With the rapid development of industrial , sealing materials are required to face higher pressure, higher temperature, faster speed and worse lubrication problems. Therefore, it is extremely important to select appropriate sealing materials and sealing structure reduction for different application environments.
Kelong realized that this required a transformation from a provider of standard seals to one that could meet any customer's needs. We need to fully understand our customers' requirement and provide them with more complete services.
Our company adopts the equipment and production technology of DMH from Austria for the production of sealing line.
The main production process includes:
1. Rubber refining
2. Vulcanization
3. Cutting
4. trimming
5. Quality control
6. Warehouse
7. Packing
We have 3 hydraulic hose production lines, the production line has 619 sets of equipment imported from Italy, with an annual output of more than 15 million meters of various types of high-pressure hoses.
The main production process includes:
1. Rubber refining
2. Steel wire combining
3. Braiding/winding
4. Mold release
5. Pressure test
6. Hose Crimping
7. Packing
At the same time, we have also developed and implemented the project of complete sets of moving equipment for underground coal mines, and our main products are WC80Y, WC50Y, WC25E, WC60Y frame-type longwall chock haulers and new energy explosion-proof trackless rubber-longwall chock haulers.
