The High Viscosity EVA Granular Hot Melt Adhesive Production Line is engineered to transform raw polymers and resins into perfectly formed, industrial-grade adhesive granules. Designed for large-scale manufacturing operations, this heavy-duty system integrates advanced rheology control, precise thermal management, and automated extrusion to deliver consistent batch output. Whether formulating for intricate woodworking, high-speed bookbinding, or demanding packaging applications, this complete equipment configuration provides the reliability and flexible production capacity required to scale your manufacturing footprint.
The heart of the line features a heavy-duty SS304 stainless steel reactor. The smooth, polished interior surfaces resist chemical corrosion and prevent material buildup, ensuring rapid cleaning between batch changes. Advanced thermal sensors provide granular control over heating and cooling cycles, allowing operators to precisely manage the rheology and viscosity of complex formulations—including EVA resins, tackifiers, waxes, and antioxidants. This meticulous temperature regulation ensures uniform homogenization, preventing localized overheating and thermal degradation.
FLEX Machinery Co., Ltd. delivers a complete turnkey engineering solution, guiding you from initial facility layout planning to final equipment commissioning. Beyond supplying the physical machinery, our technical experts provide comprehensive formula technology support. We assist in fine-tuning custom formulations for specific applications, such as heavy-duty edge banding or rapid-set packaging adhesives. Our hands-on operator training ensures your team can confidently manage the entire production cycle from day one, maximizing your market competitiveness.
Engineered to maximize operational efficiency, the intelligent PLC control system automates the entire sequence—from raw material feeding and reaction to extrusion and pelletizing. This drastically reduces the need for manual intervention, mitigating human error. Furthermore, the system incorporates energy-optimized heating loops and high-efficiency drive motors. This strategic energy management lowers daily utility consumption and accelerates your overall return on investment.
One of the most persistent challenges in adhesive manufacturing is the "drawing" or "tailing" of granules. Our production line resolves this through a specialized underwater or air-cooling pelletizing mechanism combined with a precision rotary cutting head. This ensures every granule is perfectly spherical and uniform in size, free from irregular shapes or strings. Every unit undergoes strict factory quality inspections and complies with international ISO quality management standards, guaranteeing safe and reliable long-term operation.
Recognizing that operational scales vary, this production line supports extensive non-standard customization. Whether you require a compact 2000L setup or a massive 6000L high-capacity system, we tailor the reactor volume, extrusion speed, and packaging integration to match your facility's footprint. The system easily adapts to diverse raw materials, efficiently switching between EVA, polyamide, and polyester-based adhesive runs to meet changing market demands.

Operation Guide for Flex's Granular Hot Melt Adhesive Production Line
This concise guide helps operators quickly master the core operation process, detailing the complete equipment configuration from the reactor and filtration system to the extruder and packaging unit, ensuring safe and efficient production.
Complete safety checks: Confirm emergency stops, safety guards, and ventilation systems are in optimal working condition.
Inspect equipment: Visually check the stainless steel reactor, multi-stage filtration system, feeding system, high-torque extruder, and granulator for any abnormalities.
Prepare materials: Sort raw materials (EVA, wax, tackifiers) per the optimized formula, and input specific thermal production parameters into the PLC control system interface.
Start the energy-efficient reactor preheating cycle, then run automatic feeding and the quiet, heavy-duty stirring motor for raw material reaction.
After the reaction and homogenization are completed, transfer the viscous adhesive through the filtration unit to the extruder for plasticizing and strip extrusion.
The precision granulator cuts the extruded strips into uniform, string-free granules, which are then rapidly cooled, screened, and collected by the automated packaging machine.
Shut down the system in a strict sequence: feeding → stirring → heating → extrusion → main power supply.
Clean residual adhesive in the reactor walls, transfer pipelines, and granulator cutting head while warm to avoid permanent solidification.
Perform daily maintenance: Check wearing parts, add lubricant to drive motors, and record daily production data for yield tracking.
For common issues like uneven granules or abnormal motor noise, refer to the comprehensive manual for rapid diagnostic fixes.
