The wax mold making process is a very important step in the process of investment casting, which is mainly used to make wax molds in investment casting, the specific role is as follows:
Manufacture of precision wax molds: The wax mold making process is carried out by injecting melted medium temperature wax into the molds, which is then cooled and solidified, resulting in precise wax molds that will be used as molds for subsequent casting;
Accurate Reproduction: The wax molding process reproduces the details and shapes of the prototype to ensure the precision and accuracy of the final graduation;
Preparation for investment casting: The wax mold making process provides the preparation for the subsequent investment casting and ensures high quality castings during the casting process;
In conclusion, the quality of control of the wax mold making process directly affects the quality of the wax mold and indirectly affects the quality of the final casting blanks, so it is a crucial link in the whole investment casting process.
