PET bottle blowing line: price, molds and capacity
The cost of a PET blowing section is made up of the blowing machine, molds, high-pressure compressor and cooling. We break down when a semi-automatic, linear machine, rotary blower or combiblock is the right choice.

What shapes the cost of a PET blowing section
| Budget item | What is included | What affects cost |
|---|---|---|
| Machine type | Semi-automatic, linear or rotary blower, combiblock | Required capacity and number of formats |
| Molds | Mold set for each bottle format, bases, necks | Number of SKUs and bottle geometry complexity |
| Air | High-pressure compressor, receivers, drying, recovery | Often up to a third of the blowing section budget |
| Cooling and energy | Chiller, piping, connected power | Capacity and shop temperature |
| Preform | Preform purchase or own injection | Annual volume and supplier availability |
Blowing is the only section where the calculation is built around bottle cost and break-even point, not around the filling line capacity.
How we calculate the economics of in-house blowing
- Step 1Break down bottle geometry
Volume, preform weight, neck, shape, stiffness and gas-barrier requirements. From here we get the number of cavities and machine class.
- Step 2Calculate break-even
We compare the price of purchased bottles with in-house cost: preform, electricity, air, amortization, labor. We show the annual volume from which blowing pays off.
- Step 3Select the compressor station
High-pressure air is half the operating cost of a blowing section. We calculate compressor capacity, recovery and drying.
- Step 4Decide on a combiblock
Separate blowing machine with air conveyor or blow-fill-cap combiblock. We compare by floor space, losses and cost.
- Step 5Calculate estimate and molds
Machine, mold set for each format, compressor and chiller, installation, commissioning and training. We separately budget for new molds.
Questions about PET blowing
From 12,000 bph up: a combiblock removes the air conveyor, saves floor space and reduces the risk of bottle contamination between blowing and filling.
Price depends on the number of cavities and geometry complexity. We list molds as a separate budget line so you see the cost of launching each new SKU.
This is the most common budget mistake. Blowing needs air at 25-40 bar, and the compressor station with drying is a significant cost. We always include it in the calculation.
