Vacuum suction cups are usually made of rubber and metal skeleton structure. In the industry, designers will be divided according to the shape of suction cups: flat suction cups, oval suction cups, corrugated suction cups and shaped suction cups, in which corrugated suction cups are further subdivided into two-layer corrugated suction cups, three-layer corrugated suction cups and multi-layer corrugated suction cups. Commonly used vacuum suction cups material on the following four points.
- Nitrile rubber (NBR)
This material vacuum suction cup outstanding toughness, the use of temperature 120 ℃, good wear resistance, poor resistance to aging, oil, acid and alkali resistant water, vacuum suction cup manufacturers introduced this is currently the most widely used in the industry a vacuum suction cup material.
- polyurethane rubber (U)
Toughness is better, the application temperature is 60 ℃, good wear resistance, good aging resistance, good oil resistance, acid and alkali resistance and water resistance is poor. The above two are suitable for transferring hard-shell paper, plywood, and other usual workpieces. Vacuum suction cups made of polyurethane are very durable.
3.Fluorine rubber (FKM)
Toughness is not as good as the first two, but the application temperature can be as high as 250 ℃, except for poor alkali resistance other excellent features, can be used for transferring drugs.
- Silicone rubber (S)
The toughness is ideal, the application temperature is 200℃, the abrasion resistance is poor, the aging resistance is good, the oil resistance and acid and alkali resistance is poor, the water resistance is good. Suitable for transferring semiconductor components, thin workpieces, metal molding products, food products. The vacuum suction cup made of silicone rubber is very suitable for products with rough appearance.
