● High-precision Closed-loop Circulating Water Cooling System
With an intelligent closed-loop circulating water system, the equipment achieves ±0.5℃ temperature control accuracy for uniform HMPSA product cooling. It cuts water consumption by 60% versus open systems, slashing operational costs. The design avoids product hardness inconsistency and deformation caused by temperature fluctuations, stabilizing adhesive physical and chemical properties.
● Provide Formula Technology Support
FLEX Machinery Co., Ltd. supplies customers with high-quality, cost-effective HMPSA packaging machine lines, and also offers professional formula technical support. The support covers diverse adhesive types including hygiene adhesive, elastic adhesive, high viscosity structural adhesive, hydrogenated petroleum hydrocarbon resins based low temperature structural adhesive, complex film adhesive and positioning adhesive.
● 304 Stainless Steel Structure for Long Service Life
The tank and internal parts adopt 304 stainless steel for superior corrosion and high-temperature resistance. It supports 24-hour continuous operation in harsh environments, with an 8+ year service life—30% longer than ordinary carbon steel equipment. Its smooth inner wall is easy to clean and maintain, meeting industry safety standards and reducing maintenance frequency.
● Customizable Speed Matching for Versatile Production
Stepless speed regulation fits 5–20m/min production lines, adapting to pillow-shaped HMPSA products of different specs. The modular connection design enables quick docking with existing lines without workshop reconstruction, shortening installation and commissioning to 3 working days. It helps enterprises expand product categories and boost line utilization.
● Efficient Shaping to Reduce Product Defect Rate
Equipped with a multi-stage gradient cooling zone, it cools products gradually from 120℃ to room temperature, avoiding thermal shock damage. Optimized water flow ensures synchronous cooling of all product parts, cutting defect rate to below 0.3%. The stable shaping effect enhances adhesive bonding strength and tensile performance, boosting market competitiveness.
● Energy-saving & Environmentally Friendly Operation Design
The intelligent energy-saving control system adjusts pump power and cooling capacity based on production load, saving 25% energy versus traditional equipment. It has zero wastewater discharge, complying with national environmental standards. With noise ≤ 60dB, it improves workshop environment and reduces operators’ occupational health risks.

PSA Pillow-shaped Hot Melt Adhesive Cooling Water Tank Operation Guide:
1. Pre-Startup Inspection
Check if the closed-loop water system is full and leak-free, ensure 304 stainless steel tank is clean. Confirm power supply and wiring are normal, and the intelligent control panel displays no faults before starting.
2. Startup Operation
Set the target temperature (25-120℃) on the control panel, start the circulating water pump. Wait for the system to reach stable temperature (±0.5℃) before connecting to the HMPSA production line.
3. Operation Monitoring
During operation, monitor temperature, water flow and noise (≤60dB). If deviations occur, adjust via the intelligent panel. Observe adhesive granule shaping, and adapt to line speed (5-20m/min) timely.
4. Shutdown Process
Stop feeding first, keep the water system running until temperature drops to room temperature. Turn off the pump and power, clean the tank inner wall to extend service life.
1. Q: Why is the temperature control accuracy unstable?
A: Check if the closed-loop water flow is smooth and the temperature sensor is clean. Blockage or contamination may cause deviations. Adjust pump power via the panel and ensure no water leakage.
2. Q: How often should the equipment be maintained?
A: Clean the 304 stainless steel tank weekly. Replace circulating water monthly and inspect seals quarterly. Regular maintenance extends service life and ensures stable operation.
3. Q: Can it adapt to different production line speeds?
A: Yes. It supports stepless speed regulation for 5-20m/min lines. Adjust cooling capacity via the intelligent panel to match speed changes and maintain shaping effect.
4. Q: What to do if the operation noise exceeds 60dB?
A: Abnormal noise is usually from pump wear or pipe vibration. Stop the machine to check pump parts and fasten pipelines. Replace worn parts promptly to avoid further damage.
