Vacuum sucker, also known as vacuum spreader, is one of the vacuum equipment actuators. In general, the use of vacuum suction cup grabbing products is the cheapest method.Vacuum suckers are of various kinds. Rubber suckers can be operated at high temperature. Silicone suckers are very suitable for grasping products with rough surface.Suction cups made from polyurethane are durable. In addition, in the actual production, if the suction cup is required to be oil-resistant, it may be considered to use materials such as polyurethane, nitrile butadiene rubber, or polymers containing vinyl to make the suction cup.Generally, in order to avoid the surface of the product is scratched, the best choice is made of nitrile rubber or silicone rubber with bellow suction cup material is made of nitrile rubber, has a greater tearing force, so it is widely used in various vacuum suction equipment.
