There are proven results for thrust washers with a donut shape and an inner diameter of 0.65mm!
Manufacturing thrust washers and washers that contribute to the improvement of durability in areas involving rotational motion, such as optical devices and motor-related components.
Our group company manufactures washers used for screw fastening and sealing in various industries, with a particular focus on producing thrust washers suitable for sliding parts that undergo rotational motion, such as bearings. We manufacture these using low-friction materials like PS (polyslider) and POM through punching and press processing, which not only enhances sliding performance but also helps reduce noise and improve the durability of moving parts. If you have any concerns regarding the sliding parts of miniaturized components due to product downsizing and weight reduction, please feel free to consult us. We have experience with donut-shaped washers with inner diameters ranging from 0.65mm to 40.7mm. We can also accommodate special shapes, such as cut washers. Please inquire for details about the molds we possess. ● We have a proven track record with various resins and metals. ● We have dedicated equipment for washer punching and own over 800 molds. ● Special shapes (such as cut washers) are also possible.
