| Step | Process Name | Description |
| 1 | Raw Material Preparation | Select stainless steel or brass; perform MTC & PMI inspection |
| 2 | Wax Pattern Making | Create precise wax models; assemble into wax trees (for investment casting) |
| 3 | Shell Building | Apply ceramic layers to build a strong mold shell |
| 4 | Dewaxing & Firing | Remove wax using steam; fire the shell at high temperatures |
| 5 | Metal Pouring (Casting) | Pour molten metal into shell molds; allow controlled cooling |
| 6 | Shell Removal & Cleaning | Break off ceramic shell; clean and sandblast or pickle the castings |
| 7 | CNC Machining & Threading | Precision machining, thread cutting (BSPT/NPT/BSPP) |
| 8 | Inspection | Perform dimensional, visual, thread, and optional PMI or pressure tests |
| 9 | Surface Treatment | Pickling, passivation, polishing or electroplating |
| 10 | Marking & Packaging | Laser/stamp marking; export packaging with labeling and protection |
