Packaging-Type Vacuum-Forming Composite Board Welded By Ultrasonic Welding

摘要

A packing-type vacuum-forming composite board welded by ultrasonic welding includes a plastic surface plate, a plastic bottom plate and filling materials packed between the plastic surface plate and the plastic bottom plate. The edge of the plastic surface plate overlaps the edge of plastic bottom plate, wherein a welding rod made of plastic is arranged along the edge at the overlapped joint region between the plastic surface plate and the plastic bottom plate. The welding rod is connected to the plastic surface plate and the plastic bottom plate by ultrasonic welding.
