How to use edge banding hot melt adhesive

1. You need to communicate your needs with your glue supplier (bonded boards, edge banding materials, machine edge banding speed, glue melting temperature and final strength, etc.), and provide reasonable edge banding hot melt glue for use.
2. Put the glue into the glue pot and melt it to the specified temperature. After the edge banding machine temperature panel shows that the temperature has been reached, the glue will flow to the glue roller that has been adjusted to the optimal glue coating amount (the board can just pass through the glue coating shaft).
3. The surface of the board will be coated with glue, the edge banding material will also pass through at the same time, and the pressure roller will make the board, glue and edge banding material closely contact each other, and then trim and polish them.
4. The glue will gradually cool down, the board and the material will be bonded together, and the edge banding process is completed.

Materials suitable for edge banding

(PVC、ABS、Acrylic、Kraft paper、Non woven wood veneer、Solid wood veneer、Wood chips etc.)

Application notes

1.  The moisture content of wood should be controlled at 8-12%, and the surface of the base material should be flat, smooth and not warped.
2.  Keep the glue tank clean. During normal use, if the amount of glue is less than half, you need to add glue particles in time.
3. When the colloid melts to the point where there are no particles, the equipment can be adjusted; after the glue temperature is stable, the temperature measurement equipment can be used to check the temperature and make adjustments based on the actual temperature. Check the temperature of the glue coating wheel and adjust it to ensure normal glue flow.
4. When the actual temperature of the colloid drops by more than 5°C during use, the corresponding temperature of the equipment needs to be increased; when the amount of glue used is large and the melting speed is insufficient, the equipment temperature can be appropriately increased to supplement it, but intermittent production is required.
5. Feeding speed: 15-30 meters/minute
6. After the pressure is relieved, it should be aged for a period of time (more than 24 hours in winter and more than 18 hours in summer) before entering the next processing step.
7.  When testing is required, please test at least 7 days later to ensure accurate test results.
8. The humidity of the substrate is controlled within the range of 8-12%. When the temperature drops to 10-15°C, the equipment temperature needs to be increased by 10-15°C and the equipment operation speed should be accelerated appropriately.

EVA Edge banding Hot Melt Adhesive FAQs

Q1.What is the difference between EVA edge banding hot melt adhesive and PUR edge banding hot melt adhesive?

A1. EVA hot melt adhesive is a hot melt adhesive formed by copolymerization of ethylene and vinyl acetate under high pressure. Its characteristics are simple operation, manual operation, high cost-effectiveness, and certain tensile strength. PUR hot melt adhesive is a reactive polyurethane hot melt adhesive, characterized by high production process requirements, small adhesive lines, good moisture resistance, and higher tensile strength than EVA hot melt adhesive.

Q2.Why does the edge banding strip immediately fall off after the edge banding is completed?

A2.a. The operating environment temperature is too high or too low. b. The amount of glue applied is too low. c. The moisture content of the board is too high. d. The board or edge bangding material contains grease, which prevents the glue from penetrating.

Q3.Why does the glue shaft produce “glue threads”?

A3.a. The temperature setting of the edge banding machine is too low. b. The amount of glue applied is too large. c. There is direct air blowing directly towards the glue coating shaft. d. The selected adhesive has too high viscosity.

Q4. Why is there adhesive attached to the surface of the board after edge bangding?

A4. a. The amount of glue applied is too large. b. The cleaning module of the edge banding machine is damaged. c. The sol temperature of the edge banding machine is set too high.

Q5.Why does the color of hot melt adhesive deepen in the melting pot?

A5.a. The heating time of hot melt adhesive in the glue pot is too long. b. The thermal sensing device of the edge banding machine is damaged, resulting in consistently high temperatures and carbonization of the adhesive. c. Hot melt adhesive is stored for too long, and the adhesive undergoes oxidation reaction.

Q6.Why does the edge banding immediately detach during the trimming process?

A6. a. Insufficient glue application. b. The temperature of the board or edge banding is too low. c. The conveyor belt speed of the edge banding machine is set too low. d. The pressure of the edge banding machine is too low.

Q7. Why is the initial bonding of the edge banding board not good?

A7. a. The roller pressure of the edge banding machine is too low. b. The edge banding board is too long and the front end is subjected to uneven force. c. The initial adhesive strength of the selected hot melt adhesive is too low.

Q8. Why is there a concave convex phenomenon on the edge banding of the finished product?

A8.a. The glue is contaminated with dust at the hot melt glue pot. b. There is rubber on the surface of the coated shaft. c. The processing accuracy of the board is insufficient.
