In road marking construction, a thermoplastic preheater is an essential piece of equipment used to heat thermoplastic paint to the proper temperature and stir it evenly before application. Whether it’s a highway, parking lot, or urban road, choosing the right hot melt kettle can significantly improve construction efficiency and ensure the adhesion and durability of the markings.

Thermoplastic road marking paint needs to be heated to 150–180°C before application to achieve optimal flow and adhesion. A quality thermoplastic boiler not only heats quickly but also ensures even heating and high fuel efficiency. Insufficient heating or uneven stirring can easily cause uneven lines, reduced durability, and even rework—adding to project costs.
Mechanical Single/Double-Cylinder Hot Melt Kettle (YG300/600)

The YG300 and YG600 are mechanically driven thermoplastic premelter models, compact in size and easy to operate—ideal for small to medium road marking projects. Powered by a diesel engine, they can handle 600–800㎡ per day. A unique advantage is their compact body, allowing entry into underground parking garages, a rare feature in similar products.

Suitable for factories, parking lots, residential areas, and other medium-scale projects
Hydraulic Double-Cylinder Hot Melt Kettle (YG800/1000/1200)
For larger road marking projects, the hydraulic thermoplastic boiler is more efficient. YG800, YG1000, and YG1200 models feature a 15HP electric-start diesel engine driving a hydraulic system, allowing forward and reverse stirring for more even heating. They can produce up to 2000㎡ per day and supply two road marking machines simultaneously.

Key Advantages:
High efficiency, can feed two marking machines at once
Forward and reverse stirring for more uniform heating
Large capacity for long, continuous operation
Fast preheating: first kettle ready in 20 minutes, second in 7–8 minutes
When selecting a thermoplastic preheater, consider:
Project size: Mechanical type for small/medium projects; hydraulic type for large-scale road construction
Work environment: Mechanical type is smaller and better for confined spaces
Production needs: Hydraulic type offers higher efficiency for intensive operations
Whether choosing a mechanical or hydraulic thermoplastic premelter, a high-quality machine will greatly improve efficiency, reduce fuel costs, and ensure the durability and visibility of road markings. Selecting the right model for your project ensures every line is long-lasting and sharply defined.
