Fabrication Precess Management:

Equipment Improvement:

We focus on the development of manufacturing equipment, Join machines, Braiding machines, and Spiral machines. The key facilities have been iterated several times since we began to start our careers. 

Quality Tracking Card:

Quality tracking card is exclusively dedicated to recording the key parameter in the fabrication process, every indicator must be controlled within the tolerance range of standards.

Pressure test and package

Pressure Test:

When the batch of hydraulic hose is finished, it must be tested under 2 times the working pressure for more than 30 seconds. If it passes the exam, it can be packed and shipped out. If not, It will be cut into an unfixed dimension for sale.


Our hydraulic hoses are normally packed with plastic films or woven bags. 

Each package is labeled with detailed information on the product parameters, brand, name, diameter, length, and so on, products ID is included in case of checking.
