Abstract
Embodiments herein relate to hollow profiles and methods of preparing the same for joining operations. A method herein can include placing a dam within a channel defined by the hollow profile, fitting a die block over an end of the channel, and injecting a flowable composition through an injection port into the channel. Another method can include defining a volume within a first member using at least one flow control device, filling the defined volume with a flowable polymeric composition, allowing the flowable polymeric composition to solidify to form a solid portion in the first member, and mechanically modifying the solid portion to define a joining surface suitable for joining to the second member. Other embodiments are also included herein.
