In recent years, the rapid development of industrial automation, many enterprises are using glue pouring machine instead of manual, the use of glue pouring machine can not only save labor but also improve production efficiency! But in the process of using glue pouring machine, we will inevitably encounter such problems, if we do not carry out professional treatment, it will affect our glue filling efficiency, the following jingrenda precision technical personnel will come For you to explain the filling machine after curing the cause of bubbles!


Factor 1: during the filling process of the glue filling machine, the air enters into the glue mixing process. During the injection of the product and the whole curing process, the air is not completely evacuated, and a lot of air enters!


Phenomenon: small bubbles are produced after curing


After mixing the main agent and curing agent together, we can extract the air from the glue through the double liquid glue pouring machine, and then turn on the heating system of the glue pouring machine to preheat the products to be potted, and then we can choose to carry out the pouring and curing work in a humid environment, which can effectively guarantee the production of bubbles after the pouring and curing of the glue pouring machine Life!


The second factor is the reaction of moisture and curing agent to produce gas


Phenomenon: the filling machine will produce large bubbles after curing


1. The main agent has been used many times, and moisture is mixed in during the mixing process of each glue filling machine. It is also possible that the cover of the package is not tightly closed.


2. There is too much moisture in the filling product of the glue filling machine. It is recommended to preheat the product before pouring.


3. The surface of the mixture of the main agent and curing agent reacts with moisture in the surrounding air. We choose to cure in a dry environment or put it in a higher temperature oven.


4. The liquid mixture of main agent and curing agent may contact other chemicals (such as solvent, film remover, varnish, glue, etc.) before curing.


To sum up, these factors are responsible for a large number of glue pouring machines after curing. We need to pay attention to avoid similar situations when pouring glue. If you want to know more about the pouring machine, please pay attention to the jingrenda precision official website!
