Can handmade spine hot melt adhesive granules and machine adhesive granules be used interchangeably? Compare before making a decision

Direct answer: It can be used, but it is not recommended to exchange it for a long time

Manual work (glue pot, hand-held glue gun repairing spine) and machine glue assembly line, forHot melt adhesive granulesThe requirements are in the opposite direction: manual work requires long open time and easy operation, while machine use requires fast initial adhesion and the ability to keep up with online speed. There is not a big problem with short-term emergency mutual use, but long-term mixed use will compromise both yield and efficiency.

Key Differences Comparison

What will happen if there is an exchange

• Machine glue for manual use: curing too quickly, shaping before alignment, crooked spine, and excessive rework;
• Handcrafted glue is taken to the machine: the opening time is too long, and after pressing, it enters the next workstation without shaping, resulting in displacement and virtual adhesion;
• Handmade glue pot long-term insulation machine materials: repeated heating is prone to carbonization, producing black slag and burnt smell.

How to configure more reasonably

It is recommended to prepare materials separately by workstation: the machine should be of the quick fix type, while the repair and sample book tables should be of the long open time type. Both should be labeled and stored separately to avoid mixing. Stores with small usage can only prepare one universal type, but they need to accept a compromise of compromise. Sunlife’s hot melt adhesive book series is available in both organic fast curing and manual long opening directions. Guangzhou Sunlife Trading can provide small batch combination supply solutions according to your workstation configuration.

Remedial measures during emergency exchange

If there is indeed a temporary shortage of materials that must be exchanged, the impact can be minimized by adjusting parameters: when using machine made quick fix materials for manual use, the glue temperature should be appropriately reduced by 5-10 ℃ and the amount of glue taken at a time should be reduced to save some operating time; If the manual long open material is temporarily placed on the machine, the pressing pressure should be increased, the holding time should be extended, and the line speed should be reduced. These are all emergency measures, and the corresponding brand should still be replaced after the order is fulfilled.

Frequently Asked Questions

Q1: The graphic and text store only wants to prepare one type, which one should I choose?
If the machine is the main one, choose the machine with fast curing type. When repairing manually, reduce the glue temperature appropriately to extend the operable time.

Q2: Can two types of glue be mixed in the same glue pot?
Not recommended, compatibility and curing speed are inconsistent, which can easily cause delamination and affect strength.
