Hot Melt Glue Production Line: A One-stop Solution From Raw Materials To Finished Products

Hot melt glue is widely used in industries such as packaging, electronics, automotive, construction, and disposable hygiene products due to their ease of use, strong adhesion, and rapid curing. For companies looking to establish an efficient production system, a complete hot melt glue production line not only determines production capacity but also affects product quality and production stability.

1. Raw Material Preparation and Pretreatment

High-quality raw materials are fundamental to hot melt glue production.

• Resin: Provides adhesion and hot melt properties, such as EVA and styrene copolymers.
• Wax: Improves the flowability and open-circuit viscosity of the hot melt glue.
• Additives: Antioxidants, tackifiers, light stabilizers, etc.

In the hot melt glue production line, raw materials must be accurately weighed adn premixed to ensure stable proportions, providing a uniform material base for subsequent kneading and extrusion.

2. Kneading and Melting

Main equipment includes reactor or sigma mixer, whose functions are:

• To thoroughly mix high-viscosity raw materials, ensuring uniform dispersion of resins, waxes, and additives.
• To rapidly melt the materials using a heating system, forming a homogeneous liquid.
• To eliminate air bubbles under vacuum conditions, improving product density and stability.

JCT's mixing equipment can be customized with impeller structures, heating methods, and discharge systems according to material characteristics, achieving high-efficiency production and easy cleaning and maintenance.

3. Extrusion and Granulation

Hot melt glue, after kneading and melting, needs to be shaped using an extruder or granulation system:

• Underwater granulation: Suitable for granular hot melt glue, producing uniform output, rapid cooling, and a smooth surface.
• Aquatic granulation/strip cutting: Suitable for producing block or strip-shaped hot melt glue for various packaging and application needs.

Equipment selection directly affects finished product specifications, production capacity, and packaging efficiency, making it a crucial aspect of production line design.

4. Cooling, Drying and Packaging

• Cooling system: Rapidly cools the granules using water or air cooling to ensure granule hardness and storage stability.
• Drying system: Removes surface moisture to prevent sticking.
• Packagign system: Optional automatic or semi-automatic packaging machines ensur easy transportation and sales of the finished product.

The entire hot melt glue production line can be fully or semi-automated, reducing manual intervention and improving safety and production efficiency.
