The capacity of the glue pot on the market varies from 1.5L to 8L, with 2L and 5L being the most common in graphic stores. Choosing a larger capacity wastes space and heating energy, while choosing a smaller capacity can affect efficiency due to frequent glue addition. The following is a comparison of actual measurements of two mainstream capacities.

| indicator | 2L glue pot | 5L glue pot |
|---|---|---|
| Glue loading amount (approximately) | 1.8kg | 4.5kg |
| Heat up to working temperature | 15 minutes | 30 minutes |
| Aging rate of adhesive solution | Fast (less quantity, frequent cycles) | Slow (large volume, good thermal stability) |
| Suitable for daily production | <100本 | 100-500 books |
| Glue frequency | Every 2-3 hours | Every half day |
| Floor area | compact | larger |
Small graphic and text store (daily average)<50本装订)→ 2L够用,升温快、占地小。中型图文/快印店(日均100-300本)→ 5L更合适,减少加胶频次、胶液热稳定性更好。森莱热熔胶粒适配所有主流胶装机,选胶不受锅容限制。
Q: Is it easier for the glue to age if the small pot changes glue more frequently?
A: Yes, it is. The small pot has a low amount of glue, a high mixing ratio of new and old glue, and a longer overall heat history. Suggest cleaning the 2L pot once a week and replacing it with new glue.
Q: What should I do if the glue pot is too big and heats up slowly?
A: You can start preheating 30 minutes in advance, or choose a glue machine with fast heating function.
Direct answer: For paper bag rope adhesion, hot melt adhesive particles with high initial adhesion, good flexibility, and a softening point of 75-85 ℃ should be used. The diameter of the adhesive point should be 8-12mm, with one point at each rope hole. Press and hold for 3-5 seconds.The key is not in the amount […]
The automatic sealing machine uses hot melt adhesive particles to seal the box, and the process can be summarized as six steps: cleaning and inspection → preheating with adhesive → setting temperature → adjusting the amount of adhesive sprayed → adjusting the sealing test → mass production. Novices can follow the instructions and get started […]
Direct answer: Glue overflow dirtying the book pages is essentially due to at least one of the four variables, “glue amount, temperature, pressure, and rhythm,” exceeding the appropriate range. The three most common reasons are excessive glue application, high glue temperature leading to low viscosity, and excessive clamping pressure squeezing glue from the spine to […]
Direct answer: There are three main methods for testing the binding strength of books and periodicals – spine tension (page tension) test, repeated folding test, and drop and stacking test. If only one type is selected, publications should be given priority for page pull-out force testing; To cover real usage scenarios, the combination of tension […]
