Viscosity and fluidity requirements of silicone for trademark dispensing machine
Viscosity requirements:
The viscosity needs to be moderate, neither too high nor too low. If the viscosity is too high, the silicone will have difficulty flowing during the dispensing process and it will be difficult to evenly flow out through the dispensing needle, which may cause uneven dispensing of the trademark, with too much glue in some areas and insufficient glue in some areas, affecting the integrity and aesthetics of the trademark.
On the contrary, if the viscosity is too low, the fluidity of the silicone is too strong, and the size and shape of the glue dots may not be accurately controlled, and it is easy to flow and diffuse, which is also not conducive to accurate dispensing of the trademark and presenting a good appearance effect.
Fluidity requirements:
Good fluidity is the key to ensuring smooth dispensing of the trademark. The silicone should be able to flow smoothly through the dispensing needle under appropriate dispensing pressure and accurately flow to the position where the trademark needs to be dispensed according to the predetermined dispensing path. This requires that the silicone has stable flow characteristics under the dispensing speed, pressure and other parameters set by the dispensing machine, so that the trademark dispensing operation can be completed efficiently and accurately.
