Description

Mica band heaters are also known as electric band heaters which is made with high-grade mica; the type and thickness of each mica insulating layer are carefully selected to provide excellent thermal conductivity and high dielectric strength. Similarly, to create a uniform heat distribution throughout the heater and to maintain the lowest possible resistive circuit temperature, an optimum combination of resistance ribbon alloy, cross-section and length are selected to design the resistance winding of each heater.

Mica band heater is rugged and heavy duty heaters made for applications that require high temperatures (up to 1400ºF) and high watt densities (up to 100 w/in2). These heaters are ideal for increasing output especially in injection molding and to meet the heating requirements to process newly engineered high tech resins. The nickel chrome resistive material inside a mineral insulated heater is embedded in Aluminum Oxide insulating medium which provides excellent heat transfer and dielectric strength. A stainless steel outside casing gives external protection.

In the field of industrial heating, mica band heater is made of nickel-chromium alloy heating wire as heating body, natural mica as insulation layer, and the outer layer is made of high stainless steel as conductive heating layer, which can be machined into various shapes according to demand.

Mica Band Heater For Industry use mica material as an insulating layer, which can effectively reduce heat loss and convert electrical energy into heat energy. Compared with the traditional heating method, the mica band heater can reach the required temperature in a shorter time, greatly improving the production efficiency. Regarding the safety performance, mica has good high temperature resistance and insulation properties, can effectively prevent leakage and short circuit and other safety hazards. In addition, its structural design is reasonable, can withstand a certain amount of mechanical pressure and impact, is not easy to damage, providing reliable safety for the operator.

The mica band heater for industry can maintain a stable heating temperature during long-term operation, and there will be no excessive temperature fluctuation. This is undoubtedly important for some production processes with high temperature requirements. The stable temperature can better make the quality of the product good and improve the pass rate of production. The adaptability of mica heating element can be produced according to different heating needs, suitable for heating equipment of various shapes and sizes.

When installing, mica band heater for industry should be closely fitted with the heated body to ensure that the surface of the heated body is flat and complete

To maximize the surface-to-surface contact, mica band heaters are carefully rounded and formed to optimize the grip on a machine barrel. The external metallic protective sheath of a is made of a special alloy, which expands less than the barrel when heated. This difference in thermal expansion makes the heater grip the barrel firmly once it is energized, and this improves heat transfer.

Band heaters are made in different construction styles, clamping mechanisms, and terminal types. Holes, cutouts, slots, thermocouple or mounting brackets can be accommodated in the design.

How to use the mica band heater properly?

1. Choose the appropriate Mica Band Heater

Ensure that the size and shape of the heater match the surface of the equipment. They are typically used to heat cylindrical surfaces.
Select appropriate power and voltage according to application requirements to ensure that the heater can provide the required heat.

2. Prepare to install the surface
Before installing the heater, make sure that the heating surface is clean, dry, and free of oil stains to ensure good thermal contact and conduction.

3. Install the heater
Place the Mica Band Heater in the target position of the device and secure it with appropriate fixtures or bolts. Most Mica Band Heaters come with built-in fixtures for easy installation.
When connecting the wires of the heater to the power supply, ensure that the connection is tight and well insulated to prevent electric shock or short circuit.

Advantage

1.Convenient operation:

The device of the band heater combines the new control technology, so the equipment is more convenient to operate, and the user-friendly design.

2.Quick heating

Because of the band design, the heating area is larger, and a large amount of heat energy can be generated in a short time, and heating is faster. And the band heater has the function of insulation to reduce heat loss.

3.Energy saving and environmental protection

As an electric part,mica band heater change the electric engergy into heat energy,the shell material is stainless steel,so the heat speed is very fast,meet the modern concept of green production.

4.More safe

In the design and structure ,the medium and power is seperate,so high temperature will not influence the power,more safe.

Main Feature

1.Heat-resistant, endure high temperature as 600℃.

2.Good insulation property,insulation resistance is bigger than 100MΩ.

3.Light weight, thin thickness,small volume,big power.

4.It can be easily designed any shapes according to demand, low cost.

Notice

Do not bend 1 piece heaters

To provide close contact with heating surface, tighten clamping bands while taping around the outside of band heaters. After heat-up, occasionally re-tighten the clamping band.

To tighten post terminals, bottom nut should be held in place while tightening top nut (to avoid putting stress on terminal).

Avoid spilling oils, grease, water or molten plastic on leadwires, post terminals or ends of heaters.

Do not pull on leadwires with a force exceeding 15 lbs. Select the band heater whose diameter most closely approximates the diameter of your part.

Beyond the heating of a sheath and its contents, band heaters are also used for shrinking.Playing on the phenomenon of expansion of metals, the outer element called hoop is heated in order to introduce the inner part, called hoop part and allow when the assembly cools, to make one and the other united.
