Competitive Advantage:
The heavy forging is manufactured by large scale stated enterprise. Advanced technical process from smelting steel to forging and heat treat guarantees the product quality. Closed relationship with several famous stated enterprises guarantee "in-time delivery" and competitive price.
Excellent product quality and service, competitive price, "in-time" delivery.

Process procedure:

Forging process flow quality control:

Raw material steel ingot into warehouse(test the chemical content)
Cutting→ Heating(Furnace temperature test)
Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)
Machining→ Inspection(UT,MT,Visual dimension, hardness)
QT→ Inspection(UT, mechanical properties, hardness, grain size)
Finish machining→ Inspection (dimension)
Packing and Marking(steel stamp, mark)→ Storage Shipment

Competitive Advantage:
