“The minimum thickness required to ensure that the compressed component meets the design specifications after molding” refers to the minimum thickness necessary for the component to satisfy the requirements regarding strength, stiffness, and service life. The relationship between this thickness and other thickness values can be understood as follows: 1) Relationship with the designed thickness: The minimum molding thickness should not be less than the designed thickness. At the junctions between the shell and the fittings, in addition to considering the designed thickness of the shell, it is also necessary to take into account the reinforcement thickness required to strengthen those areas; this value represents the minimum thickness needed to meet the strength requirements of the component； 2) Relationship with nominal thickness and effective thickness: Given the nominal thickness of the component, the maximum possible value of the minimum formability thickness is the nominal thickness minus the amount of thinning due to processing, that is, the effective thickness plus the corrosion allowance ； 3) When determining the thickness of the steel, the manufacturing unit should rely on the minimum forming thickness specified by the designer, and take into account both the design roundness and the machining allowance based on its own manufacturing experience, in order to reduce waste caused by \"secondary rounding\".
