What problems should be paid attention to when choosing glue filling machine?

The choice of glue filling machine depends on practical application and comprehensive consideration. For example, two-component glue filling machine can be divided into dynamic mixing and static mixing. In view of the disparity in proportion, the weight mixing ratio is more than 65,438+000: 7, and there are less fillers in the glue, and the curing time of the glue after mixing is longer, so the dynamic mixing glue filling head can be selected. If the mixing ratio of glue is less than 65,438+000: 7, it means that there are more fillers in the glue. Then dynamic mixing is not suitable, because the filler in the glue will wear the stirring head in the dynamic mixing head, and dynamic mixing needs constant cleaning to ensure that the glue injection head is relatively clean and not blocked, so the curing time is prone to gambling. Here you can choose static mixing, measuring with cylinder liner and mixing with mixing tube.

In addition, if there are requirements for the curing effect of glue, such as no bubbles, then you should choose a vacuum glue filling machine. The glue filling environment is all in a vacuum environment, and the glue can be fully pressed into every gap in the product by vacuumizing, which will make the glue filling effect very dense and play a multiplier role.

In addition, the two-component glue needs pretreatment, and most of the glue needs vacuum defoaming, stirring and recycling, so as to completely eliminate bubbles in the glue and minimize the possibility of bubbles in the glue filling process. Some glues have fillers, so they need to be stirred and recycled to maintain the uniform composition characteristics of the glue.

In addition, it depends on the accuracy of glue filling, including proportional accuracy and glue discharging accuracy. Precision control is actually a big problem. Different glue filling machines are very different, and the maintenance cost should also be considered.
