blow forming

The key technique of air pressure forming process to produce accordion folded boot for vehicle, that the ratio of the diameter to length was 50∶250, was summarized.

对径长比为50∶250的车用波形防护胶套的模腔—气压成型工艺的技术要点进行了总结,并对波形防护胶套的抗老化、抗龟裂、提高耐疲劳性能进行了实用探讨。

In this paper,the molding methods of air pushing clamp plate and air compact formed clamp plate were used to improve the compact homogeneity of molding sand.

本文利用气冲压板冲击、气冲成型压板冲击等紧实方法 ,对气冲紧实的匀实性进行了改进研究。
