For watches that are waterproof throughout, the charging station is also an important location that needs to be tested for waterproofing.This time, Hirays shows you some detailed pictures of the charging pile on the back case of the watch.I hope you all know more about the waterproofing of watches. 

The charging pile of the watch is an electromagnetic point, and there is usually a small rubber ring inside to seal it. If the seal is not good, water will enter the watch through the gap in the rubber ring and damage the watch.

The sealing test method used by Hirays Technology is to directly seal the two charging piles with sealing rings. When the upper and lower molds are pressed together, the internal space formed by the sealing rings is inflated. If there is air leakage in the charging pile, the compressed air we fill into the sealed space will leak to the outside through the charging pile, and the pressure in the sealed space will become smaller. Otherwise, the sealing will be good.
