    • A system and method for fabricating the corner of a plastic window frame. The system includes a metal platen having opposed sides and that is for heating and melting adjacently disposed frame pieces by being inserted between the adjacently disposed frame pieces as the adjacently disposed frame pieces are brought into contact with respective opposed sides of the metal platen in order to melt adjacent surfaces of the adjacently disposed frame pieces. The adjacently disposed frame pieces, once heated and melted, are drawn together to form the corner of the vinyl window frame. A release layer is secured to the opposed sides of the metal platen and disposed between the respective adjacently disposed frame pieces and the opposed sides of the metal platen to prevent adherence between the metal platen and frame pieces. The release layer is comprised of a release film having a work area corresponding to an area where the adjacently disposed frame pieces are to be joined and a non-work area outside of the work area, and at least one adhesive strip is disposed within the non-work area for securing the release film to the metal platen while the work area is absent any adhesive between the release layer and the metal platen.
    • 一种用于制造塑料窗框的角部的系统和方法。 该系统包括具有相对侧面的金属压板,用于通过相邻设置的框架件插入相邻设置的框架件之间来加热和熔化相邻设置的框架件,因为相邻设置的框架件与金属压板的相应的相对侧接触,以便 熔化相邻布置的框架件的相邻表面。 一旦被加热和熔化的相邻设置的框架件被拉在一起以形成乙烯基窗框的拐角。 释放层被固定到金属压板的相对侧并且设置在各个相邻设置的框架件和金属压板的相对侧之间以防止金属压板和框架件之间的附着。 脱模层由具有对应于相邻设置的框架件要被接合的区域的工作区域和在工作区域外部的非工作区域的脱模膜组成,并且至少一个粘合带设置在非 - 用于将脱模膜固定到金属压板的工作区域,而工作区域在脱模层和金属压板之间不存在任何粘合剂。
