Generally speaking, using vacuum sucker to grab products is the cheapest way. There are various kinds of vacuum suction cups. The rubber suction cups can be operated under high temperature. The silicon rubber suction cups are very suitable for grasping the rough surface products. The polyurethane suction cups are very durable. In addition, in the actual production, if the sucker is required to have oil resistance, it can be considered to use polyurethane, nitrile rubber or vinyl containing polymers and other materials to manufacture the sucker. Generally, in order to avoid scratches on the surface of products, it is better to choose suction cups with bellows made of NBR or silicone rubber
when eoat uses vacuum suction cup (without clamp), it should be noted that the movement speed of the manipulator should not be too high, or a shear force will be generated on the suction cup, so that the product can easily fall down in the process of rapid torsion. In some cases, a clamp can be used to ensure the safe transportation of products. In view of the possibility of product adhesion to the mold, it is usually possible to install an air clamp to solve this problem. When the surface area of the product is too small or the product is too heavy to use a vacuum sucker, the same problem can be solved by using a clamp.
