针对发动机尾管内衬经模压成型后经常出现不同程度的裂纹缺陷，通过对模压预混料的质量指标、成型过程中的温度和升温速率等主要因素的分析与控制，发现裂纹的产生是多种因素综合作用的结果。通过对成型工艺过程中各因素的加强控制，可以避免裂纹缺陷的产生。

Aiming at the crack usually found at the surface of the tailpipe nozzle insert of some SRM during moulding pressing, the forming reasons are analyzed and controlled by target of quality, temperature and heating rate. Crack is the result of comprehensive shaping of many factors. Strengthening various factors in the process of molding process control can avoid the generation of crack defects.
