Your Basic Guide to Achieving the Best Results in Die Cutting and Creasing

March 13, 2020

Die-cutting and creasing operations are extremely important in processing cartons, folders, and other packaging materials. The elements needed to achieve the best results in die-cutting and creasing involve the right tools, correct machine settings, the appropriate type of materials, and the condition of the materials. The combinations of these elements can significantly alleviate your job in die cutting, creasing, and other operations needed for your business. 

Die cutting Operations

Die cutting is a process where a flat-bed die cutting machine is used to consistently mass-produce cut-out materials. A material that has a good cut is normally clean and doesn’t have any loose fibres and particles. The edges of this material are accurate and precise, making the overall manufacturing process of the material smooth and efficient.

All the cutting rules must have the same height to cut through the entire thickness of the paperboard across the die if you want to achieve the best die cut results. The nicks, which are produced by grinding a notch in the cutting rule, must be in line with the gripper force. If possible, the dimensions of nicks should be as small as possible. The flaps of a blank should be linked with another blank by placing two nicks as far as possible.

To avoid distorting the shape of your sheets or blanks, you must control the overall climate of your workstation. This control can keep the moisture content of your sheets or blanks unchanged. High moisture content can make your blanks tough to separate, while low moisture content can make your blanks instantly separate. Irregularities on moisture content and dimensional variations can cause misregister between your printed image, cuts, creases, and embossed impressions.

Creasing Operations

Creasing is a process where some parts of the material are weakened along well-defined folding lines. These folding lines act as hinges for folding packaging and other manufactured products. Folding a packaging material without any creasing can negatively affect the material’s quality and overall appearance.

Creasing operations are carried out through the use of a thin strip of steel with a round smooth edge and accurately groove cut in thin hard material. This material is also known as the make-ready, matrix, or counter-die. The creasing rule will push the material into the groove of the make-ready, which makes the permanent crease.

There are a lot of factors involved in making great creasing. Good creasing must consider the height and width of the creasing rule, the thickness of the make-ready, the groove width, the accuracy and hardness of the make-ready, and the pressure of the die-cutter. All these elements must go well with the predetermined material thickness and the intended direction of the creases
