
In some areas, the voltage amplitude is large, so the power supply should be selected to extend the service life steadily.
