There are some requirements, but they are not restrictive.
Different shapes primarily depend on the compatibility of the hot melt glue's fluidity (viscosity), cooling method, and molding equipment.
| Hot melt glue has high viscosity | Hot melt glue has low viscosity |
| It has poor fluidity and does not easily fill the mold cavity | It has good fluidity and is easier to mold |
| Molding speed is slow | Fast molding efficiency |
| Suitable for making blocky, large, and pillow-shaped or other thicker shapes | Suitable for thin/small shapes such as granules, stripes and sheets |
| Requires higher extrusion pressure or higher heating temperature | Requires less demanding equipment |
| Hot melt glue shape | Viscosity requirement | Reason |
| Block | Wide tolerance, both high and low viscosity are acceptable | Primarily relies on filling and molding, does not require high fluidity |
| Pillow | Medium viscosity is preferred | Requires extrusion and slicing; high viscosity makes extrusion difficult |
| Strip (stick) | Medium fluidity | Requires uniform extrusion of strands; high viscosity affects shape stability |
| Granule | Slightly low viscosity | Droplet speed is affected by viscosity; high viscosity easily causes stringing |
| Sheet | Medium to low viscosity | Requires uniform leveling; high viscosity prevents even spreading |
The viscosity of hot melt glue does affect different shapes, but it does not limit production.
JCT can design a suitable extrusion, cooling, granulation, or molding system for oure customers based on the actual viscosity of their hot melt glue, enabling stable production of any shape, including blocks, strips, pillows, sheets and granules.
