Computer Hard Drive Gasket Material
Relaxation, Retained Energy, Firmness
The gasket between a computer’s hard drive case and its cover plate must provide a perfect seal because hard drives require dust-free and moisture-free environments. An effective seal requires an unbroken gasket bead with an optimized contact area, which is dependent upon a perfect balance between a gasket’s firmness and a gasket’s relaxation. Four gaskets were tested with the relaxation method to determine the firmness and retained energy over one minute of hold time. The data can be used to screen gaskets for their ability to create a proper seal.
