Abstract

This invention relates to a method for integrally forming a gel pad to a rigid plate. A thin film is applied to at least one mold surface of a cavity of a perform mold. Gels are then filled into a recess of the cavity at a location corresponding to the film. After the gels are then cured to form a gel pad, an upper mold unit replaces the perform mold and causes the film to be adhered to at least one mold surface of the upper mold cavity of the upper mold unit along with the gels applied thereon. Another thin film is then applied to at least one mold surface of a cavity of a lower mold unit, followed by applying a fibril layer. Then, a foaming material is injected into a recess of the cavity of the lower mold unit at a location corresponding to the fibril layer, followed by applying another fibril layer. Then, prior to foaming of the foaming material, the upper mold unit is joined to the lower mold unit. The mold is then opened after foaming is complete such that the gel pad in the upper mold unit would be integrally formed with the rigid plate in the lower mold unit. The final structure is of a beautiful smooth appearance, provides sufficient joining strength, and prevents detachment.
