Why use BuntingÂŽ Magnetic Cylinders and Flexible Dies?
We have invested in state-of-the-art precision machinery to manufacture our magnetic cylinders and flexible dies to meet or exceed OEM specifications. We have developed special techniques for our grinding process for our cylinders. This allows us to hold tighter tolerances than competitive cylinders. In fact, the runout tolerances on our Series cylinders are so precise (below 80 millionths of an inch). Behind all the equipment, and the craftsmanship, is a team of engineers and technicians dedicated to helping you find the best solution.
Magnetic Cylinders and Flexible Dies
As the world leader in producing the best magnetic cylinder, Bunting Magnetics Co. produces a wide variety of magnetic cylinders including magnetic die cutting cylinders, two-piece can printing cylinders, corrugated carton printing cylinders and more. Complementing our Printing line we also produce all types of flexible dies from simple designs to intricate die patterns.
