Belt Press Machine,Juice Pressing,Fruit and Vegetable Complete Production Line,Sterilization Machine Co., Ltd. , http://www.nsfoodmachine.com
Our company makes forged shaft, such as forged steel shaft, forged high speed transmission gear shafts, forged steel stem crank shaft, carbon steel forged drive shaft, forged drum shaft, hot forged shaft duplex stainless steel, alloy steel power forging axle, forged marine propeller shaft, drive forged steel step shaft and forged turbine rotor shaft.
We follow the strict smelting process: EF+LF + VD+VC, to guarantee the inside quality of the ingot is better.
When it comes to forging process, our forging engineers are very skilled and experienced, the simple  process for open die forging is :
Ingot→heating→ forging → Heat treatment (Normalizing+ tempering) → Inspection
→rough machining→UT → twice Heat treatment →finishing machining →Inspection
The forging process can create parts that are stronger than those manufactured by any other metalworking process.
