Common types of sheet metal tooling include dies, punches, press brakes, shears, and roll formers. Dies are often used for cutting, bending, and forming operations, while punches are used to create holes or other shapes in the metal. Press brakes are used for bending operations, shears for cutting, and roll formers for shaping long strips of metal into desired profiles.

Factors to consider include the type and thickness of the metal being used, the desired precision and complexity of the parts, production volume, available budget, and the capabilities of the manufacturing equipment. Additionally, factors such as tooling material, durability, and maintenance requirements should also be taken into account.

Well-designed sheet metal tooling solutions can improve efficiency by reducing setup times, minimizing material waste, and increasing production speeds. They can also enhance quality by ensuring accurate and consistent part dimensions, reducing defects, and allowing for tighter tolerances.
