4 management of droplet forming

4.1 Human factors in droplet forming

The five elements of droplet forming determine the ideal material shape.
And these five elements depend on the operator to grasp.
Therefore, under the guidance of noble professional ethics, operators should treat every small link in the operation seriously with a warm and responsible attitude.

4.2 Develop good habits of observation and judgment

4.2.1 the ideal dripping material is the first key link in the forming process of row and column bottles.
Operators must attach great importance to it and take it seriously.
After adjusting the relevant process parameters to reach the ideal state, the first requirement is its stability.
On the other hand, the influence of the fluctuation of feed temperature on the shape of the material is often fatal.
Therefore, operators must form the habit of paying great attention to observing the shape of material droplets.
And make an accurate judgment through delicate observation.
This kind of homework is easy to say, but it is difficult to really do it and do it in place.
The habit of observation is formed by the accumulative process of the operator.
What`s more, it is a summary that the operator speculates carefully and even understands it.
Careful observation is necessary.
4.2.2 observation and judgment.
Observe the intuitive key points of droplet forming:
The main results are as follows: 1) the instantaneous shape of the droplet in the flowing bowl is consistent with the surface temperature.
Is there a difference between yin and yang in each drop?
2) the instantaneous shape of the droplet when it comes out of the bowl, the consistency between the two droplets.
There is often a more obvious dark band between the two.
3) the instantaneous shape of the droplet when it comes out of the bowl is the same length of the two droplets?
The length of material shape change will be different.
4) the shape of the droplet at the moment when it flows out of the bowl. Is there any bending in the shape of the droplet?
This may be caused by factors such as temperature.
5) is the shape of the material droplet sloshing at the moment after shearing?

4.3 Thinking, analysis and accurate judgment

Through the delicate observation of many of the above items, the operators calmly think about the causes of the analysis.
Then make an accurate judgment and then adjust it.
From the point of view of systematic thinking, for double-drop or three-drop material, the height difference of two drops before leaving the steering groove and falling into the primary mold funnel can be regarded as the most intuitive criterion to judge the state of the flow system.
It is also related to the operation related to droplet forming and the action of the shearing system.
