Stretching molds are used for stretching operations, which are tools for mass processing materials (metal or non-metal) into the required stampings. Stretching molds can be categorized into various types based on their combinations, including single-stroke deep-drawing molds, compound molds, and progressive deep-drawing molds. They can also be distinguished by the stamping press used, such as single-motion press molds, double-motion press molds, and triple-motion press molds, with the main differentiating factor being the type of flanging device (elastic flanging and rigid flanging). Stretching molds can also be divided into initial deep-drawing molds and subsequent process deep-drawing molds, with the primary distinction lying in the structure and positioning of the flanging rings.
