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（中）：
提供了能够铸造和流动材料的热成型工艺，例如用于制造用于自连接到车辆保险杠梁的热成型能量吸收器。 能量吸收器包括具有通过热成形工艺成形的第一厚度的热塑性片材，以包括被配置为吸收能量的基部和叶片。 片材还具有整体形成的附件，其中在热成型过程中，材料由从邻近区域流入附件的材料形成。 可以形成许多其他结构，例如环形脊，变薄区域，卡扣附件，钩子，活动铰链，凸台等。 本发明还包括用于实现上述目的的设备和方法，诸如用于加热片材的加热器以及用于拉伸和成形片材的模具，其中被加热的材料通过相对的压印模具部件流动以形成选择性成形的3D 结构。
