PTC heaters are self-regulating ceramic elements. When powered on, they heat up quickly, melting the glue stick. As the temperature rises, their resistance increases automatically, reducing current flow to maintain a stable, optimal temperature.
Key Benefits:
- Fast heat-up
- Stable glue temperature
- Energy-efficient
- Safe and prevents overheating
How PTC Heaters Work?
- When the glue gun is switched on, electricity flows through the PTC ceramic element. At a low temperature, the element has low resistance, allowing high current to flow and producing rapid heat.
- The heat is transferred to the glue stick, melting it quickly and preparing it for dispensing.
- As the PTC element reaches its designed operating temperature, its resistance increases significantly, automatically reducing current flow. This stabilizes the heating level and prevents overheating.
- During use, the PTC heater cycles between heating and regulating, keeping the glue at the optimal temperature for consistent flow without burning or carbonizing.
