Class 150 NPT, BSP and BSPT stainless steel castings are made of 304 and 316 materials, with good sealing and corrosion resistance, suitable for water supply, heating and various industrial systems. The products are produced through advanced silica sol precision casting process, with smooth surface and precise dimensions, which can ensure the tightness of installation connection and the stability of system operation. A variety of thread standards are available, and the size and interface form can be customized according to needs to meet the installation requirements of different regions. Keep inventory all year round and deliver on time. Through strict quality control process, the stability of the product in chemical composition and physical properties is ensured, which is suitable for a variety of application scenarios such as construction, municipal and chemical industries.

| 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 |
