Modern Technologies Applied for the Manufacturing of Hydraulic Manifolds Blocks

The paper provides a review of the scientific literature on modern technologies for manufacturing hydraulic blocks, focusing on additive manufacturing and laminated blocks versus conventional methods. The analysis highlights findings that show that laminated blocks can produce pressure drops lower by up to 50% compared to conventional blocks, next to weight decrease by up to 70%. Whether the additive manufacturing technology is applied, the weight can be reduced by up to 90% and the pressure drop can be lower by up to 44%, comparing to the results obtained for laminated blocks. This work examines the numerical and experimental results published last years, emphasizing the advantages and the limitations of each technology. By implementation of these two methods, more efficient design and production of hydraulic blocks can be achieved.
