Hot Glue Gun Heater
A glue gun has to hit melt temperature fast and hold it steady through repeated use, all inside a barrel with barely enough room for the heating element itself.
There’s no room in a glue gun barrel for a separate thermostat assembly — the heating element itself has to be the whole safety and control system.
Why a bare PTC chip fits this application
A hot glue gun needs to reach adhesive melt temperature quickly, hold it steady through intermittent use, and fit inside a compact handheld barrel. A bare PTC heating chip does all three: full current flow while cold gets the barrel to temperature fast, the self-limiting Curie point holds a stable melt temperature without a separate thermostat, and the small chip footprint fits the tight space constraints of a glue gun barrel.
Compact heating chip for handheld tools
Bare ceramic element with a lead-wire configuration sized to fit inside compact tool barrels — no separate housing or thermostat needed.

- Faster time-to-melt than a fixed-resistance coil of similar size.
- No thermostat cycling — output throttles smoothly as the element approaches its Curie point.
- Consistent melt temperature over the tool’s lifetime, without coil degradation drift.
This is the same compact-element principle behind PTC heaters in hair styling tools and curling irons. PTCWORKS supplies heating chips to handheld-tool OEMs — contact our team with your target melt temperature and barrel dimensions.
