Vacuum cups are very useful devices that are used in many automated handling systems. From lifting and moving cola cans to car parts, several industries consider Convum vacuum cups as the best devices. Vacuum cups are available in different types, sizes, construction styles, and there are other factors to differentiate between their types. So, if you're planning to buy vacuum cups, you must consider the following factors.
Construction
Vacuum cups are developed in a number of ways with regards to the shape they take, the materials they're made up of and the details they have along their exterior as well as their interior. These cups include ribs on either their exteriors or interiors for added support, as may be needed to hold a product in place.
Shape
When it comes to shape, vacuum cups are available in two shapes - flat and bellows. The flat ones are used to handling workpieces but only the ones that are flat or have curved surfaces. Flat vacuum cups are used to pick plates made of glass or metal, plastic sheets, and other flat items. They are well-designed vacuum cups and are used by many industries out there. They are very rigid and stable so that they can handle high shear forces and fast automated-handling movements. On the other hand, bellows vacuum or suction cups are adept at handling parts that have uneven surfaces. Convum vacuum cups with the bellow version are used to lift fragile parts of machinery. They include car body panels, pipes, tubes, shrink-wrapped products, and more.
Interior volume
You must check the interior volume as it judges the level of vacuum and the holding force of the cup. Flat vacuum cups have small inner volume and they are not great when it comes to holding a grip for a long time. A cup volume calculation is not quite difficult. First, you need to measure how much air is going to fit into your mixture. Then, multiply the measurement by the number of cups you are going to use. Once you know that amount, it's time to calculate how long it will take for all of the air bubbles to get out.
Environment
While buying vacuum cups, you also have to consider the operating and workpiece temperatures. It depends on the application and the settings of the machinery and you have to think about if the vacuum cups have to go through rough or porous surfaces or washdown solvents. For example, the ones made of silicone can go through –30 to 180° C and fluoroelastomers to nearly 200° C.
