Automation And Unmanned Operation Upgrade Of Hot Melt Glue Production Line

With the continued growth in global demand for high-performance hot melt glue, traditional manual hot melt glue factories are facing problems such as insufficient production capacity, rising labor costs, unstable quality, and high safety risks. Automated and unmanned production lines have therefore become a key direction for industry upgrading.

Why must hot melt glue production line become automated?

1. Addressing the high risks of manual feeding

Hot melt glue raw materials (EVA, TPR, SIS, petroleum resin) are mostly powders, granules, or hot melt. Manual feeding easily leads to:

• Scalding and dust inhalation
• Formula weighing errors
• Low manual efficiency

Automated systems can achieve automatic metering, automatic feeding, and remote monitoring.

2. Strong demand for capacity growth

Traditional production line: 8-10 workers/1 line

Automated production line: 2-3 workers/1 line

Capacity can be increased by 30%-120%, and batch quality is more stable.

3. Higher efficiency required for finished product molding

Molding systems for block, granular, and film-like hot melt glue are rapidly becoming widespread:

• Automatic cutting
• Automatic cooling tunnels
• Automatic weighing
• Automatic packaging

Reduced human intervention and product contamination.

4. International customers demand higher standards

Customers are increasingly emphasizing:

• Clean factories
• Automated packaging
• MES data management

Automation has become a standard requirement for export production lines.

What systems are included in the automation upgrade of hot melt glue production line?

1. Automated feeding system

• Pneumatic conveying system
• Vacuum feeder
• Robotic arm feeding system
• Automatic weighing system

Accurate feeding, reduced manual labor requirements, and improved formula consistency.

2. Automatic stirring and mixing system

Suitable for reactors and sigma mixers:

• Automatic temperature control
• Automatic speed regulation
• Automatic discharge system
• PLC+touch screen fully automatic control

Ensures uniform mixing and automatically records batch data.

3. Automated molding system

Equipped with automatic molds, cooling tunnels, cutting machines, and automatic weighing and packaging machines.

4. Automated packaging system

• Automatic weighing
• Automatic bagging/drum filling
• Automatic sealing
• Automatic palletizing
• Automatic labeling

Reduces manual labor and improves packaging consistency.

5. MES intelligent production management system

• Production data acquisition
• Batch traceability
• Equipment operation status monitoring
• Remote diagnostics
• Alarm recording

Transforming factories from "labor-intensive" to "digital factories".

Is it necassary to go all-in on fully automated systems?

NO!

✔ Start with manual feeding → upgrade to an automated feeding system later.

✔ Start with semi-automatic packaging → upgrade to an automated packaging line later.

✔ Modular equipment upgrades prevent wasting the original investment.
