    • In order to provide a durable and dimensionally stable union of hollow plastic sections, suitable, in particular, for economically producing small numbers of plastic window leaf frames and casements, two section ends (1, 1) are deformed while being joined in a straight line or with an angular offset, even when they have a complex cross-section. One union element (5) is designed as a shaping tool that generates an undercut in the section ends (1, 1) when joining them. The thickness of the walls of special cavities of the section (1) is designed to make them optimally deformable.
    • 为了提供一种耐用的,尺寸稳定的,特别是用于生产框架和塑料空心型材塑料星形连接的窗扇的小数目的经济eignende,根据提出的发明的两个型材的端部(1,1)具有复杂-俯视剖直线或角位移由 形成在接合过程相连接,其特征在于,在简档的端部接合时的连接元件(5),其为底切(1,1)形成产生成形工具,并且其中,所述型材(1)的特殊腔室的壁厚被设计为最佳的成形性。
