Precision Heating for Plastics Processing
The plastics processing industry demands heating elements that deliver consistent temperatures, rapid heat-up, and long service life under continuous production cycles. Sri Ambika manufactures ceramic band heaters, cartridge heaters, and hot runner coil heaters engineered specifically for the high-throughput demands of plastic machine builders and processors across India.
Heating Challenges
Maintaining uniform barrel temperature for consistent melt quality
Rapid heat-up to reduce machine downtime between runs
Hot runner nozzle temperature precision to prevent gate freeze-off or drool
High-frequency on/off cycling causing premature element failure
Custom barrel diameters requiring non-standard band heater sizes
How We Address Them
Ceramic band heaters for barrel zones (40mm–1200mm diameter, up to 650°C)
Mica band heaters for lower-temperature barrel sections (up to 260°C)
Nozzle heaters for injection nozzle gate zones
Coil heaters for hot runner manifold and nozzle zones
High-density cartridge heaters for dies and platens
Strip heaters for flat mould heating surfaces
Recommended Heating Elements
Frequently Asked Questions
Q1What is the maximum temperature for ceramic band heaters?
Our ceramic band heaters operate up to 650°C, making them suitable for all standard engineering plastics including PEEK and PPS.
Q2Can you manufacture band heaters for non-standard barrel diameters?
Yes. We manufacture custom band heaters for any barrel diameter from 40mm to 1200mm. We require the outer diameter, width, and wattage specification.
Q3What is the lead time for OEM band heater orders?
Standard sizes are available from stock. Custom-manufactured band heaters have a lead time of 5–10 working days depending on quantity and complexity.
