The encapsulation of washing machine control boards (computer boards) is one of the most typical applications of automated potting machine, directly impacting the reliability, safety, and lifespan of the washing machine.
Below, I will elaborate on the application of Automatic Glue Potting Machine in the encapsulation of washing machine control boards from the perspectives of “why encapsulation is needed,” “what adhesive to use,” “how to perform encapsulation,” and “the benefits of encapsulation.”
Inline vacuum potting machine: For example, the SEC-S400-ZL/ZHL ensures no air bubbles remain in the adhesive during potting through rapid vacuum extraction and high sealing performance, reducing leakage caused by bubbles.
Ⅱ.Commonly Used Potting Compounds
The main potting compounds used are two-component silicone potting compounds and epoxy resin potting compounds, each with its own strengths:
a.Two-component silicone potting compounds
● Main advantages: Good elasticity, resistance to high and low temperature impacts (-50℃~200℃), excellent vibration resistance, and repairability (the compound is soft and can be dug open for repair).
● Main disadvantages: Relatively weak adhesion, higher cost.
● Applicable scenarios: Mainstream choice. Especially suitable for environments with high vibration and large temperature differences, where ease of maintenance is required.
