What are the types and performance characteristics of vacuum suction cups
Types of vacuum cups:Common vacuum suckers include elliptical suckers, corrugated suckers, flat suckers and special suckers.

Performance characteristics of various types of suckers
1) The performance of the elliptical sucker: the best use of absorbable surface; Suitable for long convex workpiece; Stiffened vacuum sucker; Small size large suction; As versatile as flat and corrugated suckers; A variety of sucker materials; The embedded structure has high grasping power (disc type sucker). Typical application areas of elliptical suction cups: handling long and narrow workpieces with small grasping surfaces: such as pipe fittings, geometric workpieces, wood strips, window frames, cartons, tin foil/thermoplastic packaging products.

2) The characteristics of the corrugated sucker: 1.5 fold, 2.5 fold and 3.5 fold corrugated; Good adaptability to uneven surfaces; Grasp the workpiece to enhance the effect; Compensation for different heights; Gently grasp the fragile workpiece; Soft bottom ripple; The shank and upper part of the suction cup have high hardness. Flexible conical seal lip with strong adaptability; Bottom support; There are many kinds of sucker materials. Typical application areas of corrugated suction cups: handling dish-shaped uneven workpieces, such as: automotive metal sheets, cartons, plastic parts, aluminum foil/thermoplastic packaging products, electronic parts.

3) Flat sucker performance: high positioning accuracy; The compact design and small internal volume minimize grab time; Achieve high lateral force; On the flat workpiece surface, the wide sealing lip has the best sealing characteristics; When grasping the workpiece, it has good stability; The embedded structure of large diameter suction cups can achieve high suction force (e.g., disc structure suction cups); Bottom support; Large and effective suction cup diameter; There are many kinds of sucker materials. Typical application areas of variable frequency suction cups: handling flat or slightly rough surface flat or slightly dish-shaped workpieces, such as: metal plates, cardboard boxes, glass plates, plastic parts and wooden boards.

4) Special suction cups: as universal as ordinary suction cups; The particularity of the sucker material and shape makes it suitable for specific application areas/enterprises; Typical application area of special suction cups: handling workpieces with special properties. Such as fragile, porous, easily deformed surface structure.
