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 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.
Last week, Tancredo told us that their engineers approved both batches of hydraulic manifold samples of AAK. The equipment installed with AAK hydraulic manifolds has been used for almost a year, and have no complaints. Why AAK hydraulic manifold can achieve reliable functions and guaranteed performance? It lies in 3 details of manufacturing quality:
1. The processing of hydraulic manifold block can ensure that the parallelism of two corresponding surfaces is less than 0.03mm, and the non perpendicularity of two adjacent surfaces is less than 0.05mm. The intersected drilling holes are designed according to the oil flow direction, and do not follow the trend to avoid eddy current or shock vibration.
2. Strictly control the treatment, deburring, rust removal, deoxidized skin removal, and cleaning of sharp edges of the hydraulic manifolds. Do not use traditional manual work.
3. Hydraulic manifold inspection, involves pressure test, function test, and is 100% fully inspected.
