1. A keyboard cover fabrication method, comprising steps of:
providing a metal sheet material; employing a compression molding technique to process said metal sheet material into a shaped metal component having a plurality of protrusions; and removing a top portion of each said protrusion of said shaped metal component, thereby forming a key board cover; wherein the compression molding technique comprises the steps of: providing a mold comprising a sealing die defining therein a sealing cavity and at least one inlet and a shape forming die defining therein a shape forming cavity; providing at least one heater for heating said mold; placing said metal sheet material in between said shape forming die and said sealing die of said mold; and connecting at least one fluid supply source to said inlet of said sealing die and then operating said fluid supply source to provide a high pressure fluid through said at least one inlet into said sealing cavity to give a fluid pressure to said metal sheet material, deforming said metal sheet material and forcing said metal sheet material against an inside wall of said shape forming cavity so that said metal sheet material is molded into a shaped metal component having a plurality of protrusions. |
