The formation of vacuum bubbles is due to insufficient plastic injection or low pressure. Under the action of the rapid cooling of the mold, the fuel at the corner of the cavity is pulled, resulting in volume loss.

The gas in the bubble (vacuum bubble) is very thin and belongs to the vacuum bubble. Generally speaking, if bubbles are found at the moment of mold opening, it is a gas interference problem. The formation of vacuum bubbles is due to insufficient plastic injection or low pressure.
