It can obtain the relative precision forging correctly shape and higher. And then castiron in the mold cavity, after curing the shell off, can obtain the precision manufacturingproducts. In a layer of wax brush liquid resistance of sand material at high temperature.To get enough after the thickness of dry, then
Garwin, the wax melted away, and blank consistent needed cavity. Precision forging is a forging method of the conventional forging process of. And then casting casting wax,obtain the original wax. The more common approach is: first for a blank (stay
Margin is very small or no allowance) electrode, and then use the electrode erosionmodule in detail, forming a cavity.
