A method for manufacturing a functional seamless soft bra-cup involves providing material sheets, heating, forming a first protective sheet, forming a second protective sheet, and finalizing a final product as the functional seamless soft bra-cup. A mold and a vacuum forming machine are first used to form plane material sheets into a first protective sheet and a second protective sheet. The first and second protective sheets are shaped according to a cavity of the mold. Functional material pieces are arranged between the first and second protective sheets. Then the mold and a heating device are used to bind the first and second protective sheets through high-frequency welding into the seamless soft bra-cup, which well fits a wearer's body profile and ensures wearing comfort. |

1. A method for manufacturing a functional seamless soft bra-cup, comprising the following steps:
providing material sheets, which includes a plurality of plane material sheet made of a thermoplastic material; heating the plane material sheets using a heating means, so as to make the plane material sheets become plastic; forming a first protective sheet by laying the plastic plane material sheets on a mold, which has a cavity, wherein the cavity includes therein a plurality of accommodating units, and is connected to a vacuum forming machine, so that when the vacuum forming machine generates vacuum suction, the plane material sheets are pulled inward the cavity and thus form the first protective sheet having a three-dimensional shape, in which a plurality of first receiving portions is formed on the first protective sheet by the accommodating units; forming a second protective sheet by laying another stack of said plastic plane material sheets on the mold, making the vacuum forming machine generate vacuum suction to pull the plane material sheets inward the cavity to form the second protective sheet having the same three-dimensional shape, in which a plurality of second receiving portions is formed on the second protective sheet by the accommodating units; and finalizing the functional seamless soft bra-cup by placing the first protective sheet on the mold, arranging a plurality of functional material pieces in the first receiving portions of the first protective sheet, placing the second protective sheet on the first protective sheet, such that the second protective sheet has the second receiving portions thereof covering at least the functional material pieces, and binding the first protective sheet and the second protective sheet together into the seamless soft bra-cup. |
