Detailed introduction of several common pouring methods for silica sol precision casting
Time：2025-04-07 /Hot：0
There are several casting methods for silica sol precision casting during the entire casting process. In the entire process of vacuum pump breathing casting, the silica sol precision casting will reasonably place its shell in the vacuum pump pouring box, and reasonably extract the vapor from the mold cavity according to the fine gaps in the shell during application.
Reasonable application of silica sol precision casting can enhance the filling of hydraulic press metal materials, copy the shape of the mold cavity, improve the precision of castings, and avoid the disadvantages of air holes and insufficient pouring.
Under the working pressure of silica sol precision casting, crystals are formed. When applied, the mold shell is reasonably placed in a working pressure tank for casting. After the product is completed, the pressure tank will be immediately closed. During application, high-pressure gas or rare gas will be filled into the tank to solidify the casting under working pressure, thereby expanding the relative density of the casting.
If silica sol precision casting is used with its hot molding force casting, it is a commonly used casting method throughout the entire application process. After the shell is removed from the roasting furnace, it is poured at high temperature.
