Production Flow
| Raw Material  | Choose One-Level ingot steel, inspect chemical element , confirm achieve requirements. |
| Forging | Heating to the specified time and temperature. Have two kinds forging harmmer open forging and die forging . |
| Heat Treatment | According Tensile,Yield, Hardness requirements, fully heating. Incloud A,N,Q,T, surface HT and local HT. |
| Machining | Equip horizontal lathe, vertical lathe, CNC lathe, CNC machining center, turning machine,boring machine, milling machine, grinder. Tolerance can hold +/-0.02mm, Â surface roughness can hole Ra0.8. Grindering geometric tolerance. |
| Inspect |
 Every products mad a test bar, used for test hardness and mechanical properties. All forging rough 100% UT inspect.  |
