Cast Aluminum Electric Heater, various specifications of industrial and civil electric heating castings, mainly include:
1. Cast aluminum and cast copper heaters: tubular electric heating elements are cast into aluminum or copper solutions to form heaters of different shapes. Mainly used for heating plastic machinery, ovens, water boilers, pipelines, and non-corrosive liquids.
2. Cast iron heaters: electric heating tubes are cast into iron solutions, widely used in die-casting machines for lock, zipper, hardware, toy manufacturers. Nozzle heaters, also known as gooseneck heaters, are divided into two types: one casts the heating tube into red copper, the other casts it into iron.
3. Other special electric heating castings: various specifications can be customized according to customer needs.
Ordering instructions:
1) Customers should provide product drawings or samples; if not available, provide product specifications, model, voltage, power, etc.
2) Surface power density is between 2.5 and 4.0 W/cm².
3) Surface power density for cast copper heaters is between 3.5 and 5.0 W/cm².
Cast aluminum heater, cast copper heater, cast iron heater, usage instructions:
1. Operating voltage must 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. Cast aluminum and cast copper heaters should be stored in a dry place. If the insulation resistance is below 1MΩ due to long-term storage, bake in an oven at about 200°C for 5-6 hours to restore normal.
