How to choose fast curing hot melt adhesive particles for urgent orders that require pick-up on the same day of graphic and text printing? Operation Guide

Direct answer: Choose a fast curing grade with short opening time and high initial adhesion

The biggest fear for graphic and text fast printing shops is that customers will say ‘get it in an hour’. To ensure that the bidding documents and sample books can be cut and bagged after being glued, it is necessary to choose a fast curing type with a short opening time (about 3-8 seconds) and high initial adhesionHot melt adhesive granulesIn this way, it takes only a few seconds to set after gluing and a few minutes to enter the cutting process, without having to wait for more than half an hour.

Four step operation

• The first step in material selection is to clarify the purpose of “urgent orders and quick solidification” with the supplier, request the opening time and initial adhesion data, and avoid using generic hard paste;
• Step 2 Preheating: Raise the glue cylinder to the recommended temperature 15-20 minutes before starting up, and the temperature should not cause false sticking;
• Step 3: Test the first book: Before making the formal order, first glue a sample of the same paper and thickness, flip and pull it to be qualified, and then batch it;
• Step 4: Cooling and shaping: After gluing, let it cool naturally for 3-5 minutes before cutting, do not immediately put it on the paper cutting machine.

Common Paper Corresponding Strategies for Urgent Orders

Solidify parameters into job cards

Urgent orders are most afraid of last-minute trial and error. Suggest writing down the glue temperature, glue amount, and pressing time of commonly used paper into a “Urgent Glue Assembly Operation Card” and sticking it on the edge of the machine. Novices can follow it. Sunlife hot melt adhesive is available in quick fix small packaging pellets for graphic and text printing. It is packaged in 25kg bags and suitable for store turnover. Guangzhou Sunlife Trading supports small batch trials and free trial of commonly used paper patterns.

Quick Tips for Scheduling Urgent Orders

Upon receiving the pick-up task on the same day, prioritize the order of “thick materials first”: the cooling and shaping of thick materials is slow, so let them cool naturally first. During this time, make thin materials, and finally cut and bag them uniformly, which can significantly shorten the overall delivery time. In addition, do not frequently turn on and off the melt glue pot in the store to save electricity. Keeping it at a constant temperature for multiple orders a day is actually more convenient and avoids the first piece being unstable every time it is reheated.

Frequently Asked Questions

Q1: Is fast curing adhesive not as effective as slow curing?
No, the fastness depends on the resin and penetration, not the curing speed; But the short opening time requires a continuous gluing and pressing action.

Q2: How long can it be cut?
Cool at room temperature for 3-5 minutes for basic shaping, and it is recommended to cool for 10 minutes for thick samples.

Q3: Can we use quick fix adhesive for all tasks?
For flat brochures that require flexibility, it is still recommended to use high elongation grades.
