Our service included the forging, process, heat treatment, finish machining, package, local logistics, customers clearance and maritime transport. We took the customer’s requirements as the principal thing, and pay attention on the products quality. |
Process procedure:
Forging process flow quality control:
- Raw material steel ingot into warehouse(test the chemical content)
- Cutting→ Heating(Furnace temperture test)
- Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)
- Machining→ Inspection(UT,MT,Visal diamention, hardness)
- QT→ Inspection(UT, mechanical properties, hardness, grain size)
- Finish machining→ Inspection (dimension)
- Packing and Marking(steel stamp, mark)→ Storage Shipment
