EVA Hot Melt Glue Production Line

JCT Machinery designs and manufactures complete EVA hot melt glue production lines for factories that need stable, high-yield output of hot melt glue. An EVA hot melt glue production line turns solid EVA resin, tackifying resin, wax, antioxidant and filler into a uniform melt, and then extrudes, cools, cuts and packs it into finished hot melt glue products — in one continuous, fully automated flow, from powder feeding and reactor melting to extrusion, cooling, cutting and packaging.

EVA Hot Melt Glue Production Process

What Is EVA Hot Melt Glue?

EVA hot melt glue is a solvent-free, water-free, 100% solid fusible polymer. It is solid at room temperature and becomes a flowable liquid adhesive with a certain viscosity when heated and melted to a certain degree. After melting, it is light brown, translucent, or native white. Because no solvent or water is involved, an EVA hot melt glue production line is a cleaner and more energy-efficient route than solvent-based adhesive manufacturing.

11. Chiller system
12. Packaging system
13.  

Reactor: The Core of the EVA Hot Melt Glue Production Line

The reactor is the melting and mixing vessel at the heart of the EVA hot melt glue production line. EVA resin, tackifying resin, wax, antioxidant and filler are fed into the reactor, heated and mixed into a uniform, bubble-free melt, and then transferred to the screw extruder for extrusion and shaping. Because the reactor controls melting temperature, mixing uniformity and melt viscosity, it directly determines the consistency of the finished glue and how stable the downstream extrusion, cooling and cutting process will be.

EVA Hot Melt Glue Formula

The reactor and the downstream units of the EVA hot melt glue production line are configured around this formula, so the same line can run different recipes without changing the overall process flow.

How the EVA Hot Melt Glue Production Process Works

1. Feeding and storage — EVA resin, tackifying resin, wax, antioxidant and filler are fed and stored through the powder feeding, air storage, material storage and dust filtration systems.
2. Melting and mixing — the raw materials are heated and homogenised inside the reactor into a uniform melt.
3. Transfer and filtration — the melt moves through the mixture transfer tank to the screw extruder.
4. Extrusion and shaping — the screw extruder and die head form the melt into the required profile.
5. Cooling — the extruded material is cooled in the conveying water sink and chiller system.
6. Cutting and packaging — the cooled material is cut and packed into finished hot melt glue products.

2. Anti-sticking and dust removal design
   1. Nano Teflon coating on the inner wall of the die head reduces the adhesion of the molten glue and allows continuous operation for 24 hours without material accumulation.
   2. An electrostatic dust removal device is integrated in the cooling section to prevent impurities from being adsorbed on the surface of the glue stick.
       

FAQ: EVA Hot Melt Glue Production Line and Reactor

Q: What is an EVA hot melt glue production line?

A: It is a continuous production system that melts, mixes, extrudes, cools, cuts and packs EVA-based hot melt glue. It usually includes feeding and storage systems, a reactor, a screw extruder, a cooling system, a cutting unit and a packaging system.

Q: What is the role of the reactor in an EVA hot melt glue production line?

A: The reactor is where EVA resin, tackifying resin, wax, antioxidant and filler are melted and mixed into a uniform melt. It controls melting temperature, mixing uniformity and melt viscosity, and therefore has a direct impact on the quality of the finished hot melt glue.

Q: Can one EVA hot melt glue production line run different glue formulas?

A: Yes. The reactor and the downstream extrusion, cooling and cutting units can be adjusted for different recipes, so the same production line can produce different EVA hot melt glue products.

Q: Why do some hot melt glue production lines produce glue sticks with tails?

A: Tails (a non-smooth granule shape with drawing or tailing) usually come from unstable cutting temperature and inaccurate temperature or viscosity control. JCT's high-precision cutting technology, accurate temperature control and rapid water/air cooling keep the particle shape consistent and eliminate wire-drawing tails.
