摘要:
A method of producing a foamed part, in particular a car body attachment part for a motor vehicle, includes the following steps. A foaming tool is provided that includes a tool bottom part and a tool upper part. An outer skin is placed in the tool bottom part and an expandable material is applied. The foaming tool is closed, with at least one portion of the outer skin being located in a gap between the tool bottom part and the tool upper part. After the foaming process, during opening of the foaming tool, the outer skin is trimmed by the foaming tool itself. The invention further relates to a foaming tool for applying such a method.
摘要(中):
一种制造发泡部件的方法,特别是用于机动车辆的车身安装部件的方法包括以下步骤。 提供了包括工具底部和工具上部的发泡工具。 将外皮放置在工具底部,并施加可膨胀材料。 封闭发泡工具,外皮的至少一部分位于工具底部和工具上部之间的间隙中。 在发泡过程之后,在打开泡沫工具期间,外皮由发泡工具本身修剪。 本发明还涉及一种用于应用这种方法的发泡工具。
