Main uses of air-cooled cast aluminum electric heating coils

The cast aluminum ring is a tubular electric heating element used as the heating element, which is bent and formed into various products by pouring aluminum into the mold. It has the characteristics of tight fitting with the heated body, uniform heating, good thermal conductivity, and long service life. This product is currently one of the ideal heaters both domestically and internationally. The surface load can reach 3-5.0W/cm2. The heating temperature shall not exceed 400 ℃. According to user needs, an insulation layer can be added outside the heater, resulting in higher thermal efficiency and a savings of about 20% in electricity consumption. Mainly used for heating and heating plastic machinery, ovens, water boilers, pipelines, and non corrosive liquids.

1、 Main uses of cast aluminum heating rings

Cast aluminum heating rings are widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemical, rubber, petroleum and other equipment.

2、 Technical parameters

1. Usage conditions: ambient temperature -20 ℃~+60 ℃; Relative humidity<80%.

2. Electrical strength: Can withstand voltage 1500V50HZ sine AC withstand voltage test, and there is no breakdown phenomenon at 1M1N during withstand voltage.

3. Leakage current:<0.5MA.

4. Insulation resistance:>2M Ω.

5. Grounding resistance:<0.1 Ω.

6. Power deviation value:+5%~-10%.

7. Temperature resistance: Installed on the machine, the surface temperature can reach nearly 400 ℃

The heating equipment of the injection molding machine adopts an electromagnetic heater for energy-saving transformation, which has the following advantages:

1) The product has excellent power saving performance, which can save 40-70% of electricity bills, and has a high return on investment.

2) High thermal efficiency, reducing preheating time by 1/2 to 2/3.

3) Intelligent operation, safe and reliable, long service life, and reduced maintenance costs.

4) The surface temperature is low and can be touched by hand, making the plastic production line no longer hot and difficult to handle.
