Why Do Vacuum Suction Cups Swell, Harden or Crack? When an industrial vacuum suction cup becomes swollen, hard or cracked, replacing it with the same model may restore production temporarily. However, if the operating conditions remain unchanged, the problem can return. The first step is to identify what has changed in the cup and what it has been exposed to. […]
Vacuum Suction Cups for Hot Plastic Parts: Material Selection Guide Selecting vacuum suction cups for hot plastic parts requires more than checking a material’s maximum temperature. The cup must establish a seal, support the workpiece during movement and release it reliably. At the same time, the plastic component may still be warm, relatively flexible or sensitive to contact marks. For […]
NBR vs HNBR vs FKM Vacuum Suction Cups: How to Choose Choosing between NBR, HNBR and FKM vacuum suction cups starts with understanding what the suction cup actually encounters: the workpiece surface, contact temperature, oils or chemicals, handling motion and production cycle. NBR is a common choice for general industrial handling. HNBR can be considered when improved resistance to heat […]
Suction cup covers and non-marking suction cups address surface quality in different ways. A cover adds a separate contact layer over a suitable cup. A non-marking cup uses a material compound intended to reduce traces during direct contact. The right choice depends on the surface, the cause of the marks and the handling conditions. For an existing glass-handling line, the […]
