From creases to curves

Cardboard is a rigid material that is difficult to work with. For example, bending it can be quite an ordeal. Ring binders have to open smoothly, and boxes often need to consist of a single piece of cardboard. We have various techniques for folding cardboard and creating sharp angles. Depending on the final product and its requirements, we chose either creasing or scoring. We can also use grooving or milling.


Creasing refers to reshaping the cardboard along straight lines without cutting through it. This process allows us to fold cardboard to create products like covers and ring binders. In fact, using multiple crease lines close to one another even allows us to create curves in cardboard.


Scoring (also called slitting) is similar to creasing, except that it involves making small incisions in the cardboard. These incisions allow for sharper folds than with creasing.

Crease punching

Crease punching is used to equip a single piece of cardboard with two creases and a binder mechanism in one go. As such, this technique is mostly used to make ring binders. You simply feed cardboard into the machine at the front, and a fully operational ring binder will come out at the back.

Crease punching

Single cover sheets are fed into the machine. The machine then creates the creases and installs the mechanism. The end result is a fully operational ring binder.
