Many book and magazine factories purchase hot melt adhesive granules based on “feeling”, resulting in either material shortage, production stoppage, or stockpiling and occupying warehouses. In fact, the dosage can be calculated very accurately: the glue consumption per book ≈ the spine coating area x the glue layer thickness x the glue density. Taking an A5 book with a spine width of 2cm, a coating height of 2cm, and a glue thickness of 0.3mm as an example, a single book weighs about 0.12 grams, and 10000 books weigh 1.2 kilograms.
| Steps | method |
|---|---|
| 1. Test single book | The difference in weight between the empty spine of the book and the adhesive coating results in adhesive consumption per book |
| 2. Categorize by category | Record separately by paper type and thickness, and establish a glue consumption ledger |
| 3. Batch production | Single book glue consumption x planned number of volumes x 1.05 loss coefficient |
| 4. Customized procurement | Based on inventory and delivery time, determine the quantity for each purchase |

Question: Does overflow glue count as loss?
Answer: Calculate. Excessive glue overflow indicates incorrect coating parameters or glue type, and adjusting the machine is more cost-effective than buying more glue.
Q: How to estimate small batch trial orders?
Answer: First, use the machine scale difference method to measure dozens of books and take the average, then enlarge it, and the error is very small.
