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.
Advantage:
1.High-precision dimensional tolerance;
2.Excellent mechanical properties;
3.Produce different dimension based on customer’s requirements;
4.Advanced manufacture equipment and inspection devices;
5.Excellent technical personality;
6.Control the production procedure strictly;
7.Pay attention on the package protection;
8.Quality full service.
