Product characteristics

The surface load of the cast aluminum heater can reach 2.5-4.5w/cm2, and the maximum working temperature is between 300-450 ℃; The surface load of the cast copper heater can reach 3.5-5.0w/cm2, and the maximum working temperature is between 500-600 ℃; The surface load of the cast iron heater can reach 4.5-6.0w/cm2, and the maximum working temperature is between 550-700 ℃.

Metal casting heaters use tubular electric heating elements as the heating element and are bent into shape. They are centrifugally cast into various shapes using high-quality metal alloy materials as the outer shell into the mold, including circular, flat, right angle, air-cooled, water-cooled, and other special shapes. After precision processing, it can closely fit the heated body. The metal casting heater is an efficient and evenly distributed heater with excellent thermal conductivity of a metal alloy, ensuring uniform hot surface temperature and eliminating hot and cold spots in the equipment. It has advantages such as long service life, good insulation performance, strong mechanical performance, corrosion resistance, and magnetic field resistance. Adding insulation devices to the external heat dissipation surface and sintering infrared radiation on the internal heat dissipation surface can save 35% of electricity consumption.

Main purpose

Widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemicals, rubber, petroleum and other equipment.

matters needing attention

1. The working voltage shall not exceed 10% of the rated value; The relative humidity of the air shall not exceed 95%, and there shall be no explosive or corrosive gases.

2. The wiring part should be placed outside the heating layer and insulation layer, and the shell should be effectively grounded; Avoid contact with corrosive, explosive media, and water; The lead wire should be able to withstand the temperature and heating load of the wiring section for a long time, and excessive force should be avoided when tightening the wiring screws.

3. The metal casting heater should be placed in a dry place. If the insulation resistance is lower than 1M Ω due to long-term storage, it can be baked in an oven at around 200 degrees Celsius for 5-6 hours to restore normal operation. Or reduce the voltage and heat it up until the insulation resistance is restored.

4. The metal casting heater should be positioned and fixed properly, and the effective heating area must be tightly attached to the heating body, and empty burning is strictly prohibited. When dust or pollutants are found on the surface, they should be promptly cleaned and reused to avoid affecting heat dissipation and shortening service life.

5. The magnesium oxide powder at the outlet of the electric heating tube should be protected from pollutants and moisture infiltration in the use site to prevent leakage accidents.

specifications

1. Cast aluminum and cast copper heaters: Cast tubular electric heating elements into different shapes by pressing them into aluminum and copper solutions. Mainly used for heating and heating plastic machinery, ovens, water boilers, pipelines, and non corrosive liquids.

2. Cast iron heater: Casting electric heating pipes into iron solution, widely used in die casting machines of manufacturers such as locks, zippers, hardware, toys, etc. The nozzle heater is also known as a gooseneck heater. There are two types: one is to cast the electric heating tube into red copper, and the other is to cast the electric heating tube into iron.

3. Other electric heating castings with special needs: Various specifications of electric heating castings can be customized according to customer needs.

Uniformly distribute high-temperature resistance wires in high-temperature resistant stainless steel seamless pipes, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. This structure is not only advanced but also has high thermal efficiency,
