Flexible Dies utilize top quality steel. Flexible dies are chemical milled and finished by CNC machining. There is no human touch to sharpen or adjust the blades. Blade height can be controlled to meet even the most strict tolerance needs. Blade to blade distance can also be controlled precisely within needed tolerances, to meet the growing stringent demands from the label printing industry. Mathias Die Flexible Dies will not rust and are built to last! For personal flexible die service please contact Mathias Die Company at 651-451-0105.
