Hot-Melt Road Marking Paint Production Line

Compact mixing and bagging system for dry hot-melt road marking paint

Tongding offers a compact production line designed to process powders, granules, resins, fillers, and premixed glass beads into dry hot-melt road marking paint.

This production line integrates raw material feeding, conveying, low-shear mixing, finished product buffering, weighing, bagging, and sealing into a practical, unified system.

Raw Materials

Depending on the formulation, the line can process a variety of dry powders and granular materials, such as:

• C5 petroleum resin
• EVA (Ethylene-Vinyl Acetate copolymer)
• PE wax (Polyethylene wax)
• Rutile titanium dioxide (TiO₂)
• Calcium carbonate
• Quartz sand
• Premixed glass beads
• Other dry additives

The final equipment configuration is determined based on the customer's formulation, material characteristics, and required production capacity.

Production Process

Simplified Process Flow

The compact layout can be adjusted to suit existing factory space and the customer's desired level of automation.

Key Equipment

Manual palletizing can be retained if automatic palletizing is not required.

Mixer Key Considerations

25 kg Bagging System

The finished mixture is discharged into a buffer hopper prior to packaging.

Typical configuration includes:

• 25 kg net weight bagging machine
• Bag conveyor
• Automatic bag sewing
• Thread cutting
• Manual palletizing

Packaging accuracy and speed depend on the selected bagging machine and material characteristics.

Compact Production Line Configuration

A compact thermoplastic road marking paint production line does not necessarily require a full suite of large-scale processing equipment.

Depending on the raw materials used, the basic configuration may omit the following equipment:

• Raw material silos
• Sand dryer
• Crusher / pulverizer
• Heating system
• Cooling system
• Liquid metering and dosing system
• Automatic bag placer
• Automatic palletizer

This allows the production line to focus on the core process flow:

Additional equipment can be quoted separately if the formulation or production process has specific requirements.

Production Capacity & Project Configuration

For compact projects, the typical configuration parameters are as follows:

• Actual batch size
• Target output
• 25 kg finished product bags
• Manual feeding
• Semi-automated production
• Manual palletizing

Actual output depends on mixing time, feeding time, discharge time, packaging speed, formulation, and operating conditions. Therefore, the final production capacity should be confirmed based on the complete production cycle.

Dust Collection & Electrical Control

Dust collection systems can be installed at key dust-generating points, covering the following stages:

• Manual feeding
• Mixer charging
• Material conveying
• Bagging

The control system can integrate major production equipment, sensors, weighing systems, and safety control devices. Electrical specifications are configured according to target market requirements (e.g., 415 V / 50 Hz / 3-phase).

Specific brands and specifications for electrical components can be selected based on requirements in the technical quotation.

Engineering Support

Tongding can supply the main equipment as an integrated production line rather than as separate machines.

Project support can include:

• Process configuration
• Equipment selection
• Production-line layout
• Equipment manufacturing
• Electrical integration
• Installation and commissioning support
• Operator training
• Technical documentation
• Spare-parts recommendations

For project-based orders, the equipment scope and technical requirements are confirmed before manufacturing.
