Product Features
PFG/PF series heavy-duty industrial vacuum suction cups are large-size high-load pneumatic gripping accessories available in 120mm, 150mm, 200mm and 250mm specifications, equipped with two standard A18 and A22 thread interfaces to adapt to different mechanical arm fixtures. Adopting thickened industrial-grade silicone rubber through integral molding process, the suction cup features ultra-high elasticity, solid structure and durable overall toughness. Different from ordinary small suction cups, this heavy-duty model is specially optimized for large and heavy workpieces, with widened and thickened suction edge design. It can closely fit rough, uneven and slightly curved surfaces of stone, glass, wood and other panel materials, forming a high-tightness vacuum sealing environment. With strong load-bearing capacity and stable vacuum adsorption performance, it supports long-term high-frequency heavy-load grabbing operations. Standard thread mounting structure ensures high compatibility with large industrial manipulators and automated processing equipment for stone, glass and woodworking industries.
Product Advantages
This heavy-duty silicone rubber vacuum suction cup has unique core advantages for large workpiece automated handling scenarios. Firstly, super strong heavy-load adsorption capacity. The large-diameter oversized suction surface provides extremely high vacuum pulling force, stably gripping heavy stone slabs, glass panels and wooden boards without slipping or falling off, meeting high-load industrial handling demands. Secondly,excellent adaptive fitting performance. The soft thickened silicone edge can perfectly fit rough, unpolished and uneven workpiece surfaces, effectively solving the air leakage problem of ordinary suction cups on non-smooth materials and maintaining lasting and stable suction force. Thirdly, industrial-grade durable material. Premium thickened silicone rubber features outstanding wear resistance, aging resistance and tear resistance, resisting long-term friction, extrusion and high-frequency use in harsh processing environments, with a longer service life than ordinary suction cups. Fourthly, high versatility and easy matching. Multiple sizes and two universal thread interfaces support flexible matching with various large manipulator equipment, realizing one-stop selection for different heavy-load grabbing scenarios. Fifthly, wide industrial applicability. It is perfectly suitable for automated loading, unloading and handling of stone processing, glass deep processing, woodworking manufacturing and large plate material production lines, with high cost performance and stable industrial practicability.
How to Use
First, inspect the suction cup before installation to check for cracks, deformation, aging, surface damage or air leakage, and select the corresponding size and A18/A22 thread interface according to the manipulator fixture and workpiece weight. Second, clean the thread mounting position of the mechanical arm and the suction contact surface of the workpiece, remove dust, debris, stone powder and oil stains to ensure clean and dry fitting surfaces for better vacuum tightness. Third, align the suction cup thread with the fixture interface, screw it tightly and fix it firmly to ensure no looseness at the connection and avoid air leakage during operation. Fourth, connect the pneumatic vacuum system, turn on the air source for air tightness test, check the connection and suction edge for air leakage, and adjust the vacuum pressure to the reasonable working range according to the workpiece load. Fifth, conduct trial grabbing for target heavy workpieces such as stone, glass and wood panels, fine-tune the vacuum pressure and manipulator lifting speed to ensure stable and firm grabbing without workpiece shaking or falling. Sixth, after confirming the trial operation is normal, start formal automated loading, unloading and handling work. For daily maintenance, regularly clean dust and residual debris on the suction cup surface, check the silicone edge for wear and aging, and replace the suction cup in time if suction weakens or sealing fails, to ensure stable and safe operation of heavy-load automation equipment.
