The materials, as well as the machinery, are developed in-house!

Actually, YKK develops everything in-house, from zipper-making machinery to the materials.
By using YKK-built machinery to make zippers at factories around the world,
it’s possible to achieve the same product quality.

YKK develops materials as well!

For example, we develop optimal materials for zippers, such as metal, fiber, and plastic.

YKK develops and builds the production machinery, too!

We also undertake development of machinery and equipment and the manufacture of mechanical components, supplying specialized machinery to factories both in Japan and overseas.
