FEATURES :-   Plastics Extrusion Machinery Hot Melt-Glue Pots Blown Film Dies Runnerless Molding-Plastics Textile Industry Commercial Food Service Hot Stamp and Die Heating   Description   The liquid cooling function of the Cast Band Heater is of primary importance in maintaining the proper temperature of the barrel in the extrusion process. This Heater can be manufactured in STRIP TYPE & BAND TYPE . In Band type it comes with Water Cooling system & without Water cooling system. All Aluminium Cast heaters are customized. The Tubular Heating element is embedded in the Aluminium cast & machining is to be done to get the required size. High Thermal Conductivity provides uniform temperature. The main application of these heaters are in the Extruders .

FEATURES :-   Jalak Electrical’s nozzle band heaters “COIL TYPE” are capable of performance under the most adverse conditions. Highly recommended for processing high temperature resins to eliminate premature failures due to burn out/ process material leakage. Heat transfer is based on conduction as well as on radiation principle, which not only improves the thermal efficiency but easy to assemble on nozzles as no pressure on heating surface is essential. Even unskilled operator can fit the heater with no risk of failure of the heater. Coil Type Nozzle Heaters are specially designed to prevent the failures of heaters against the leakage and contamination of plastic material at nozzle position. This heater can meet the higher temperature requirement prior to moulding at nozzle position.     SPECIFICATIONS :-

FEATURES :-   Custom-formed to meet specific requirements Precision wound resistance wire for long heater life Superior heat transfer. Variety of lengths available Easy to install Durable Even Heat Distribution   Description   Jalak Electrical’s Finned tubular heater are the most common type of heating elements used for heating air and other gases. The fins along the tubular length assist in even heat dissipation. All elements have mild steel fins copper brazed to the tubular heating element sheath unless otherwise specified. Duct heaters use fin tubular elements within its design to help reduce the watt density. It also allows for more consistent air flow streams within the duct and increases the life longevity of the elements

FEATURES :-   Ceramic end cap protects the cartridge internally from outside contamination. Resistance wire and lead wires are mechanically spliced with heavy wall nickle connectors for positive electrical connection. Nickel-Chrome resistance wire is precisely wound on a high purity magnesium oxide core,  placing the resistance wire as close to inside of the sheath as possible while maintaining dielectric strength. This provides excellent heat transfer,  and results in the highest possible watt densities and longer heat life.  Here Ally-321 stainless steel is used to provide high temperature strength,  good conductivity and resistance to oxidation up to 700 degree centigrade.  In manufacturing process Magnesium Oxide(MgO) is used to fill all remaining space inside the ceramic insulator,  thus increasing thermal conductivity,  dielectric strength and heater life. Ceramic end cap and swaged-in Lava plug protect the internal cartridge from outer contamination.      SPECIFICATIONS :-     Voltage 240 (Or consult J.E. for specific application.)   Maximum Temperature 700 Degree Centigrade Maximum Watt Density : 100 to 120 Watt/square inch     TOLERANCE DIMENSIONAL :-   Actual Diameter inches +0.50 to -0.50(Above dia 16mm) +0.80 to -0.80(Above dia 20mm)   Resistance Tolerance +10% to -5%   Wattage Tolerance +5% to -10%
