The stem appears to be a straightforward press tool. An improperly designed, manufactured or used stem can result in stem breakage. Care must be taken to avoid this situation, as a stem break can be catastrophic, resulting in damage to the press, lost production time and possible injury. It is important to notify the manufacturer of the size of the press and its application, so that it can be properly designed to carry the high compressive loads. A site visit by a technician is recommended prior to use.
