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 |
Sizing for this duty runs through the Still Water 5L Volumetric, where the valve count is set out.
With a positive-pressure enclosure over the blow-fill-cap path, filtered air, and a defined cleaning cycle for the filler and the capper. The bottle is formed, filled and closed inside the same zone, which is the reason the format exists.
The specification sheet for the Blow-fill-cap Combibloc for Still Water carries the utility figures quoted here.
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 Blow-Fill-Cap Machines Improve Bottled Water Safety.
A monoblock combines rinsing, filling and capping. A combiblock adds blow moulding, so the preform goes in and the capped bottle comes out. The two terms are often confused, and the difference is whether a blow moulder is inside the block.
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 filler stops within seconds because there is no accumulation. That is why the uptime target for a combiblock is set for the block, not for each machine, and why preventive maintenance on the blower is not optional.
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.
