Core Value
The 220V Stainless Steel Hot Runner Coil Heater with Braided Thermocouple Wire is designed for high-density, precise thermal management in demanding plastic injection molding nozzles, hot runner manifolds, and packaging equipment. Featuring a compacted MgO insulation core wrapped in a premium stainless steel sheath, this heater incorporates an integrated Type J or Type K thermocouple shielded by heavy-duty Metal Braided Armor Wire.
This rugged wire construction protects both power leads and sensor wiring against mechanical crushing, sharp mold edges, and continuous machine vibration. Capable of operating continuously at temperatures up to 650°C (1202°F), it delivers 360° uniform thermal distribution, rapid warm-up, and real-time closed-loop PID feedback to eliminate gate freeze-off and polymer degradation. BACKED BY 30+ YEARS MANUFACTURING EXPERIENCE and UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS for continuous, maintenance-free operation.

Installation & Integration Guidelines
- Nozzle Surface Cleaning: Thoroughly clean the nozzle mating surface to remove carbonized plastic, oil, and debris prior to installing the coil heater.
- Smooth Slide Fitting: Gently slide or expand the coiled heater onto the nozzle body. Never strike the element with a metal hammer to prevent damaging internal MgO insulation.
- Braided Wire Routing: Route the braided thermocouple and power wires through mold wire channels. Secure wires with clamping plates to prevent strain during mold cycling.
- Thermocouple Polarity: Connect thermocouple leads using correct color polarity (For Type J: White = Positive, Red = Negative) to your PID controller.
- Initial Bake-Out Cycle: Run a low-voltage pre-heating cycle at 100°C – 120°C for 10 minutes to eliminate ambient moisture absorbed by insulation before ramping up to full 220V power.
