Injection Moulding
Precision Heating Across Every Zone of the Injection Moulding Process
Injection moulding machines demand precision heating at multiple points — the plasticising barrel, injection nozzle, hot runner manifold, and the mould itself. Sri Ambika supplies a complete range of ceramic band heaters, nozzle heaters, hot runner coil heaters, and cartridge heaters for OEM machine builders and processors across the injection moulding industry.
Heating Problems
We Solve
Temperature non-uniformity across the injection barrel zones
Gate freeze-off or stringing from incorrect nozzle temperature
Hot runner manifold cold spots causing part defects
Mould surface temperature non-uniformity affecting part quality
Short heater life due to rapid thermal cycling
Key Engineering
Considerations
Ceramic band heater selection based on barrel diameter, material, and wattage
Nozzle heater bore and wattage sizing to match nozzle geometry
Coil heater specification — diameter, pitch, and thermocouple integration
Cartridge heater specification for mould heater bores (diameter tolerance ±0.01mm)
Temperature sensor integration (J/K thermocouple or PT100 RTD)
