Understanding Suction Cups – their types, characteristics & uses

A suction cup is a device that can make use of the difference between the atmospheric pressure inside and outside and the adsorbed material or a tool that can capture the subject. You can use glass suction cups when you have something to pick up on your bottle. You might use bottled suction cups if you have a glass or something with a smooth, non-porous surface. Typically they are round, but some of them are rectangular. They are constructed of airtight materials, most notably.

As the middle of the vacuum, the cup is pressed against a flat non-porous surface, the size of the area between the vacuum cup and the flat surface decreases, which contributes to the air between the cups and surrounds being ejected through the circular cup rim. The vacuum cup is made of flexible, elastic material and a curved surface.

The air tightness between the cups of rubber and silicone are exceptional. There is a concave region at the base of the caps. Since the ambient pressure still attempts to maintain its equilibrium, this pressure moves outdoor air. Because the sucker’s surface cannot be breached, it forces the sucker to hold it firmly to the surface. If the surface or boundary of the suction coupling is broken and the outside air enters the suction cup, it does not work correctly and will drop off. The air tightness should be checked before the suction cups are applied. The weight of the adsorbed products should also be verified if it exceeds adsorbed power. If the suction cup comes down, it will have serious consequences.

Types & Characteristics of Suction Cups

Suction cups can be made out of various materials –

Natural Rubber

Natural rubber suction cups have a high resistor and a tear resistance, reliable and not easy to break.

NBR

NBR content is the best for oil touch suction cups. NBR has very little pressure resistance and antistatic properties and is a semiconductor rubber material.

HNBR

HNBR is a higher-saturated, nitrile butadiene rubber elastomer with high-temperature strength, cold strength, excellent mechanical efficiency, high strength, strong tear-resistance, excellent abrasion-resistance, etc.

Silicon

Silicone suction cups are colored, healthy, and environmentally friendly. They are very resistant to aging, have no animal refuse reaction and are well-bodied, and are uniquely suited to medical products.

Polyurethane

Polyurethane is more versatile, more durable, more mechanical, and oxidation-resistant than other rubber. Polyurethane is very commonly used in gasoline, water, and fire resistance.

VITON

The high chemical stability of the VITON suction cup is the best material for a heavy acidic and alkaline environment with outstanding tolerance to temperatures. It can also operate at 300 ° C for a long time.

Some applications are as follows

  1. Using suction cup hooks to hang items onto the glass or tile surfaces in a bathroom or kitchen.
  2. The manipulator uses small suction cups to catch objects in industrial manufacturing.
  3. Using strong suction cups to climb high-rise glass walls.
  4. A two-sided suction cup can be placed between two separate pieces of glass, and cups can be supported and sealed.
