Abstract：

Aluminum teapot mouth has a complicated shape,which needs to be formed with complicated forming process.Cold hardening phenomena in shaping process can easily result in expanding split.By analyzing components and utilizing the characteristics of component forming process,the bulging die was designed combined with perforation technique which could largely prevent expanding split to promote productive efficiency and ensure quality.This design offers a certain reference value for the likewise products.
