1. Mould Designing Strictly making 3D model based on customer’s drawing dimensions, and mastered the contractibility rate for all types of material. |
2. Wax Injection |

3. Assembly The patterns are attached to a central wax stick, called a sprue, to form a casting cluster or assembly. |
4. Shell Building |

5. Dewax At this point, all of the residual pattern and gating material is removed, and the ceramic mold remains. The mold is then preheated to a specific temperature and filled with molten metal, creating the metal casting. |
6. Mould Shell Roast: This process is to put the lost-wax shell into the roast furnace and make them harder. Heating the Mould shell before casting is also to ensure the better products surface texture. |

7. Smelting the Liquid Steel: Allocate the chemical composition and sampling before steel casting. |
8.Spectrochemistry Analysis Inspection on materials by spectrometer testing. |

9. Conventional Casting In the conventional process, the shell is filled with molten metal by gravity pouring. |
10. Cut Off The parts are cut away from the central sprue using a high speed friction saw. |

11.Heat Treating Carbon steel and low-alloy steel need normalizing and temper, oil-quenching, water-quenching and so on. We can set out different heat treatment method as per different requirement from customers. |
12. Polishing Polishing is to modify the out of flatness on casting head after casting cuttig and to modify the burring and splashings in the process of casting cycle. |

13. Inspection: Inspection of the mechanical properties, surface, internal quality, and to check if the rough dimension meet the drawing requirement for the prodcuts. |
14. Machining Cut the piece of raw material into a desired final shape and size. Now we have CNC, Lathe, milling machine, drilling machine, boring lathe and grinding machine. |

15.Quality Inspection: Quality inspection on the machining dimension. Mainly tools we use is like specialized gauge and callipers, mircocalliper,three-dimensional and so on. |
16. Storage and Delivery Efficiency of package goods delivery on time per your shipping requests. |
