Thermoplastic preheaters are specialized road marking devices used to melt thermoplastic coatings. They utilize liquefied petroleum gas for heating and uniform mixing, offering energy efficiency, safety, and high performance. They are primarily used for marking materials for highways, parking lots, and urban streets. YG offers a variety of mechanical and hydraulic specifications in various capacities. This article will explore two series of high-performance thermoplastic melting equipment—the mechanical series and the hydraulic series. By understanding their specifications, advantages, and working principles, you will be better able to select the ideal machine for your specific needs.

Advantages Of YG Company’s Hot Melt Kettle
Investing in a high-quality thermoplastic preheater offers several distinct advantages that directly impact your bottom line.
- Mechanical single/double cylinder: Compact size, accessible to underground parking lots.
- Hydraulic double cylinder: High efficiency, capable of forward and reverse stirring for uniform heating, and can supply two road marking machines simultaneously.
- Durability and material quality set these machines apart. Both series use stainless steel tanks and high-carbon steel bottoms, ensuring resistance to corrosion and wear. The vertical paddle mixers provide thorough and uniform mixing, preventing material separation and ensuring a consistent application.
- Safety features are integrated into every model. The mechanical series includes an automatic protection device that disengages the engine and reducer during emergencies. The hydraulic series is equipped with an overload relief valve, protecting both the operator and the machine from damage caused by improper use.
How A Thermoplastic Melter Works?
The working principle of a thermoplastic preheater is straightforward yet highly effective. The operator loads solid thermoplastic material into the kettle. The LPG burner heats the tank from below, while the vertical paddle mixer continuously rotates to ensure even heat distribution and prevent scorching. Once the material reaches the optimal application temperature—typically between 180°C and 220°C—it is ready for use. In mechanical models, the manual clutch controls the mixing action. In hydraulic models, the hydraulic system provides smoother, more consistent power to the mixing mechanism. The result is a steady supply of high-quality molten thermoplastic ready for road marking applications.
Application Scope & Selection Advice For Melting Equipment
These thermoplastic melting machines are designed to handle a wide range of thermoplastic marking materials, including standard road marking paints, reflective beads, and anti-skid additives. The uniform heating and mixing capabilities ensure that additives are evenly distributed, resulting in durable, high-visibility markings.
If you are looking for a reliable thermoplastic preheater to enhance your road marking operations, YG offers a comprehensive lineup of both mechanical and hydraulic models to match your project scale and budget. Our equipment is built for durability, safety, and efficiency, ensuring that you can deliver professional results day after day.
In addition to these, YG also offers other road machinery, such as small road rollers. Please feel free to contact us if needed.
Frequently Asked Questions About Thermoplastic Preheater
A: Essential safety features should include automatic over-temperature cutoff, sturdy lid mechanisms, and stability or tilt switches that shut off heat if the unit is moved. Ensure the machine carries relevant international certifications (like CE) confirming it meets safety, health, and environmental protection standards for your region.
A: Not all preheaters are suited for all materials. If you use specialized mixes, confirm that the thermoplastic melting pot’s agitator system and inner liner are compatible. Some abrasive or chemically modified materials may require a specific, more resistant liner material.
