Product Design


▊Structure design

CSB-PEW® plastic flat spring is designed with a bump axial surface for the purpose of compensates the axial fitting and machining tolerance in addition to function as a normal washer. Therefore the operation mechanism could be more stable and with less noise.


▊Material design

CSB-PEW® plastic flat spring is made from the professional wear resistance material CSB-EPB13 which provides good wear resistance and excellent spring feature. At the same time, CSB could also provide the spring washer with high temperature (up to 250℃) material CSB-EPB5 and FDA approved material CSB-EPB5A.


▊Assembly design

In order to adjust the fitting clearance, a single flat spring is usually inserted. For bigger clearance adjustment, a group of flat springs combined with back to back or face to face is also a good solution. If a higher elastic characteristic is needed, piling the flat springs parallel and assembles into the required position.
