Since 2006, Song Cong Diesel Limited Company (DISOCO) has cooperated with Gohsyu Corporation (Japan) in the transfer of hot forging technology for crankshafts. DISOCO organizes crankshaft production based on a model combining hot forging and post-forging CNC machining for surface finishing, meeting the requirements of mass production for engine components.

Hot Forging of Crankshafts Based on Japanese Technology
At the forging workshop, DISOCO carries out hot forging of crankshafts in accordance with processes transferred from its Japanese partner.
Equipped with 1000T and 400T hot forging machines
Designed capacity: 7,200 tons/year

Post-Forging CNC Machining – Crankshaft Surface Finishing
After the hot forging process, crankshafts are transferred to the machining workshop for CNC machining to complete surface finishing.
Main machining processes include: Center machining, CNC turning, Machining of required surfaces

In-House Production Model – Forging and Machining Within the Same Plant

By implementing hot forging and post-forging CNC surface finishing within the same plant, DISOCO ensures smooth coordination between processes, maintains production schedule control, and meets the requirements of large-volume and stable orders.

With hot forging technology for crankshafts transferred from Japan and in-house CNC machining for surface finishing, DISOCO is confident in supplying crankshaft components for engines in mass production with stable quality.
