We are offering ceramic band heaters

description:
comheaterss band ceramic heaters are developed to meet industrial heating requirements for high temperature which calls for ever-increasing process temperature. Band ceramic heaters are made of helically wound 8020 nichrome wire evenly stretched and precisely strung through a specially designed steatite ceramic bricks forming a flexible heating mat. It is then placed in flexible stainless steel housing with cerawool insulation. These heaters are flexible & can be fitted easily.

It is then placed in flexible stainless steel housing with cerawool insulation. These heaters are flexible & can be fitted easily.

advantages:

specially to heat the cylinders on all types of plastic processing machinery.
maximum watt density = 50 wattssq.inch in comparison to mica band heaters.
by the use of higher temperature a faster off sequence is possible. Use of special steatite ceramic material provides very good utilization & transfer of heat.
particularly suited to heat the cylinder on all types of plastic machinery, working temperature up to 500 celsius (sheath temperature 800 celsius).
the heaters are fabricated with heavy gauge of stainless steel sheath, built in insulation. The heating coils (8020 nichrome wire) inserted in the holes of steatite ceramic insulators, the spot welded clamping provides a uniform clamping force. This rugged construction results in longer heater life. Elements are bypassed at thermocouple holes.

We are offering 30% power saving mica band heaters
description
"comheaters" 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.

Mica Nozzle Band Heater

Description:

COMHEATERS Nozzle 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.
Technical Features:

Wattage up to 7wcm2.
Maximum working temperature 360 Celsius.
Our specialty is minimum diameter 10 mm.
Minimum width should be 25mm.
Standard voltage 230V110V.
Standard lead length 1 Meter long.
Also available with built in ungrounded JK typ

We offer Perforated Band Ceramic Heater.
Description:
COMHEATERS Air 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.

Working Principle:-

Maximum watt density = 60 wattsSq.inch.
By use of higher temperature, faster off sequence is possible
Use of special ceramic material (Steatite) high thermal conductivity is obtained.
The heaters are fabricated with heavy gauge of stainless steel perforated sheath. The heating coils (8020 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.
For the blower air cooling process. Application, the perforated ceramic heater can be manufactured as per your specification.

We are offering ceramic heater.
Description:
comheater has 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.

working principle:
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.

We are offering sealted nozzle band heater

description:
comheaters has 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.
