How To Improve The Production Rate Of Hot Melt Glue?

Equipment level: Improve mixing, melting and cooling efficiency

Choose high-efficiency mixing equipment

• Sigma mixer: Provides powerful shear and kneading forces, achieving 30-50% higher mixing efficiency than conventional stirred tanks.
• Optimized blade structure: ∑-shaped blade can be customized based on material viscosity, improving mixing uniformity and reducing dead spots.
• Vacuum degassing: Degassing while stirring shortens mixing time and improves product quality.

Improve heating efficiency

• Use thermal oil circulation heating system or electric heating jacket with a temperature control module to achieve rapid and uniform heating.
• Use high thermal conductivity material (such as SS304/316 with polished interior) to reduce energy loss.

Optimized discharging and pelletzing equipment

• Continuous extrusion pelletizing systems replace intermittent discharging, enabling continuous production.
• Underwater pelletizing or cooling belt+pelletizer combination provides fast cooling and stable pelletizing.
• Automated cutting systems reduce manual intervention.

Process level: Optimize formula and production process

1. Pre-melt or pre-mix some raw materials: Pre-melting or pre-mixing wax or resin components can reduce the main kettle heating and mixing time.
2. Optimize the addition sequence: Adjusting the addition sequence based on the melting points and compatibility of the materials can avoid repeated heating and shorten the reaction time.
3. Control material viscosity: High viscosity can reduce mixing and pumping speeds. Adjust the resin ratio or add a flow improver.
4. Switching to continuous production process: Traditional batch production is inefficient, so modern hot melt glue factory is moving towards:
   • Continuous feeding+continuous extrusion
   • Dynamic mixing+online filtration+online pelletizing

Raw material level: Choose an easy-to-process system

• Select low-melting-point, high-flow resins (such as EVA, APAO and TPR).
• Control filler and additive particle size to reduce agglomeration and improve mixing fluidity.
• Use low-volatility raw materials to reduce vacuum pumping and degassing time.

Automation and intellignet control

PLC+touchscreen automation control system

• Automatically controls temperature, mixing speed, feed rate and discharge speed.
• Can store recipe parameters for quick product switching.
• Precise temperature control reduces manual intervention, improving stability and dafety.

Robotic automatic feeding system

• Enables continuous and precise addition of raw materials, eliminating manual interruptions.
• Improves feeding accuracy and speed.
• Reduces dust and human contact, improving environmental safety.

Production line informationization

• Real-time monitoring of output, energy consumption, and equipment operating status enables production data analysis and efficiency optimization.
