With over 40 years of experience in manufacturing and technology through continual improvements on quality, NAK has secured its position on the global OE market and also became one of the top leading manufacturers of sealing products with collaboration and distribution networks spread throughout the world. NAK's seals are being used in a wide range of industrial sectors including Automotive, Industrial, Hydraulic & Pneumatic, Construction and Mining Equipment.
StreamSyn Sealing Solution is our customized, high-performance seal development process. This process gives our customers freedom in design, because they are no longer restricted by the standard seals available.
NAK works with customers, partnering with them, to develop seals that best meet their needs. Through thorough communication, we take time to understand our customers’ needs in every stage, including seal selection, design, test, seal installation, and seal performance optimization. We work together to help improve the performance and value of the customers' products.
From its establishment in 1976, to the present, NAK founded a material research and development laboratory in 1994 to continuously upgrade the technology to meet the challenges of a changing industrial environment. The laboratory has independent research and development capabilities, including formula research and development, rubber mixing, physical property testing, rubber material analysis (including quality inspections), all of which can be done in the factory. NAK’s research and development laboratory has an ISO/IEC 17025: 2017 certification in 2021.
We provide a full range of our sealing solutions. We develop long term business partnerships with our customers by offering them consistent product quality, on-time service and expertise sharing. Our expertise in sealing technology and design engineering has led it to become one of the most customer responsive aftermarket sealing suppliers in the world.
NAK has been working on an advanced LEAN & Flexible Manufacturing System over the last decade. We provide OEM customers with small-volume large-variety production services with our own Cold Runner Injection Molding Technology, which results in higher product performance and higher customer satisfaction.
With more than 500 vulcanization machines in operating in our plant, NAK uses the SCADA system to control production processes by monitoring real-time data. This allows us to control and maintain efficiency, distribute data for more intelligent decision making, and quickly communicate system issues to help mitigate downtime. Thus, the system has not only been immensely satisfactory in operation but has helped streamline our processes.
NAK invested in automation and industry 4.0 to improve our overall services and products ensuring better consistency in our quality, lead time, and costs. Automation introduces benefits for both NAK and our customers. Thereby increasing the lifetime value of our customers and brand loyalty.
We provide professional matching tests between rubber and oils, functional tests and durability tests.
Whether it is for a new product under development or an existing project upgrade, you can use NAK seals without having to worry about potential leaks or seal failures.
NAK seals are sold worldwide and are being used in a wide range of industrial sectors including,
but not limited to, Automotive, Industrial, Agriculture, Construction and Mining Equipment.
Recently, we've successfully developed a new seal specialized for use in precision reducers
that require low torque for high machine efficiency.
