- Enclosed forging with opposed back-pressure added controls combined extrusion and simultaneously performs near-net shape forming for male and female hydraulic parts.
- The use of back-pressure tools makes enclosed forging the one with variable displacement, allowing the upper die to form casings by backward extrusion and the lower die to form bosses by forward extrusion.
- After forging, chip separation is performed and final properties are assigned by combining annealing, solution treatment, aging treatment, and sizing.
