The difference between sponge suction cup and vacuum suction cup

- Sep 05, 2019-

Vacuum suction cups, also known as vacuum spreaders, are one of the vacuum actuators. In general, the use of vacuum chucks to grab articles is one of the cheapest methods. Vacuum chucks are available in a variety of sizes. The suction cups made of rubber can be operated at high temperatures. Suction cups made of silicone rubber are ideal for gripping rough surfaces; suction cups made of polyurethane are durable.


In actual production, if the suction cup is required to have oil resistance, it is conceivable to use a material such as polyurethane, nitrile rubber or vinyl-containing polymer to manufacture the suction cup. Generally, in order to avoid scratching the surface of the product, it is preferable to select a suction cup with a bellows made of nitrile rubber or silicone rubber, which is made of nitrile rubber and has a large breaking force, so it is widely used. Various vacuum holding devices.




Sponge suction cups are widely used in vacuum gripping applications, such as robot palletizing, demolition; material handling; marble, ceramic tile, ceramic products, building materials, packaging bags, stone, wood, carton, metal sheet... almost large Most areas where vacuum gripping can be applied can be grabbed in this way.


For example, carton, wood is a little breathable or the surface is not very flat adsorption, the adsorption surface is more large, that is, the suction is much larger than the ordinary suction cup. Due to the small adsorption area of the vacuum chuck, the adsorption of some products has a certain one-sidedness for the vacuum chuck. Vacuum chucks are generally used for surface flattening without bumps or holes.
