Non-sealed vacuum chucks are designed based on the principle of negative pressure, typically composed of a cup body, spring, air holes, pressure switch, and other components. Unlike traditional suction cups that rely on common sealing elements to maintain vacuum, non-sealed vacuum suction cups employ advanced design and materials to establish effective sealing on the suction cup's surface, achieving the desired vacuum effect.

Compared to traditional suction cups, non-sealed vacuum suction cups offer the following advantages:

Elimination of the need to replace sealing elements, reducing usage costs and maintenance complexity.

Lower noise generation during use.

Non-sealed vacuum chucks find wide spread application in automated production lines and robotic systems for handling various items such as picking up workpieces, packaging materials, and metal sheets. Their efficiency, safety, and reliability make them an essential tool in modern industry.
