Thermoplastic paint pre-heater, also called hot melt kettle, is used for heating, melting, and stirring thermoplastic marking paints continuously, preparing hot melt paints for the thermoplastic machine during long distance road lines marking work.

Road paint pre-heater, always matched with thermoplastic machine, is main equipment for thermoplastic paint lines marking construction.
During the construction, first, put powder coating (additives) into the hot-melt kettle. The heating temperature must be controlled between 180 ℃ ~ 210 ℃.
Keep stirring while melting, until the paint into a homogeneous liquid state.
And then, the hot-melt material is ready to be discharged into the thermoplastic machine for marking construction.
The melting paint quality affects directly to the traffic lines marking quality, so the pre-heater is a key part during thermoplastic paint road lines construction, and essential device for thermoplastic paints heating and melting.

Dayu brand thermoplastic paint pre-heaters (double-cylinder and single-cylinder) are hydraulic stirring preheater. Use diesel engines as power, driving hydraulic devices, the hydraulic motor and stirrer. The integrated direction shift valve makes the mixer positive-negative two-way stirring. LGP gas stove is heating directly from bottom, melting paints for the paint tank of thermoplastic road marking machine.
