Glue making machinery

 In Blog

The manufacturing of glue involves several steps and requires specialized machinery to ensure efficient production, consistency, and quality. Depending on the type of glue being produced—such as water-based, solvent-based, hot melt, or epoxy—different machines and equipment are necessary. Below is an overview of the key machinery used in the glue-making process:

  1. Mixing Tanks
  • Purpose: To blend raw materials and polymers thoroughly.
  • Features: These tanks are typically made of stainless steel to prevent corrosion and contamination. They are equipped with agitators     high-shear mixers that ensure all components, including resins, solvents, and additives, are evenly mixed.
  1. Dissolvers
  • Purpose: To dissolve solid materials into liquids, particularly useful in the initial stages of water-based or solvent-based adhesive formulations.
  • Features: High-speed dissolvers that create a vortex to draw solids into the liquid, ensuring quick and efficient dissolution.
  1. Reactors
  • Purpose: For chemical synthesis where precise conditions of temperature and pressure need to be maintained to facilitate chemical reactions, especially in making epoxies or polyurethanes.
  • Features: Equipped with temperature control systems, pressure monitors, and powerful agitators. They are often jacketed for heating or cooling.
  1. Extruders (for hot melt adhesives)
  • Purpose: To melt and mix thermoplastic polymers and additives, commonly used in the production of hot melt adhesives.
  • Features: These machines apply heat and pressure through a screw system to melt the components, which are then extruded in a continuous process.
  1. Homogenizers
  • Purpose: To further refine the mixture and ensure uniformity in particle size, especially critical in high-performance adhesives where consistency is key.
  • Features: These machines reduce particle sizes by forcing the adhesive mixture through a narrow space under high pressure.
