Vacuum pads handle different materials by utilizing their design features and material properties to create an effective seal and grip. For cardboard, which is porous and rigid, vacuum pads with a larger surface area and softer materials are used to create a seal despite the surface irregularities. The softness allows the pad to conform to the texture, ensuring a better grip. For plastic, which is typically smooth and non-porous, vacuum pads with a firmer material can be used. The smooth surface allows for a strong seal with less force, and the firmer pads prevent deformation of the plastic during handling. Film materials, being thin and flexible, require vacuum pads that distribute the force evenly to prevent tearing or deformation. Pads with a larger contact area and softer materials are often used to gently handle films without causing damage. Foil, similar to film, is thin and can be easily deformed. Vacuum pads for foil handling are designed to apply minimal pressure while maintaining a secure grip. The pads often have a textured surface to increase friction without increasing the force applied. In all cases, the vacuum system's pressure and flow rate are adjusted to suit the material's characteristics, ensuring that the vacuum pad can maintain a secure grip without damaging the material. Additionally, the shape and size of the vacuum pad are selected based on the material's surface area and weight to optimize handling efficiency.
