Integrated hydraulic Manifold system (IHMS) offers many advantages including reduced connectors, size and complexity, and enhanced flexibility for installation and maintenance. It provides a cleaner, leak-free, less vibrant and more reliable solution to difficult machine control system problems. So it is widely used in such fields as mechanism, metallurgy, forging, aviation, space flight, shipping and so on. As the key component of IHS, hydraulic manifold block (HMB) is still difficult to be designed in fac...
