摘要： A mobile molding system, comprising a vehicle and one or more molds arranged on the vehicle configured for receiving one or more expandable nonwoven substrates, heating said one or more expandable nonwoven substrates so as to cause said one or more expandable nonwoven substrates to expand and fill the one or more molds with one or more expanded nonwoven containing articles of three dimensional shape, and releasing said one or more expanded nonwoven containing articles of three dimensional shape from the one or more molds is provided. Methods for manufacturing three dimensional objects using the mobile molding system are also provided.

摘要： A three-dimensional component is produced in a simplified molding operation. Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. Boards can be formed by laminating two or more blanks together and/or by laminating the blanks with other materials, including non-expendable materials. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. In addition, the boards or blanks may be cut to create desired shapes of parts that can be placed in the mold.
