关于IMG-L真空包覆仪表板高温起泡的解决方案

Solution of High Temperature Bubble of IMG-L Vacuum Coated Instrument Panel

以某车型真空成型包覆仪表板为研究对象,通过试验分析,指出仪表板受到100℃以上高温,持续30 min,可发生起泡不良,整车经暴晒,可达到该触发条件。对策着重研究增强胶水与骨架贴合强度的方向。经研究,可通过调整模具间隙、增强骨架排气性、增大骨架粗糙度方法增强贴合强度,达到解决起泡问题的目的。同时指出增加烘炉以100℃×30 min作为质检工序,可有效防止起泡不良品流出生产工序,为解决真空成型包覆工艺起泡难点课题提供参考。

With the vacuum formed and coated instrument panel of a vehicle as the research object, this article,through experimental analysis, indicated that the instrument panel blistered, and triggered the blistering condition after the vehicle was exposed to a high temperature of more than 100 ℃ for 30 minutes continuously. The research focused on enhancing the bonding strength of glue and skeleton as countermeasure. Through research, the bonding strength can be enhanced by adjusting the mold gap, enhancing the exhaust property of the skeleton, and increasing the roughness of the skeleton, so as to eliminate blistering. The article also pointed out that adding the oven with temperature of100 ℃ for 30 min as a quality control procedure can effectively prevent the blistering and defective products from flowing out of the production line, and provide a reference for solving the problem of blistering in the vacuum forming coating process.
