How to deal with the problem of casting bubbles

Bubbles can be said to be one of the most common problems in castings in the die-casting industry, and once a bubble problem occurs in a casting, it is equivalent to scrapping the product. In order to avoid the generation of bubbles, Xiaobian will analyze the casting bubbles for you in detail~~Teach you 7 strokes to solve the problem of casting bubbles.

[defects]

Under the skin of the casting, the bubbles formed by the condensing of the gas gather may sometimes be broken, and there are two types of penetration and non-penetration.

[Corresponding measures]

1、The temperature probe tests the surface temperature of the mold and displays the value exceeding the specified range of the process. Reduce the mold surface temperature and increase the dwell time;

2、The flow of metal in the gate of the casting surface is significantly brighter than other parts. The reason for the high filling speed is that on the one hand, the injection speed of the device itself is high, and on the other hand, the inner gate may be too thin. Reduce the injection speed and increase the thickness of the ingate properly;
