Aluminum Cast Heaters offer a high quality and efficient method of heating and controlling Extruders, Compression Molding Platens, Heat Sealers, Vacuum Forming Platens.Aluminum Cast Heaters can be casted into any shape and size needed, thus fully covering the part to be heated and virtually becoming the part itself. Most Cast in heat cool bands are made to customer specifications

Ceramic Heaters are used for plastic molding, extrusion and molding presses or any application where there is a need to apply heat to a cylindrical surface.They are very energy efficient since they have a standard 14in thick insulation. A 12in thick insulation is optionalUp to 18in diameter it can be a 1 piece construction, greater than that we recommend a 2-piece construction.Ceramic Band heaters can be manufactured in widths much greater than what is practical in Mica Band heaters, eliminating heat losses between gaps in narrow band heaters and simplifying installation

The specialty of Sheatwells ceramic infrared heaters lies in its external stricture. The flat shape of heaters gives them a flexibility to be used with more comfort. They look like a new-age product. There are several advanced features incorporated in these heaters making them better than general heaters.The element wire, of ceramic infrared heater, is embedded in glazed refractory which protects the wire from atmosphere to get longer life.Ceramic Flat Infrared Heaters are constructed by a firmly burnt-in heating coil. They consist of high heatproof resistant wire.

Mica Band Heaters are most widely used band heaters in industries due to its versatile design and rugged construction.Mica Bands has sheath Temperature capabilities up to 800F (425C).It provides excellent thermal conductivity and heat is transfer by ConductionDue to its good heat transfer capability faster heating up and cooling down possibleA stainless steel sheath encases a compressed mineral refractory which surrounds a helical or sinuated resistance element.These heaters are used for plastic molding, extrusion and molding presses, pipe heating, heat treating and autoclaves, food industry and many more.

Tubular heaters are most common type of heater which is used to heating air and gases.It gives superior heat transfer.Tubular Heaters are very durable and easy to install.Superior grade Magnesium Oxide insulation is used in tubular heatersThese tubular heaters available in Chrome Nickel Steel.To prevent from moisture its edges are sealed.

A Mica Strip heater is a device which is mounted on a surface and used to heat the surface or air.Available in various lengths and configurations. Mica strip heaters are constructed by winding of Nickel Chrome ribbon around mica insulation and encapsulated in stainless steel sheath.They are available in an extensive variety of sizes and shapes with option for hole, notches and cut-outs. These heaters mostly used in plastic processing applications and for anywhere heat is needed on curved or flat surface.

Cartridge heaters are used for heating metal parts and also used in threaded bushings for liquid heating for certain applications.Widely used to heat the plastic injection molds, dies, hot plates, platens and many more applicationsCartridge heaters are very economical and versatileThe use of high purity MgO insulation assures high dielectric strength fast heat transfer efficiencyThese cartridge heaters designed for high or low watt density.It consist of helically wound resistance coil made from nickel-chrome wire, evenly sketched and strung through holes in round ceramic insulator.

The ceramic band Heater design consist of a helically wound resistance coil made from Nickel-chrome wire, evenly stretched and precisely, strung through specially designed ceramic insulating bricks, forming a flexible heating mat. The ceramic heating mat along with ceramic fiber insulation is installed in a stainless steel housing made with serrated edges, providing maximum flexibility for easy installation. These are specially designed for energy conversation & improve the operation efficiency.

Advantages

1. Maximum watt Density in comparison to mica band heater i.e. 50 watt/ inch2
2. By the use of higher temperatures a faster off sequence is possible.
3. It is particularly suited to heat the cylinder with working temperature upto 500 oc(Sheath temperature 800 0c.)

Applications

1. Extrusion barrels & Dies.
2. Injection moulding.
3. Blow moulding Barrels
4. Blown Film
5. Compounding
6. Rubber machinery

Where uniform heat distribution and efficiency is important. Cast-in Heaters provide for better results the high thermal conductivity of aluminium allows precisely uniform temperature to be applied to the component surface, elevating hot or cold spots that may effect the equipments performance.Heat is provided by a tubular sheathed wire element that has long been recognized for its reliability, strength and adaptability.

Types

1. Air cooler cast-in heater.
2. Water cooler cast-in heater
3. Cast-in plate & round heater.
4. L & U shaped cast-in heater.
5. Customized designed cast-in heater.

Advantage

1. High thermal conductivity providing extremely uniform temperature over the whole heated surfaces.
2. Accurate temperature control-the high thermal conductivity eliminates any hot or cold spots that may occur with other forms heating.
3. Exceptionally long life.
4. Efficiencythe high thermal conductivity rapidly conducts this heat away from the tubular element to the component surface.

S Heatwell offers band heaters in different sizes. There are flexible, inexpensive & reliable. These can be insulated heaters made out of nickel chrome resistance ribbon precisely wound On specially selected mica or micanite sheet . It is then insulated metal sheeting and rolled to the required diameter. Best quality of raw materials are being used & heater life is long. These are very simple to fit with their integral champing arrangements.

We can also design according to client requirements.

Specification

• High Quality
• Long life span
• Good conductor

Short Wave IR emitters are suitable for all applications in which the attainment of high temperatures in the shortest possible time is what counts. Short wave quartz infrared heaters/ Lamps are used in various industrial applications. It contains tungsten filament, helically wound, encased in quartz envelope. Tungsten as resistive element is capable of generating temperature in excess of 2750 C

Advantages

• Heating is done by radiation, this eliminates loss of energy used for heating media and heat loss due to convection
• Here the infrared waves penetrate the material, on which it falls and delivers the heat directly to that material
