Extrusion Heating
Uniform Barrel and Die Heating for Consistent Extrusion
Plastic and rubber extrusion requires precise, zone-by-zone barrel heating to control melt viscosity, throughput, and product quality. Sri Ambika ceramic band heaters and coil heaters are engineered for the continuous high-temperature demands of single-screw, twin-screw, and co-extrusion lines — from feed zone to die.
Heating Problems
We Solve
Non-uniform melt temperature causing inconsistent product dimensions
Slow barrel heat-up adding to machine downtime between product changes
Hot zone dead-spots reducing product quality in multi-zone extrusion
Early band heater failure under continuous thermal cycling
Custom barrel diameters requiring non-standard heater sizes
Key Engineering
Considerations
Zone-by-zone wattage calculation based on barrel diameter and target temperature
Ceramic vs mica insulation selection based on maximum process temperature
Two-part or three-part band assembly for large barrel diameters
Coil heater specification for nozzle zones based on output and bore diameter
Thermocouple integration for closed-loop zone temperature control
