摘要： A thermoforming process capable of coining and flowing material is provided, such as for making a thermoformed energy absorber for self-attachment to a vehicle bumper beam. The energy absorber includes a thermoplastic sheet with first thickness shaped by a thermoforming process to include a base and lobes configured to absorb energy. The sheet further has integrally formed attachments with solid heads formed from material flowed from adjacent areas into the attachment during the thermoforming process. Many other structures can be formed, such as ringed ridges, thinned regions, snap-attachments, hooks, living hinges, bosses, and the like. The present invention further includes an apparatus and a method for accomplishing the above, such as a heater for heating the sheet, and a die for stretching and shaping the sheet, where heated material is flowed by opposing coining die components to form selectively-shaped 3D structures.

摘要： A thermoformed product formed during a thermoforming process includes a thermoformed sheet of polymeric material having front and rear surfaces defining a thickness, and having a first section thermoformed to include a non-planar three-dimensional useful structure and at least one second section. Each of the at least one second sections have a first area of reduced thickness and have a second area including attachment structure, with the attachment structure being formed in part by material extruded from the first area into the attachment structure while the polymeric material of the sheet is hot during the thermoforming process.
