Abstract:
1. A hard drive comprising: an injection molded polymeric top cover ; the top cover comprising a body portion encasing a hard drive mechanism and a flange portion; said flange portion contacting an elastomeric seal element squeezed against a corresponding flange on each side edge of a base member of the hard drive by a plurality of pressure application means; said flange portion having an injection molded polymer and a convex shape contour metallic reinforcement portion embedded within said injection molded polymer and extended along a longitudinal direction of said flange portion such that vibrational energy is transmitted to the elastomeric seal element, said metallic reinforcement portion having a plurality of apertures for passage of said injection molded polymer to create rivet-like securing features, thereby preventing delamination of the metallic reinforcement portion from adjacent injection molded polymer during pressure application to the elastomeric seal element; whereby the pressure on said elastomeric seal element is maintained without viscoelastic relaxation of the flange portion.
