Gerrard is one of our Spanish hydraulic valve customers. Recently, he needs to purchase a batch of hydraulic valves with very high precision requirements, mainly for the hydraulic system of cranes. After visiting no less than 10 hydraulic valve manufacturers, but found none of them is able to make the hydraulic valve with inner hole accuracy error within +/- 1μm. After this Spanish customer visited AAK Hydraulic Valve, he signed an order of US$40,000 for hydraulic valve.
After visiting a hydraulic valve factory in Ningbo called Ketai, a technical staff inside mentioned to him that to reach this 1 μ M error of the internal hole accuracy requirements of the hydraulic valve, you may need to go to AAK Hydraulic Valve, they just bought a honing machine imported from the United States, for the 1μm accuracy error of the inner hole, they may be able to do it. Gerrard is some in doubt about this and got AAK Hydraulic Valve address and contact information from that staff.
Honing machine is a kind of grinding machine which has higher requirements on the accuracy of inner hole machining. It can guarantee the accuracy control of inner hole of hydraulic valve. At present, few hydraulic valves have such high accuracy requirements, so less than 5% of domestic manufacturers will choose to equip with honing machines made in the United States to produce hydraulic valves.
The next morning, we received an email from Gerrard, he wanted to visit our hydraulic valve factory. After knowing his requirements about the hydraulic valve, we welcomed him to visit our workshop. In the production workshop, we introduced him the performance and parameters of some machines in detail. At the same time, he also looked at the whole operation process of honing machine carefully. Finally, Gerrard asked if we could control the accuracy error of the inner hole of the hydraulic valve within +/- 1μm. Because we haven't done such a hydraulic valve before, we can't guarantee it. We can only analyze the specific products. Before leaving, Gerrard asked us to make hydraulic valve samples according to his design drawings, with special emphasis on the accuracy error of the inner hole of the hydraulic valve within 1μm.
After 15 days of sending out the sample of hydraulic valve, Gerrard signed a purchase contract for hydraulic valve with us for US$40,000. Now it has been 3 months since the shipment, out of my expectation, we received a re-order of hydraulic valves today. According to his email, the sales of these valves are getting better and better, and it is expected to re-peat the order 4-6 times a year. At the same time, we also received several design drafts of high precision hydraulic valves from his company.
AAK high precision hydraulic valve, customers have no better choice elsewhere, you should also try an order.
