This paper presents an isothermal, one‐dimensional model predicting wall‐thickness profiles of vacuum‐ or pressure‐formed products. After formulating a set of simplifying assumptions theoretical analyses of forming into conical and truncated (deep and shallow) molds are presented and discussed. Fair agreement is found between previously reported experimental results and the proposed theoretical models.
