Bellows vacuum cups for short-cycle automated plastics applications

fp041-varioflex-vacuum-cups-for-plastics-prFIPA Inc., a manufacturer of vacuum technology, gripper systems, air nippers, tube lifters, and end-of-arm-tooling has announced its SP-BX Series Varioflex bellows vacuum cups for short-cycle automation applications in the plastics industry.

Varioflex bellows vacuum cups are made of an oil-, ozone-, and wear-resistant polyurethane composite material that can withstand temperatures up to 50°C (122°F) and regular contact with abrasive surfaces over extended periods of time. Featuring a dimensionally stable body (60° Shore A, black), a soft, low-marking sealing lip (30° Shore A, red), and bellows with 1.5 or 2.5 folds, SP-BX Series vacuum cups facilitate the gentle and reliable lifting, handling, and placement of hot, delicate, curved, and even rough plastic parts while effortlessly compensating for small to medium height and angle differences between workpieces to effectively minimize suction loss due to micro-leakage. The combination of the series’ stable body and soft sealing lip also achieves high holding force and high stability against lateral bending, even under unfavorable manufacturing conditions, which significantly increases reliability in short-cycle applications like removing hot parts from injection molding machines.

Rated for use in temperatures ranging from 10 – 50°C (50°F – 122°F), FIPA’s Varioflex bellows vacuum cups are offered in two sub-series. SP-BX1 Series Varioflex bellows vacuum cups are available with diameters spanning 16 – 160mm, and have bellows with 1.5 folds to compensate for material height differences and stabilizing cleats to enable fast acceleration and prevent the deep drawing of thin materials like sheet metal. SP-BX2 Series Varioflex bellows vacuum cups are available with diameters spanning 16 – 77mm, and have bellows with 2.5 folds to accommodate applications that require both height and angle compensation, like demolding injection-molded parts. SP-BX2 cups with diameters of at least 77mm also feature a filter disk between the bellows, and optional filter disks are available for SP-BX2 cups spanning 26 – 53mm in diameter.
