Die cutting can be performed using several different methods, each suited to specific applications, materials, and production requirements. Here are the primary types of die-cutting:

This strategy uses a flatbed die-cutting press and steel rule dies. The material is placed on a flat surface, and the die is pressed onto the material using a hydraulic or mechanical press. This approach is ideal for thicker materials or larger production runs, commonly used for packaging, gaskets, and larger labels.
This type of die-cutting involves a cylindrical die on a rotary press. As the die rotates, it rolls over the material, which is fed through the machine on a conveyor belt, cutting it into the desired shape. Rotary die cutting is best for high-volume orders and continuous materials like tapes, textiles, and long rolls of paper or plastic.
Laser die-cutting uses a high-precision laser to burn or vaporize the material in the desired pattern. Controlled by computer software, it offers flexibility in design changes without the need for physical dies. This tactic is suitable for intricate designs and small production runs where setup time and cost for traditional dies are prohibitive commonly used for stickers, intricate paper designs, and prototypes.
Similar to laser cutting, digital die cutting uses a small blade to cut the material. The design is controlled digitally, which allows for easy adjustments and minimal setup. Ideal for prototypes, custom orders, and low to medium-volume production.
This approach uses a high-pressure stream of water, sometimes mixed with an abrasive substance, to cut through materials. The process does not generate heat, making it good for materials sensitive to high temperatures. This tactic is best suited for cutting thicker and harder materials such as metals, stone, and thick plastics.
Each type of die cutting offers unique advantages, depending on the specific requirements of the project, such as material type, thickness, production volume, and design.

Die cutting is an important part of the self-adhesive label manufacturing process, especially most rolls of self-adhesive labels need to be die-cut after printing. Flat knife is one of the mainstream die-cutting methods. What is the working principle for it?
Flat bed die cutting machine, is a die cutting way by flat
bed die. When flat bed die cutting machine works, there is a vertical movement
between the plate table and the platen. The material is pulled forward by the
traction motor. And when the material passes between the plate table and the
platen, the plate and the platen are pressed together. Die-cutting knife is affixed
to the platen to make contact with the surface of the material and cut off the
material.
