| Message: | Alvis is from Norway and has been in contact with AAK for 1 year. There were some inquiries for hydraulic manifold blocks, but no actual order. It was not until December last year that the trust door was completely opened. It took him 6 months for a special hydraulic manifold block, but it didn't work. AAK solved the problem with the first sample.
A set of hydraulic manifold designed by Alvis will be exhibited in America. He selected a local hydraulic manifold block manufacturer that has cooperated for 3 years to try the sample, but the hydraulic system is unstable. The manufacturer advised that this hydraulic manifold block has many feedback oil circuits and control oil circuits, and the oil circuits is composed of small deep holes. The diameter of the damping hole is less than 1mm, and it is difficult to eliminate burrs for 100%, which may lead to blockage of the oil circuit. If the original design requirements of the hydraulic manifold block are not changed, the manufacturer would not be able to produce it. If the parameters are changed, the selling point of hydraulic manifold will be lost. Alvis is very distressed. He also tried to work with several other local hydraulic manifold manufacturers to make samples, but none of them is able to cooperate with him. In this way, 4 months have been wasted.
