Sometimes we often encounter enhanced nylon bubbles, then you know why the enhanced nylon bubbles will have bubbles?
Xiaobian give you talk about this enhanced nylon bubble causes analysis
The so-called enhanced nylon bubbles can be called a vacuum bubble, enhanced nylon bubble of gas is very thin is vacuum, so called vacuum bubble. In general, if the moment in the mold has been found in the presence of bubbles are gas interference problems.
Reinforcing the formation of nylon bubbles is due to insufficient filling of the reinforced nylon plastic or low pressure conditions.
Does not rule out the rapid cooling in the mold under the action, and the cavity angle of the fuel pull, resulting in loss of volume situation.
