During the production of hot melt glue granules (such as EVA, PA, PES and PO), many manufacturers frequently encounter a range of challenges: high material viscosity leading to uneven mixingl fruquent blade sticking and die clogging during pelletizing; granule agglomeration or clumping after packaging; and even significant production losses caused by frequent downtime for cleaning.
As a professional manufacturer of hot melt glue pelletizing production lines, JCT fully understand the challenges posed to actual production by the material characteristics of hot melt glue —specifically their strong tack, high heat sensitivity, and slow coolin rates. We believe that "understanding the pain points is key to building superior equipment". By implementing targeted design upgrades across core systems—including reaction, extrusion, pelletizing, and cooling—we deliver production line solutions that offer high automation, continuous stability, and exceptional output capacity.
Ⅰ. Pain Points in Compounding and Reaction: High Viscosity, Susceptibility to Degradation and Uneven Dispersion
Customer Pain Points: There are significant disparities in melting points and viscosities among the tackifying resin, base resin and wax; traditional equipment is prone to creating "dead zones" during compounding. Furthermore, prolonged high-temperature shearing can cause material discoloration, yellowing, or even carbonization.
Our Equipment Optimization Solution:
• High-shear Screw Reactor Blade Design:Utilizes an optimized screw configuration and multi-zone independent temperature control to precisely balance high-viscosity materials while preventing localized overheating.
• High-efficiency Vacuum Degadding System:A high-vacuum degassing unit is integrated into the mixing section to rapidly remove trace moisture and volatiles, effectively eliminating internal bubbles and enhancing the transparency and density of the finished product.
Ⅱ. Pain Points in Pelletizing and Die-head: Knife Adhesion, Die Clogging and Irregular Pellet Shape
Customer Pain Points:During underwater or water-ring pelletizing, even slight deviations in discharge temperature can lead to issues—such as knife adhesion and shaft wrapping (due to high temperatures) or die clogging (due to low temperatures)—forcing frequent shutdowns for cleaning.
Our Equipment Optimization Solutions:
• Intelligent Precision Die Head with Constant Temperature Control:Features a flow-channel design optimized via flow-field simulation and a zoned heating/cooling temperature control system. This ensures highly consistent pressure and temperature across all die outlets, effectively eliminating uneven output and "freeze-off" (die face solidification) issues.
• Non-stick Coated Cutter Head and Adaptive Blade-feed System:The cutter head surface features a wear-resistant, non-stick coating. Paired with a pneumatic or hydraulic adaptive feed mechanism, it maintains a precise, micro-gap contact between the blades and the die face, ensuring clean, crisp pellerizing while preventing agglomeration and blade adhesion.
Ⅲ. Pain Points in Cooling and Packaging: Hard Exterior/Soft Interior and Re-agglomeration After Packaging
Customer Pain Point:Although the pellet surfaces appear set after cooling, residual internal heat remains; under the pressure of stacking after packaging, the pellets fuse back together into clumps (bridging/agglomeration), leading to customer returns.
Our Equipment Optimization Solution:
• Multi-stage Deep-cooling Fluidized Bed System:Following underwater pelletizing, a high-frequency centrifugal dewatering unit and a multi-stage pneumatic fluidized bed are employed to extend the cooling path, achieving thorough cooling from te outside in.
