Wiper inserts usually are less costly to produce than square-back wiper dies, because multiple wiper inserts can be manufactured from a thick-wall tube, and because the shorter and smaller inserts require less material. In addition, changeover time is shorter with an insert than with a square-back wiper die. However, initial setup requires the purchase of the steel holder, and the inserts must be replaced and disposed of more often than the square-back wiper die.
