摘　　要：为解决现有阴模真空覆合成形工序过多的问题,对热塑性聚烯烃弹性体(TPO)表皮的阴模真空覆合成形(IMGL)工艺流程进行了优化与应用,通过对比分析现有工序,提出了减少工序流程同时优化成形工艺设备及模具等新方案并实施应用。与现有的阴模真空覆合成形工艺流程相比,工序减少6道、生产场地节省35 m2,成形周期缩短15 s,胶水用量减少且胶水利用率提升至90%。In order to solve the existing problems of too many processes in the In-Mold Graining Lamination(IMGL)process,the IMGL process based on Thermoplastic Olefin(TPO)skin was optimized and applied in practice.Compared with the existing problem of too long processes,this paper proposed the reduction of some processes and optimization of the forming equipment and mold,which were put in production.Compared with the existing IMGL process flow chart,the new flow reduced 6 processes,saved 35 m2 production site,shortened the IMGL forming cycle by 15 s,reduced glue usage,and improved the utilization rate of glue by 90%.
