Message: | Tancredo comes from Italy, and he is an old hand in purchasing hydraulic manifolds. There are few hydraulic manifolds in cooperation with AAK. In the middle of last year, the first batch of hydraulic power units sold by their company, were complained of insufficient pressure supply and shock vibration 6 months after sales. During after sales service, it was found that the hydraulic cartridge valve of the hydraulic manifold was stuck, and the diameter of the intersecting hole of the valve block of the hydraulic manifold has deviation. The hydraulic manifold manufacturer advised that the residual burrs led to stuck, which may not be a large proportion. The hydraulic cartridge valves can be replaced for free, but he did not give reply about the diameter deviation at all. This after-sales service of hydraulic manifold is time-consuming and expensive. Tancredo realized that it was wrong to switch to this hydraulic manifold manufacturer, and was severely criticized by his boss.
Before ordering this hydraulic manifold, Tancredo contacted more than 10 hydraulic manifold manufacturers successively, and I also received his inquiry, but I was told that AAK hydraulic manifold had no advantage in price, so he gave the order to another manufacturer. After the customer complained, Tancredo came to me again and complained that the selected hydraulic manifold manufacturer was unreliable. I told him that for the production of hydraulic manifold, more attention needs to be paid to the details of manufacturing quality. The manufacturers who can produce hydraulic cartridge valves very well, may not be able to produce hydraulic manifolds well. Tancredo did not dare to try other hydraulic manifold manufacturers, and asked AAK to try 30 samples of the hydraulic manifold. 6 months later, he tried another 30 hydraulic manifolds. I understand Tancredo's operation. He is scared to fail again, and can not face his boss. |
