Can castings produced by Gravity Casting Machine avoid shrinkage?

   Although the use of gravity casting machines to produce castings is widely used in many industries and the castings produced are well received, shrinkage may occasionally occur in castings. The shrinkage of castings will cause dimensional differences, which manufacturers are eager to avoid. This physical and natural shrinkage cannot be avoided, but it can be improved.

       The main reason for the shrinkage of castings is the shrinkage of casting products caused by uneven wall thickness, heat dissipation, and solidification conditions during the casting process. Therefore, we can feed the shrinkage parts by enlarging the reserved size, changing the mold design or casting process, or setting up a special feeding system. During the casting process, improved processes can delay and even out the shrinkage of the casting.

 

       In the production of gravity casting machines, the shrinkage of castings can also be improved by lowering the pouring temperature during casting, extending the pouring time, increasing the shrinkage processing allowance, etc. Although the shrinkage of castings cannot be avoided, manufacturers should try to improve the shrinkage through the above measures to reduce the secondary processing of casting products, thereby reducing production costs.
