Forged chain sprocket wheel for marine engineering equipment
We are your partner when high mechanical stress has to be taken into account and the highest reliability under aggressive environmental or ambient conditions is required. From steel production to the completion of the forged product, we carry out every step in the production process. We take responsibility ourselves and ensure that our customers receive consistent quality assurance. We check and document the quality of our products at every point of the production chain. Our open-die forgings are characterised by the tightest tolerances and large dimensions. In our ultra-modern facilities, we manufacture forgings to drawing with a weight of up to 35 tons. We have many areas of expertise, including the production of impellers, shafts and discs, for compressors or turbines and components for fasteners, separators, pumps and valves in a pre-machined condition.

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)→ Rough Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→Semi finish teeth milling+drilling→Surface hardening treatment→ Hardness Inspection→ Finish machining teeth→Blasting and Painting→ Packing and Marking(steel stamp, mark)→ Storage Shipment
