NNK brand takes you to find out the answer.
Due to the special working environment, the oil seal has relatively high requirements on its sealing performance, temperature resistance, wear resistance and pressure resistance, so as to ensure its adaptability to different working environments. Therefore, oil seal products should have higher requirements in terms of appearance and material. A good oil seal product is not only reflected in product performance, but also in terms of packaging and quality inspection and after-sales service. Therefore, if you want to make a good oil seal, you must start from these points. For these problems, NOK-CN factory does this:
Product oil seal metal shell by our self
If you want the product to have strong pressure resistance, you must start with the metal skeleton. The oil seal frame must be thick enough to support the entire oil seal to ensure its service life. Product oil seal metal shell by our self. Our shells are fully treated to prevent rust and increase the adhesion. After soaking in the solution prepared by us for many times, they are dried and completed under precise temperature control.
Use the best raw materials
If you want to improve the wear resistance and temperature resistance, it depends on the rubber. We have been committed to using the best raw materials, all from imports. Regarding some common materials such as nitrile(NBR) rubber, fluororubber(FKM), hydrogenated nitrile rubber, and silicone rubber, NNK is also actively working on material development. Moreover, it also uses its own blending technology to carry out polytetrafluoroethylene production at the same time. The development and improvement of engineering plastics such as resin, polyamide (nylon) resin, etc., achieve quality assurance through the improvement of materials.
Better Machines More Professional Vulcanization
Then there is vulcanization molding. Our NOK-CN factory vulcanization process is very mature. Our products have a long vulcanization time and higher performance. And our machines are replaced regularly, and we have been pursuing the best quality.
High-precision quality inspection
We refurbish the produced products and add springs to ensure tightness.

After strict quality control, we continue to improve our product process, research and development and service quality. Accurate handling of material properties and precise requirements for mold accuracy ensure a 100% product pass rate and enhance the core competitiveness of products.
Better packaging and service
The last is to do the packaging with heart, and deliver the goods to our customers in the fastest and best way.
After doing these points, not only will the brand's popularity become higher and higher, but customers will also trust our products more and more.
