Installation & Integration Guidelines
- Nozzle Installation: Clean nozzle bore thoroughly (12mm ±0.05mm). Slide heater onto nozzle with proper fit (snug but not tight). Thermal paste improves contact but optional. Position heater to cover melt channel. Ensure leads exit away from hot runner plate. Maintain 3mm clearance from mold plates. Avoid lead contact with sharp edges.
- Electrical Connection: 240V or specified voltage supply. Use high-temperature terminal lugs. Fiberglass leads rated 300°C – route away from hot surfaces. Strain relief mandatory to prevent lead fatigue. Dedicated 5A circuit per heater. Ground connection mandatory for personnel safety.
- Temperature Control: J-type thermocouple recommended for precision control. Place thermocouple in nozzle tip or body. PID controller for fast response and stability. Solid-state relay (SSR) switching recommended. Current limiting for soft start to extend heater life. Set ramp rate to 150°C/min maximum.
- Safety Systems: Over-temperature limit controller (backup protection). Ground fault monitoring for personnel safety. Heater burnout detection alarm system. Protective guarding to prevent accidental contact. Lockout/tagout procedures for mold maintenance. Regular inspection of heater and lead condition.
