Introducing the machining of parts for 3.5-inch HDDs!
We would like to introduce our achievements in "drawing processing," specifically for "3.5-inch HDD components." This product is designed to pursue roundness and coaxiality precision through a drawing process that handles approximately 10% of the material thickness. Furthermore, we manage the rotational imbalance caused by uneven thickness in the drawing by using a balance measuring device. The drawing process places a significant burden on the mold parts, leading to rapid wear, so it is crucial to enhance durability. At Koike Seiko, we believe that a product should not just be functional in form; it should be crafted according to the characteristics and applications that meet our customers' needs. We manufacture without compromise, from the selection of mold materials to product precision. *For more details, please refer to the PDF document or feel free to contact us.
