The invention discloses a manufacturing method of a vehicle body side wall edge beam. The side wall edge beam comprises a side wall edge beam body, an edge beam flange and a mounting support. The manufacturing method of the vehicle body side wall edge beam comprises the following steps that the side wall edge beam body and the edge beam flange are formed by SMC compression molding; the mounting support is formed by injection molding; and the side wall edge beam body, the edge beam flange and the mounting support are bonded and connected. According to the manufacturing method of the vehicle body side wall edge beam, the side wall edge beam body can be selectively formed by high-strength and high-performance SMC composite materials, and the obtained side wall edge beam body is light in weight and has better size control capacity. Meanwhile, the compression molding is simple in process and low in cost, the side wall edge beam can achieve integral type supply and easy convenient assembly on line, compared with a traditional automobile side wall edge beam, welding and assembling procedures can be reduced, and better appearance molding quality and appearance processing conditions are achieved.

    本发明公开了一种车身侧围边梁的制作方法,侧围边梁包括侧围边梁本体、边梁翻边以及安装支架,制作方法包括:侧围边梁本体和边梁翻边采用SMC模压成型;安装支架采用注塑成型;将侧围边梁主体、边梁翻边以及安装支架粘接相连。本发明实施例的车身侧围边梁的制作方法,使得侧围边梁主体可采选用高强度、高性能的SMC复合材料成型,获得的侧围边梁主体的质量轻且具有更好的控制尺寸能力。同时,模压成型工艺简单,成本低,侧围边梁可实现整体式供货线上装配,相较于传统汽车,可减少焊接、装配工序,且具有更好的外观成型和外观处理条件。
