A vacuum suction cup is a device designed to create a strong and airtight seal against a surface using negative pressure or suction. It is commonly used in various applications where holding, lifting, or attaching objects to smooth surfaces is required. When the vacuum source is activated, the air is removed from the cup through the vacuum port, creating a partial vacuum or negative pressure inside the cup. This pressure difference between the inside and outside of the cup generates a strong holding force, allowing the suction cup to grip onto the surface. A release valve that allows the user to quickly release the suction and detach the cup from the surface. Vacuum suction cups find applications in various industries, including material handling, glass installation, robotics, packaging, and many others. They provide a versatile and reliable method for temporarily securing objects to smooth surfaces without the need for permanent fixtures or adhesives.
