How many unseen challenges lie behind a pellet mill that can operate stably for a long time?

Today, we'll take you inside Yulong's most mysterious testing center.

Let's see how Yulong controls testing standards

After the raw materials enter the factory

Spectroscopic material analysis and metallographic analysis will be performed.

Its component content and microstructure were tested.

Confirm whether it meets the standards

After rough machining of forgings or castings

Ultrasonic flaw detection will be performed again.

In subsequent work sections

All tests will continue to be strictly controlled.

Monitoring material stability

Pellet mill ring die 、 main shaft, etc.These core components

After they undergo vacuum quenching heat treatment or tempering heat treatment

They will be tested by a hardness tester.

to see if they meet the hardness standard.

Yulong's  coordinate measuring machine makes a stunning debut

The detection accuracy can be stably controlled at 1/3 of 0.01 millimeter.

It is specifically used for "micron-level inspection" of the core components of Yulong products.

Refined management of product quality

It is this series of controls

This ensures that every Yulong device is delivered to the customer in a more stable condition.
