AAK Hydraulic manifolds, 450MPa pressure resistance and ultra light weight

Isacco compared more than 10 hydraulic manifold factories. No manufacturer can
achieve the light hydraulic manifold with pressure resistance of 450MPa, and
AAK successfully completed the sample at one time. At the beginning of last
year, Isacco’s company developed an aviation hydraulic power unit, which is
the first time for SICMI company to try aviation equipment. Their customer
specially mentioned that the hydraulic manifold should withstand a high
pressure of more than 450MPa, especially pay attention to the weight of the
hydraulic valve block, because the aviation equipment has strict restrictions
on the weight of each part, and this hydraulic valve block must be made of
ultra light aluminum.

Isacco got the purchase list of hydraulic manifolds. First, he contacted the
current hydraulic manifold manufacturers. Only 3 manufacturers agreed to try
samples, and other manufacturers gave up. 1 month later, Isacco successively
received the hydraulic manifold samples. After installation and commissioning,
the high pressure resistance test of the hydraulic manifolds from 2 factories
failed. Although the pressure resistance test of the hydraulic manifold of the
3rd factory was successful, its weight was more than 20% higher. Isacco asked
the 3rd hydraulic manifold manufacturer to re-sample, but the manufacturer
advised that 7075 aviation aluminum is the lightest material. Isacco had to
look for new hydraulic manifold manufacturers again. He contacted more than 10
hydraulic manifold manufacturers successively, but there was basically no
feedback.

Isacco left a message on AAK website: Does AAK have lighter materials than 7075
aviation aluminum to produce hydraulic valve blocks? With this message, we
understand that this hydraulic manifold should be used in aviation, not only
light, but also resistant to high pressure above 450MPa. According to the
hydraulic manifold drawings and working condition requirements provided by
Isacco, frankly speaking, our engineers have no ideas, because 7075 aviation
aluminum is the preferred material for our production of high-pressure
hydraulic valve blocks.

AAK hydraulic valve just likes the development instructions given by customers,
which are not involved in AAK before. We are willing to cooperate with Isacco
to crack a hard nut of this hydraulic manifold. AAK spent more than 2 months
comparing aluminum materials for 12 times and selecting a material lighter than
7075 aviation aluminum after trying samples for 3 times. Isacco received AAK
hydraulic manifolds and conducted pressure test. One week later, Isacco asked
about the production time of 600 hydraulic manifolds and told us that AAK was
the only hydraulic manifold manufacturer that passed the test, with a pressure
of 450Mpa and a weight that met the requirements.

Why only AAK can achieve hydraulic manifolds with high pressure resistance and
light weight?
1.AAK hydraulic valve has an engineer who has worked in the Shanghai factory of
Germany HAWE for 11 years and has unique experience in high pressure
resistance.
2.AAK has material engineers who is specially responsible for screening,
comparison, testing and docking with the Research Institute.
3.This material is independently developed in China, a patented high-strength
multi-element microalloyed cast aluminum alloy. It has light texture, strength
up to 480-540Mpa and hardness ≥ HB140. It is the preferred material for the
core components of aviation equipment.

Last week, Isacco privately informed that the customer has a very good sales
and would place a big order again. His boss was very satisfied with his last
procurement performance. After working for 3 years, he was finally promoted to
procurement manager.

AAK hydraulic manifolds, can be used in aviation, you can also have a small
try!
