He Advantages Of Investment Casting

- Aug 25, 2017 -

The castings are of high dimensional precision, generally can reach ct4-6 (sand casting is ct10~13, die-casting is ct5~7), of course, because of the complicated process process of the investment casting, there are many factors affecting the dimension precision of castings. For example, the shrinkage of the die, the deformation of the melt, the change of the line in the heating and cooling process of the shell, the shrinkage of the alloy and the deformation of the castings during the solidification process, the precision of the ordinary investment castings is higher, but the consistency still needs to be improved (using The consistency of the castings of high temperature wax should be improved a lot.
