High-precision stamping processing with a focus on appearance!
At Koike Seiko Co., Ltd., we primarily focus on products made through precision press processing, particularly in the manufacturing of motor-related parts, OA-related parts, home appliance-related parts, and low-voltage-related parts, utilizing our expertise in drawing processing technology. Our specialty, "drawing processing," includes round drawing, square drawing, and irregular drawing. In particular, motor parts and hard disk parts that utilize round drawing are produced with precision standards of roundness within 5µ, coaxiality within 15µ, and balance within 10mg/cm, along with a commitment to the appearance (mirror finish) achieved through the drawing process. [Achievements] ■ Drawing processing of small stepping motor parts ■ Processed products of vibration motor parts ■ Drawing processed products of motor cover parts ■ Drawing processed products of connector parts ■ Drawing processed products of parts for 3.5-inch HDDs *For more details, please refer to our catalog or feel free to contact us.

basic information
【Processing Examples】 ■ Deep drawing of small stepping motor parts - For case-type products, the inner pole teeth are drawn in, and the outer circumference is drawn up. - After that, the shape of the pole teeth is formed by punching. ■ Processed products of vibration motor parts - For case-type products, the blank size is determined and drawn in one go. - For flat-type products, the thickness of the bottom is reduced through crushing processing, and a barrelling process is applied to the center. ■ Deep drawing of motor cover parts - The maximum size for round shape drawing with progressive dies is an outer diameter of φ35 or less and a drawing height of 20mm or less. - The maximum for single processing is limited by the equipment, with a maximum processing range within the pressure capacity of a 200TON press. - Deep drawing improves dimensional stability and finishes the appearance beautifully by handling the material. ■ Deep drawing of connector parts - The drawn part serves as the cover for the connector terminal, and the flange of the drawing is attached to the equipment. - Increase the die radius to reduce the amount of reduction. ■ Deep drawing of parts for 3.5-inch HDD - Pursue roundness and coaxiality precision through drawing that handles about 10% of the material thickness. - Rotate the product and manage the rotational runout caused by uneven thickness in drawing using a balance measuring device. *For more details, please refer to the catalog or feel free to contact us.
