the air hole on bucket working can be divide into three different types

When split one bucket tooth pin and excavate bucket, we would find several air holes exist around the thermal center part, but also find the air hole exist in the nearly core cavity wall surface too, professional bucket tooth pin production supplier said these air hole can be divided into three different types, such as the separate type air hole, intrusive type air hole and reaction air hole, etc.

During the casting working pieces produced by shrinkage hole and shrinkage porosity process, it must separate lost of air gas during this processing period too, in the other words, the air holes is produced together with the shrinkage porosity and shrinkage hole process.

If the total air content in the alloy material is too heavy, or there has insert too must air gas into the liquid metal mold filling process, professional bucket tooth pin production supplier said both of the shrinkage porosity and shrinkage hole problem would be enhanced, so there would be more air hole exist in the bucket tooth pin and excavate bucket thermal part internal space.
