Instructions:

1) The working voltage shall not exceed 10% of the rated value;

2) The wiring part should be placed outside the heating layer and insulation layer, and the shell should be effectively grounded.

3) Should be placed in a dry place, if the insulation resistance is less than 1M due to long-term placement, it can be baked in an oven of about 200 degrees Celsius for 5-6 hours, and then it can return to normal.

Cast aluminium electric heater is a kind of high efficient and uniform heater with excellent thermal conductivity of metal alloy, which ensures uniform temperature of hot surface and eliminates hot and cold points of equipment. It has the advantages of long life heat preservation, strong mechanical properties, corrosion resistance and magnetic field resistance. Increasing the heat preservation device on the external heat dissipation surface and sintering the infrared ray on the internal heat dissipation surface can save 35% of the electricity consumption.

Cast aluminium heater is a kind of Diecasting electric heater with tubular electrothermal element as heating body and high quality aluminium alloy as shell. Its temperature is generally between 150 and 450 degrees Celsius. Cast aluminium heater plate manufacturers can be widely used in plastic machinery, die head, cable machinery, chemical industry, rubber, petroleum and other equipment.

High-frequency, high-current flow at high frequencies is wound into annular or other shaped heating coils (usually made of copper tubes). Thus, a strong magnetic beam with instantaneous polarity change is generated in the coil. When metal and other heated objects are placed in the coil, the magnetic beam will run through the whole heated object. In the direction opposite to the heating current inside the heated object, a corresponding large eddy current will be generated. Because there is resistance in the heated object, a lot of Joule heat will be generated, which makes the temperature of the object itself rise rapidly. To achieve the purpose of heating all metal materials.
