A combiblock joins blow moulding, filling and capping into one frame with one drive and one control system. The preform goes in at one end and the capped bottle comes out at the other, with no intermediate buffer and no bottle storage between blowing and filling.
A conventional line stores empty bottles between the blower and the filler, and that buffer is floor space, conveyor, and a place where bottles collect dust. A combiblock removes all three, and because the three machines share one control system, one operator can run the block. The saving is in the building, not in the machine price.
| Configuration | What is inside | Typical use |
|---|---|---|
| 3-in-1 monoblock | Rinse, fill, cap | Still water in bought bottles |
| Combiblock | Blow, fill, cap | PET lines with in-house blowing |
| Combiblock + labeller | Blow, fill, cap, label | Single-footprint PET line |
| Combiblock + packer | Blow to case | High-volume single-format plant |
The Blow-fill-cap Combibloc for CSD & Sparkling Water is the reference unit for this configuration.
Because there is no buffer, a stop at the blower reaches the filler in seconds. That is the trade: less floor space and less labour in exchange for less tolerance of short stops. The maintenance plan has to treat the blower and the filler as one unit, with one set of uptime targets.
Site requirements, air and water consumption sit with the Blow-fill-cap Combibloc for Still Water.
Consistent dimensions, a stable colour and a controlled moisture level. A preform that varies in neck dimension stops the filler; one that varies in temperature response changes the bottle. The block cannot compensate for an inconsistent input.
The same question is worked through from another angle in How to Choose the Right Load Cell Combibloc.
With change parts for the mould, the star wheels and the filling recipe, yes. The changeover is longer than on a filler alone because the mould set changes, and the production factor for a two-format week is lower than for a single format.
It is designed for one operator on the complete block, which is fewer people than three separate machines need. The saving is real only if the plant also removes the buffer and the bottle handling between stations.
The blower and the filler are mechanically linked, so bottles move directly from the mould to the filler. Removing the buffer saves space and dust exposure, but it also removes the cushion that absorbs short stops.
It needs high-pressure air for blowing, which is usually a dedicated circuit. Sharing a low-pressure line with the rest of the plant is the most common cause of unstable bottle quality.
