Tension Molding Manufacturer

The mold used for stretching is called a stretching mold, which is a tool for mass processing materials (metal or non-metal) into the required stampings. Stretching molds can be categorized into single-stroke deep drawing molds, compound molds, and progressive deep drawing molds based on their combinations. They can also be divided into single-action press stretching molds, double-action press stretching molds, and triple-action press stretching molds according to the stamping equipment used, with the main distinction being the different edge holding devices (elastic and rigid edge holding). Stretching molds can also be classified into first deep drawing molds and subsequent process deep drawing molds, with the main difference lying in the structure and positioning methods of the edge holding rings.
