ABSTRACT:
A thermoforming manufacturing process is provided for creating modular three dimensional objects, particularly golf bags (10). The process includes preparatory steps of preparing a corresponding female mold member (42) for each of the golf bag segments (74) to be included, and preparing a laminate sheet material (44) having a fabric surface (46) to give the bag (10) the look and feel of a fabric of bag. Thermoforming steps including edge securing the sheet (44), softening with heat, drawing into the female mold member (42), cooling and removing the formed segment (74) are then performed. Finally, the segments (74) are assembled together to form the golf bag (10). Closed cell foam is the preferred thermoformable and shape retentive material with a woven stretchable fabric providing a preferred surface.
