Molding system for breathable thin-layer article and molding method thereof where the lamination layer can cover a first thin layer article thereon and extend into a plurality of breathable holes

A molding system for a breathable thin-layer article comprises a rotating device, a bottom unit, a lamination output device, and a vacuum extraction device. The rotating device includes a first support component that rotates about a first axis. The bottom unit includes a first thin-layer that can be driven to rotate by a rotating device and has a first thin-layer article with a plurality of breathable holes. The first thin-layer article has a first and a second surfaces opposite to each other, and the second surface is adjacent to the first support component. The lamination output device is arranged above the bottom unit, outputs a lamination layer in a casting manner, and directly covers the first thin-layer article thereon to form a second thin-layer article. The vacuum extraction device is adjacently installed to the bottom unit to evacuate air from the first surface to the second surface, so that when the lamination layer is covered on the first thin-layer article, it can extend into the breathable holes.
