Which of the following is a forming process used for papers and boards?

• A. Die cutting
• B. Welding
• C. Casting
• D. Extrusion

Answer: (A)

For papers and boards, forming processes are about shaping by cutting and punching sheet materials. Die cutting uses a specially shaped die and a press to punch out precise outlines from paper or thin cardboard, producing clean edges and complex shapes quickly. It’s ideal for packaging, cards, and labels because you can create many identical parts in one pass, and you can also add features like perforations or score lines for folding. Welding, casting, and extrusion are different kinds of processes: welding joins materials, casting involves pouring molten material into a mold, and extrusion forces material through a die to make long profiles—none of which are typical forming methods for paper or board.
