"Sunil Heat" brand band heaters are made of nickel chrome resistance ribbon precisely wound on specially selected Mica or Micanite Sheet it is then insulated in metal sheating and rolled to the required diameter. Mica insulated band heaters are specially used to heat the cylinders on all types of plastic machinery. Band heaters can be made in two halves & customised thermocoulpe holes.
Uses:Plastic injection & Blow moulding machines extrusion barrels, cylenders, pipes drums etc. Band heater is a conveniently shaped element for both round & square surface easly installed with standard hardware.
SUNIL HEAThas designed sealed mica nozzle band heater to prevent the failure of nozzle heaters against the leakage & contamination of plastic material at nozzle position. These heaters meet the required temperature prior to molding at nozzle position. These heaters are hermetically sealed during the manufacturing process. The connection between the heating element & the leads is protected by a special terminal cap made of brass 1mm thick. The terminal cap is brazed which allows a high mechanical strength in the most delicate area of the heater i.e. the termination. The heating of nozzle in injection machines is still a big problem owing to subsequent stops of the production process and cost incident. We have seen a large series of cases causing an early failure most of them are due to plastic leakage impregnating the heater and causing heater failure. These problems are solved by using our sealed mica nozzle band heaters. There can be custom built entry points for termination considering customers requirement, alternative tubular nozzle heaters are available.
SUNIL HEATSNozzle band heater3are basically a mica insulated band heater. These are mechanically sturdy. These heaters are made out of brass & Stainless steel sheath .These nozzle band heaters are usually employed when there is a limited space around the nozzle. An excellent coupling between the heating element & the nozzle provides the maximum heating efficiency. These heaters are fitted to the nozzles of injection molding machines.

SUNIL HEATSAir cooled ceramic band heaters are designed for super efficient & economical cooling on extrusion and blow molding machines. These heaters are band ceramic heaters manufactured by perforated metal steel. These heaters are 60% open for maximum surface exposure for better cooling. These heaters are covered with blower jacket for mounting with blower. The advantages of these heaters are lower cost, easy replacement and uniform temperature control.
1. Maximum watt density = 60 watts/Sq.inch.
2. By use of higher temperature, faster off sequence is possible
3. Use of special ceramic material (Steatite) high thermal conductivity is obtained.
4. The heaters are fabricated with heavy gauge of stainless steel perforated sheath. The heating coils (80/20 nichrome wire) inserted in the holes of steatite ceramic insulators, the protective junction box with Teflon insulated lead wires, the spot welded clamping provides a uniform claiming force. This rugged construction results in longer heater life.
5. For the blower air cooling process. Application, the perforated ceramic heater can be manufactured as per your specification.
SUNIL HEAThas specifically designed and engineered insulated band ceramic heater to meet the ever increasing demand for energy (power) conservation and improving heating operation efficiently. These heaters are capable of generating higher operating temperatures up to 500 c.
These are ceramic insulated band heaters, its superior designed is to save the power it is constructed with 1 thick cerawool insulating blanket from the outer surface increasing the overall diameter by 2 . It reduces power consumption up to 30% . The external surface temperature of the insulated ceramic band heater is approx 80c while running inside surface temperature is 300 c . First is the heaters built in insulation & second is the cerawool insulation the heat transfer in the ceramic heater is by convection and radiation. The heat dissipation from the heaters will be prevented by its insulation on the outer surface. This process of heat exchange will make a uniform layer of heat all over the barrel resulting into swift development of temperature. There will be quick response to temperature controller & it will have more off cycles at maintained set temperature resulting in saving of electric power.
Saving In Energy Up to 30%, 0 Uniform Heating. Reduced Preheating Time Of Machine. 0 Cool Working Atmospheres for Operator.

| D shape elements are heating elements formed from round to D section and then formed to round diameter to achieve a cylindrical format. They are compacted to a much extreme density. This process increases both heat transfer ability and insulative value to the di-electric. The greater insulation value accommodates higher watt densities. These heaters produce inpre wattages compared to conventional heaters and can operate at higher temperatures. Maximum Operating Temperature - 65OC Speciality Longer Service Life: The life of D shape elements is directly related to its internal operating temperature. Denser and more uniform compaction of the di-electric provides greater heat transfer to the sheath. This combined with more efficient heat transfer to the surrounding metal through intimate contact with the wall of the bore. This Dermits the D section elements to run substantially cooler resulting Into a better life. Better heat transfer means less power consumption to maintain the set point temperature reducing operating costs. Features

Super High Temperture Black Infrared HeatersSuper high temperature heaters were developed to increase the previous maximum possible surface rating of ceramic panel radiators from 64 kw/m2 to 77 kw/m2.
This radiators, produced using the hollow casting ceramic process, are filled with thermal insulation material and have a special black gaze and a gold-plated back. At an operating temperature of 900c, over 75% of the electrical energy supplied is transferred to the material to be heated as medium to long-wave IR radiation.
This series radiators are therefore particularly suitable for use in plant construction in which special solution have to be drawn up for the customer's specific needs and for applications requiring high outputs.
The four designs cover the power range from 300 W to 1200 W and have customary market dimensions. Existing IR equipment can therefore be retrofitted with this series radiators.
This is a special type of infrared heater with color-changing feature. Along with a change is temperature the heater changes its color. This is helpful to the users in a sense that there is a visible indication of the level of temperature reached at any given point of time.
Where there are large IR Heating Panels with hundreds of heaters installed, it is possible and very easy to determine the non-working heaters just by looking at the color of each heater.
This thereby helps in quick & easy replacement of the faulty heater
