Bellows Suction Cups, as one kinds of Industrial Suction Cups & Pads for lifting or mounting, known as Rubber Vacuum Cups & Feets which are made from elastomer materials or clear silicone materials by rubber compression molding or injection molding,
Bellows Suction Cups can suck and lift different materials, such as stainless steel, copper, iron, insulation board, glass, ground brick, concrete casting, steel plate, cylinder without damaging the objects’ surface. So vacuum suction cups are widely used for moving and fixed objects.
Rubber Suction Cups & Vacuum Pads Working Principle
Connecting the elastomic rubber suction cups with the vacuum equipment via a elastomeric silicone rubber, plastic or metal tube, then attaching with the targeted-lifted objects like glass, panel, board or paper and trigger the vacuum equipment to suck or hook, which will produce negative pressure in silicone rubber vacuum cup and then it will start moving the targeted-lifted objects. When it has moved the targeted-lifted objects to the target place, vacuum suction equipment will smoothly inflated into the elastic rubber suction cup to change the negative pressure in elastic vacuum cup into zero pressure or a bit of positive pressure, then the silicone rubber vacuum cup will separate from the waited-lifted objects, then the moving objects task finished. Vacuum Suctions is widely used inindustrial suction cups equitment& mechanical arm, and also in our daily life.
Rubber Suction Cups Main Materials
Bellows Suction cups come in a wide range of materials to meet specific application requirements. Common materials include nitrile, silicone, and natural rubbers, fluoroelastomers, and polyurethanes. Some materials, for example, are particularly suited for smooth, rough, or oily surfaces, or easily damaged workpieces.
Major Defects of Bellows Suction Cups in the market
Splitting & Bubbles Problem: This problem is mainly caused by Molding temperature & poor venting. If molding temperature is too high, air-venting is not good, and flashing of last mold doesn't clear thoroughly, splitting and bubbles problem will show up.
White Faded Marks problem was caused by silicone hose's material & mold tool's surface.
Uneven Wall Thickness: this problem mainly caused by mold tool, like mold-making precision, misalignment of upper mold and down mold, datum angle & the 4 located pins are not accurate enough.
Rubber Flashing is too big: to solve this problem, we need to pay attention to 3 points when production; the first one is mold-design, second one is workers' skill about removing flash, and the production technology is also very important, if molding pressure is not enough, will also make the flash hard to be removed.
Silicone Bellows Suction Cups Advanatage:
Easy to use: No matter what is sucked object material, as long as it can seal, air-proof, all can working. Electromagnetic chunk & suckers only working with metal matierals.
Not hurt to object components: Because Vacuum suctions cup is made from elastomer rubber materials, objects will not damange when sucking or lay down3. Environment friendly:Silicone Rubber Industial Suction Cups will not pollute the environment when working, also will not create light, heat or electromagnetism etc.
