The cast aluminum electric heating coil is a tubular electric heating element as the heating element, the element is bent into a mold, and the aluminum is cast into various products. It can be closely attached to the heated body, has the characteristics of uniform heating, good thermal conductivity, and long service life. This product is currently one of the ideal heaters at home and abroad.
The mica heating ring is made of high-quality nickel-chromium alloy heating wire as the heating element, and natural mica is used as the edge layer assembly. The outer layer is made of high-quality stainless steel as the conductive heating layer. The mica heating ring can be machined according to the needs of users. Rings, plates, and various special-shaped products.
The difference between the two:
1. Different advantages and disadvantages
The cast aluminum heater has a long life, good heat preservation performance, strong mechanical properties, corrosion resistance and anti-magnetic field. There is a heat preservation device on the outer surface, and the inner radiating surface is sintered with infrared rays, which can save electricity by 35%
The performance advantages of stainless steel mica heating coil: reasonable structure, beautiful appearance, stable performance, uniform heating, fast heat dissipation, long service life, good edge performance, high pressure resistance, etc.
2. Different materials
The cast aluminum electric heating coil is a tubular electric heating element as the heating element, the element is bent into a mold, and the aluminum is cast into various products. It has the characteristics of fast heat transfer, hard and not fragile, high temperature not deformed and not easy to age.
Stainless steel mica heating ring uses stainless steel and mica as raw materials. It can be used for small-size heating for nozzles and for heating on plastic machine barrels without being restricted by size.
3. The high temperature of heating is different:
Cast aluminum electric heating coil 1. Operating conditions: ambient temperature -20℃～+60℃; relative humidity <80%. 2. Electric strength: It can be tested with 1500V50HZ sinusoidal alternating current, and there is no breakdown at 1M1N. 3. Temperature resistance: The temperature of the surface installed on the machine can be close to 400℃.
The high temperature of the stainless steel mica heating ring can reach about 200 degrees.
