Evaluating Material Properties in Manufacturing to Enhance Efficiency

To produce oil seals and O-rings, various raw materials are blended to achieve the desired performance and physical properties. While raw materials come with data provided by manufacturers and finished products undergo a thorough evaluation, there is less readily available data on intermediate materials, those still in the processing stage before becoming final products. However, analyzing their properties is crucial for product development and manufacturing processes, as they play a key role in industrial production. For nearly 20 years, NOK has independently measured the processing characteristics of these intermediate materials. By expanding the scope of its evaluations, the company aims to improve production efficiency and strengthen its competitive edge.

Making the Invisible Visible: Analytical Techniques for Visualization at the Molecular Scale

NOK's strength lies in its technological capability to produce rubber with a wide range of properties that meet various societal needs. At the core of this capability is our advanced analytical technology. By visualizing and understanding rubber structure at a molecular scale, NOK develops safe and reliable products.

Applying Seal Technology to Meet Needs: Supporting Automobiles with NOK

Japan's first oil seal manufacturer, NOK provides high-performance, high-quality products to a wide range of industries, including automotive, construction machinery, agricultural machinery and electronics. Oil seals are used in engines, gears and other components that perform repetitive rotational or reciprocating motions. Their role is to prevent oil, liquids and gases from leaking while ensuring smooth rotational and reciprocating movement. Since decarbonization has become a critical theme for the automotive industry and other sectors, oil seals are also required to achieve higher performance than ever before. Leveraging its long-standing technical expertise, NOK is advancing research and development to ensure every oil seal has optimal functionality.
