| Message: | The valve spool hardness of AAK hydraulic flow valves reached 65HRC, the German customer Felix was impressed after receiving the first batch of shipments. Last week, he placed a reorder for 9,600 hydraulic flow valves, with a total value of more than 60,000 US dollars, and regarded AAK as his preferred supplier for hydraulic valve purchasing in China.
In the hydraulic valve industry, more and more hydraulic valve manufacturers focus on homogeneous hydraulic valves, resulting in a decline in the level of hydraulic valve material selection and material reprocessing technology. Many hydraulic valve manufacturers think that their valve spool hardness meets the standard, but problems come out when they make samples or run production. The reason why most of hydraulic valve manufacturers can not solve the hardness problem well, mainly is: 1) without professional and systematic material knowledge, don't know how to choose the most suitable alloy steel material. 2) In the heat treatment of materials, most of them are led by the processing plants, mainly because the heat treatment is outward processing, and 20% of the outward processing is to change a place with one shot, and the hardness can not be guaranteed at all.
Before the first cooperation with AAK, Felix consulted no less than 30 hydraulic valve manufacturers for the hydraulic flow valve with 65HRC valve spool hardness within 1 month. Only 2 said that 58HRC was the limit they can achieve. As for the other hydraulic valve manufacturers, no any feedback at all. Felix was extremely disappointed.
When browsing the B2B website, Felix accidentally encountered an article about AAK HYDRAULIC VALVE. The article mentioned that 30 factories could not make the valve spool with a hardness of 65HRC, but AAK HYDRAULIC VALVE had already achieved in mass production, which made him curious about how the AAK HYDRAULIC VALVE can be different. |
