Die-cutting is a manufacturing process used to cut shapes out of materials like paper, cardboard, or plastic. It involves using a sharp metal die, which is a mold that shapes the material when pressure is applied. This technique is commonly used in industries such as packaging, crafts, and printing to create precise shapes and designs efficiently. The die-cutting process can be done manually or with machines, depending on the scale of production. It allows for intricate designs and can produce multiple pieces at once, making it a cost-effective solution for creating custom items like greeting cards, stickers, and labels.
