A rubber suction cup is a device that uses the principle of negative pressure to achieve fixation, suspension or sealing. It is usually made of elastic rubber materials (such as natural rubber, silicone, nitrile rubber, etc.). Its working principle is to press out the air inside the suction cup to create a vacuum negative pressure, thereby adhering to smooth and flat surfaces.
The main types of rubber suction cups
Ordinary flat-bottom suction cup: Suitable for smooth surfaces, such as glass, tiles, metal, etc.
Wave-shaped suction cup: With a pleated design, it can adapt to slightly uneven surfaces.
Deep-type suction cup: Used for adhering to curved surfaces or in scenarios requiring stronger adhesion force.
Hook/Handle suction cup: Convenient for hanging items, such as bathroom hooks, kitchen utensils, etc.
Industrial suction cups: Used for moving objects by robotic arms and automated equipment.
Advantages of rubber suction cups
No need for drilling or gluing
It does not damage the wall or surface, and is suitable for temporary or movable fixed installations, such as for renting or home decoration.
Easy to install and reusable
Press down to attach, and when disassembling, simply lift the edges easily. It can be adjusted to different positions multiple times.
Adapt to various smooth surfaces
It is suitable for non-slippery surfaces such as glass, ceramics, metals and plastics. Some corrugated suction cups can also adapt to slightly uneven surfaces.
Low cost and highly practical.
Compared with drilled installation or magnetic fixation, rubber suction cups are cheaper and easier to replace.
Silent and shockproof
The rubber material can absorb vibrations and is suitable for securing fragile items or reducing noise during equipment operation.
Waterproof and moisture-proof
Silicone or synthetic rubber suction cups have excellent water resistance and are suitable for use in damp environments such as bathrooms and kitchens.
Lightweight load-bearing
The load-bearing capacity of high-quality suction cups can reach several kilograms (for example, vacuum suction cup hooks can hold heavy objects), and industrial-grade suction cups can even lift large objects.
