AAK Hydraulic Manifold Block 100% Burr Free, Alvis admired

Alvis is from Norway and has been in contact with AAK for 1 year. There were
some inquiries for hydraulic manifold blocks, but no actual order. It was not
until December last year that the trust door was completely opened. It took him
6 months for a special hydraulic manifold block, but it didn't work. AAK solved
the problem with the first sample.

A set of hydraulic manifold designed by Alvis will be exhibited in America. He
selected a local hydraulic manifold block manufacturer that has cooperated for
3 years to try the sample, but the hydraulic system is unstable. The
manufacturer advised that this hydraulic manifold block has many feedback oil
circuits and control oil circuits, and the oil circuits is composed of small
deep holes. The diameter of the damping hole is less than 1mm, and it is
difficult to eliminate burrs for 100%, which may lead to blockage of the oil
circuit. If the original design requirements of the hydraulic manifold block
are not changed, the manufacturer would not be able to produce it. If the
parameters are changed, the selling point of hydraulic manifold will be lost.
Alvis is very distressed. He also tried to work with several other local
hydraulic manifold manufacturers to make samples, but none of them is able to
cooperate with him. In this way, 4 months have been wasted.

Alvis wanted to try overseas hydraulic suppliers, and sent me an email.
According to his hydraulic manifold block drawing, our technical team analyzed
and discussed it, and concluded that if the original design was not improved,
the burr hazard would still exist. Alvis seemed to think that AAK is unable to
sample the hydraulic manifold block, so he did not have further contact with
us. 1 month later, he came back to us again to discuss this hydraulic manifold
block, and asked about our optimization plan. I realized that he was desperate,
and told him that AAK did not need to change the parameters of the hydraulic
manifold block, but only needed to increase the angle between the two planes
greater than 150 °, but the best degree still needed to be explored. Alvis
suddenly realized it and blamed me for not telling him earlier. I joked that he
didn't give me a chance to tell him.

After changing materials for 2 times, and adjusting the processing parameters
for 4 times, it was determined that 158 ° would be the best angle. After 30
days, 3 hydraulic manifold blocks were sent out. 3 weeks later, Alvis told us
that the hydraulic manifold was running stably, meeting the system
requirements, and we just need to wait for the good news of the exhibition. He
sighed that for this exhibition, he was in trepidation for 6 months, but did
not expect that the first sample of AAK was successful. In the future, AAK will
be his preferred supplier for hydraulic manifold blocks. This is also what I
said before. Whether customers buy your products or not is not because of your
poor price or long distance. The root cause is that the trust is not in place.

AAK hydraulic manifold blocks, in regards to deburring method, the following 3
points are critical:

1. Select materials with small elongation and deformation hardening index to
effectively suppress burr.
2. Optimize the valve body structure, the included angle between two planes
shall be greater than 150 °, and the best degree shall be tested continuously.
3. Use high-pressure solution jet to remove burrs, use solution to weaken the
magnetism of burrs, and then use the instantaneous impact force of liquid to
ensure that the hydraulic manifold block is 100% burr free.

AAK hydraulic manifold blocks, no burr, no pollution, no leakage, welcome to
try!
