1. Mold is always difficult at the beginning. Before implementing the process, it is necessary to draw accurate drawings or create samples, and then make the mold based on the drawings and samples.
2. The wax wax configuration heats up the formed wax to the desired level, then injects it into the insulation device, allowing it to stand and clean the water and impurities inside. Then, new wax is added until the volume meets our mold requirements. Next, the wax is injected into the previous mold, condensed and removed, and repaired to see if it meets the standards. If it does not meet the standards, the wax molding process is repeated when the waste is disposed of.
3. The shell making process involves passing the qualified wax mold through a transition layer slurry, drying, sealing, and then drying and dewaxing.
4. Casting involves roasting the front shell and casting it in two parts: solid solution and covering. After completion, the shell is cooled and peeled off, and then lifted, cut, and returned to the furnace for spectral analysis.
5. After cleaning and refurbishing, the steel material was subjected to steps such as soaking in hydrofluoric acid, sandblasting to remove the core, and shot blasting for secondary inspection. If any waste was found, the casting process was carried out again.
