Core Value
The 500W Industrial Hot Runner Nozzle Coil Heaters with Metallic Braided Lead Wires is engineered for high-density, precise thermal management in demanding plastic injection molding nozzles, hot runner manifolds, and die systems. Built with a high-purity compacted MgO insulation core encased in a premium stainless steel sheath, this industrial coil heater features heavy-duty Metallic Braided Lead Wires.
The flexible metal armor sleeve provides superior mechanical protection for both power and integrated thermocouple leads, guarding against wire crushing, sharp mold plate edges, high flexure stress, and plastic melt contamination.
Operating continuously at temperatures up to 650°C (1202°F), it delivers 360° uniform thermal distribution, rapid heat recovery, and exceptional PID temperature stability to eliminate nozzle freezing and resin degradation. BACKED BY 30+ YEARS MANUFACTURING EXPERIENCE and UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS for continuous, maintenance-free industrial operation.

Installation & Integration Guidelines
-
Nozzle Mating Surface Cleaning: Clean the nozzle surface thoroughly to remove carbonized plastic, oil, and debris prior to mounting 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 cracking internal MgO insulation.
-
Metallic Braided Wire Routing: Route the metallic braided leads through mold wire channels. Secure wires with clamping plates to prevent sharp 90° bends or pinching under mold plates.
-
Thermocouple Wiring (If Equipped): Connect thermocouple leads using correct color polarity (For Type J: White = Positive, Red = Negative) directly to your PID controller.
-
Pre-Heating Bake-Out: Perform a low-voltage pre-heating cycle at 100°C for 10 minutes to clear ambient moisture absorbed during storage prior to ramping up to full operational voltage.
