Rotary die cutting equipment

Die-cutting is a process that converts a material by cutting and shearing it into different shapes and designs. It uses materials that are dynamic and can be customized. This process is done for a wide range of materials and is widely used by many manufacturing firms.

There are many types of die-cutting processes like flatbed die cutting, laser die cutting, and rotary die cutting. As the name speaks, the flatbed die cutting uses a flatbed die and press while the laser die cutting uses a high-speed laser cutting machine. Lastly, the rotary die cutting equipment uses a cylindrical rotary die and a rotary press. It depends on the needs and the die-cutting materials and size, that determines the die cutting machine to be used.

The rotary die cutting equipment runs smoothly at a specific capacity. The machine has a particular configuration and setting. As said earlier, this type of die cutting machine uses custom-designed cylindrical dies, which is attached to the rotary press, and then the material is converted. A flexible material, which is usually in the form of a roll or sheet, is put into the press die cutting machine. It holds the cutting die cylinder and anvil cylinder that rotates in opposite directions. This reverse rotary cutting die acts like a machine and executes the cutting procedure.

In a rotary machine, you can get the desired cuts and slits. It is essential that in the rotary die cutting machines, both the cylinders and the web run at the same speed. Only after this, the die cuts are properly in parallel to each other and ends up in a uniform material. The machines often use motors to have better accuracy and uniformity.

Rotary die cutting machine can be used for materials like metal, foam, fabric, plastic, paper, and laminates. The type of material that intends to get converted decides the configuration and settings of the rotary die cutting machine. The type of material also plays a role in the design of the rotary cutting die. The thickness of the material and the flexibility also determine the height of the cutting blade and the optimum angle it should be. If you want to cut a thick material, the blade height needs to be higher, and the angle needs to be steeper, while in the thin materials, the height needs to be low, and so is the angle. If the material is multi-layered, there may be different adjustments to the heights and angles.

The material properties determine the type of rotary die, too, such as a flexible rotary die should be used or a solid rotary die. Thinner materials may use flexible or solid die while thicker use solid rotary die only.
