Product Description

The high-viscous hot melt glue sticks Specially customized for complex materials

Engineered for demanding industrial applications, our high-viscosity hot melt glue sticks deliver superior bonding strength on challenging substrates like fabrics, leathers, shoes, and delicate electronic components. Specially formulated to handle intricate assemblies, they ensure a durable, flexible, and precision-driven bondeven in high-speed production environments.
Key Technical Advantages
PerformanceGood liquidity provides exceptional gap-filling capability for uneven or porous surfaces (e.g., textiles, leather stitching).
Superior heat resistance maintains bond integrity under mechanical stress and temperature fluctuations.
Material Mastery:
Engineered for complex substrates: Strong adhesion on synthetic fabrics, PU leather, rubber soles, and coated electronic parts.
Flexible yet tough formula prevents cracking or brittleness in dynamic applications (e.g., footwear flex zones).
Operational Efficiency:
Optimized melt flow reduces stringing and dripping, minimizing waste and cleanup downtime.
Extended open time allows precise positioning in manual or automated assembly processes.
Ideal for:
Footwear Manufacturing Securely bonds soles, insoles, and decorative elements without delamination.
Textile & Leather Goods Reinforces seams, hems, and embellishments on bags, apparel, and upholstery.
Electronics Assembly Encapsulates wires and components with low-electrical-conductivity formulations.
Built for reliability in high-precision bonding, these glue sticks ensure zero compromises on strength or speedwhere complex materials meet industrial demands.

FAQ

1. The Nozzle Or Hose Is Clogged?
Solution:
Increase temperature or switch to low-viscosity glue
→ Raise glue tank temperature by 5~10°C or use a lower viscosity adhesive for smoother flow.
Clean the glue path system
→ Turn off heating, disassemble nozzle/hose, and thoroughly purge with a dedicated cleaning solvent for optimal performance.
Prevent recurrence
→ Empty glue system if idle for more than 30 minutes; ensure daily cleaning of the spray head after operation.

2. Hot Melt Adhesive Is Carbonized?
Solution:
Reduce temperature immediately
→ Lower glue tank temperature by 10~15°C, ensuring it stays within the safe range specified in the technical manual.
Remove carbonized residue
→ Begin by draining the old glue and meticulously scrubbing the tank using a brass brush. This crucial step helps in eliminating any carbon deposits that may have formed.
Ensure glue refill is conducted with precision and care.
→ Maintain a glue level that is greater than 50% during operation. This is essential to prevent any risk of overheating.

3. Is Your Hot Melt Adhesive Gelled?
Solution:
Immediately cease use and proceed to clean the entire system thoroughly.
→ Carefully drain the gelled glue and flush both the tank and pipes using hot oil, ensuring the temperature does not exceed 120°C.
Consider switching to a different adhesive type.
→ Replace the current batch with a new one and consult your supplier for an anti-gelling formula to prevent future occurrences.

4. Are You Experiencing Bubbling in Your Hot Melt Adhesive?
Solution:
Lower the temperature and allow the glue to settle.
→ Set the temperature to the minimum recommended range and let the glue settle for a minimum of 30 minutes before using it.
Opt for a low-moisture adhesive.
→ Select vacuum-sealed glue or request a dry formula from your supplier to ensure optimal results.

5. Is There Smoke Emitting From Your Hot Melt Adhesive?
Emergency Response:
IMMEDIATE SHUT DOWN REQUIRED
→ Instantly cut power to all heaters and activate your ventilation systems.
Inspect the temperature controls thoroughly.
→ Conduct tests or replace any faulty sensors and controllers to ensure proper functionality.
Switch to an adhesive that can withstand higher temperatures.
→ Utilize a higher flash-point glue if smoke continues to persist at normal operating temperatures.
