ABSTRACT:
The invention relates to a slider and a method of making the same. The slider comprises a bottom plate, an inner core, and a skin plate. The inner core has a bottom surface and a top surface, and is made of a foamed plastic. The bottom plate and the skin plate are bonded to the bottom surface and the top surface of the inner core, respectively, to form a laminate, and thus the inner core is sandwiched between the bottom plate and the skin plate. The bottom plate is a multi-layer structure, comprising a foamed plastic layer, an adhesive layer, a fabric layer, an ink layer, and a composite casting layer, which are laminated downward in order from the bottom surface of the inner core. The skin plate is also a multi-layer structure, comprising a foamed plastic layer, an adhesive layer, a film layer, a corona treatment layer and an ink layer, which are laminated upward in order from the top surface of the inner core. The invention provides a comfortable, lightweight and safely used slider, having the enhanced strength and toughness, with both a lower manufacturing cost and a simpler manufacturing process, whose design pattern is not apt to be worn off.
