Packaging machines need compact, repeatable pneumatic transfer for rotary sealing heads, indexing tables, vacuum stations, grippers, and filling mechanisms. Begapunk supports standard and custom air rotary unions for OEM packaging equipment.
Packaging machinery usually runs many cycles per shift, so the rotary joint must keep leakage low while tolerating repeated indexing, short dwell times, and compact installation space.
Common functions include pneumatic clamping, vacuum pickup, bag or pouch opening, rotary sealing, blow-off, and air cylinder actuation. Choosing the right passage count prevents control signals from interfering with one another.
Typical requirementCompact pneumatic rotary joint with low leakage, reliable sealing, and simple replacement.Confirm rotation style, indexing frequency, and whether the machine runs intermittently or 24/7.
Many packaging stations have limited envelope space, so body diameter, port direction, and hose routing should be checked early.
| Machine Area | Common Function | Selection Focus | Begapunk Direction |
|---|---|---|---|
| Rotary sealing head | Air cylinder and sealing pressure | Compact body, stable air path, easy maintenance | BP-2P or BP-3P family |
| Indexing table | Clamp, release, and blow-off | Multiple passages, flange mounting, anti-rotation support | 2P, 3P, 4P, custom |
| Vacuum packaging station | Vacuum and air release | Separate passages, good sealing, clean hose routing | Custom air/vacuum rotary union |
Send the machine function, passage count, pressure, RPM, and mounting drawing. Begapunk can help choose a standard model or quote a custom pneumatic rotary joint.
Yes, when passages are separated and the seal design is confirmed for the pressure and vacuum level.
Many machines can use standard 1P, 2P, or 3P models. Custom design is useful when space, port direction, or mounting pattern is fixed.
