Core Value
The 220V Stainless Steel Hot Runner Heater (Model: HT-CLW-450) is engineered for high-efficiency thermal profile management in demanding plastic injection molding nozzles, hot runner manifolds, and precision die systems. Built with a high-density compacted MgO heating core encased in a premium SS304/SS316 sheath, the HT-CLW-450 features an advanced Silicone Glass Fiber Sleeving over its terminal leads. This specialized insulation sleeve provides exceptional dielectric strength, heat resistance, and extreme flexibility, protecting lead wires from mechanical abrasion, oil contamination, and plastic melt splashing. Operating continuously at temperatures up to 650°C (1202°F), it delivers uniform 360° heat distribution, rapid warm-up, and precise temperature stability to prevent 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 Surface Cleaning: Clean the nozzle mating surface thoroughly to remove carbonized resin, oil, and debris before installing the HT-CLW-450 heater
-
Smooth Slide Fitting: Slide or expand the heater onto the nozzle smoothly. Do not force or strike the element with hard metal tools to avoid cracking internal MgO insulation.
-
Silicone Lead Wire Routing: Route the silicone glass fiber insulated leads through the mold wiring channels. Avoid sharp 90° bends or pinching under clamping plates.
-
Thermocouple Wiring (If Equipped): Connect thermocouple wires using correct polarity (Type J: White = Positive, Red = Negative) to dedicated PID controller terminals.
-
Pre-Heating Bake-Out: Perform a low-voltage pre-heating cycle at 100°C for 10 minutes to clear any ambient moisture absorbed during storage prior to ramping up to full 220V power.
