Customized solutions

Modular processes allow us to engineer a solution for almost every industrial application requiring free forged parts. Our modularity means flexibility, a wide range of options, faster delivery, and most important of all, competitiveness.

All our products and production process have been designed to assure excellent, reliable and long lasting unique mechanical performances, resulting in reduced operating costs and long life.

With a wide range of products and a significant experience gained in most industrial applications, we can also provide complete engineering recommendation for customers.

Forging process flow quality control:

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