A bat is created using efficient and automated techniques to apply layers of composite materials onto a mandrel. The system includes a plurality of rotating wrapping mechanisms binding stages. Each wrapping mechanism rotates along a central axis while a mandrel is driven through the axis. The rotational motion allows each wrapping mechanism to wrap one or more material strips along the outer surface of the mandrel. Between each wrapping layer, a binding material such as fusible thread may be applied to fuse wrapping layers together. The wrapping may be performed for the bat barrel and bat handle. Each mandrel may form two bats, and multiple mandrels can be connected together to maximize wrapping efficiency. The wrapped mandrels are separated into bat units, a resin transfer molding is performed, and the bats are completed.
