Question 1

What is a PET carbonated bottle blow molding machine?

Accepted Answer

A PET carbonated bottle blow molding machine (also called a PET CSD bottle blow molding machine or stretch blow molding machine for CSD) is a high-speed PET stretch blow molding machine specifically configured to produce carbonated soft drink bottles with petaloid bases. It stretches a PET preform axially and radially using a stretch rod and high-pressure air (3.0–3.5 MPa), forming a bottle that can withstand CO₂ internal pressure. Sailwin SW-F6H and SW-F8H-800 high-speed models produce up to 16,000 CSD bottles per hour.

Question 2

Why do CSD bottles need a petaloid base?

Accepted Answer

Standard flat-bottom or round-bottom PET bottles cannot withstand the internal CO₂ pressure of carbonated drinks (typically 3–5 bar). A petaloid base has 5 or 6 petal-shaped feet that distribute pressure evenly, preventing base blowout or deformation. Sailwin's PET carbonated bottle blow molding machines use precision petaloid base molds with tolerance ±0.02mm, compatible with PCO1881 and PCO28 standard neck sizes.

Question 3

What is the output of a PET carbonated bottle blow molding machine?

Accepted Answer

Sailwin PET carbonated bottle blow molding machines produce 12,000 BPH (SW-F6H, 6-cavity) or up to 16,000 BPH (SW-F8H-800, 8-cavity) for 330ml–600ml CSD bottles. The 14,257 pcs/H figure shown on our touchscreen capture is a live production record from an SW-F8H-800 running 330ml CSD bottles at 1.52 second cycle time.

Question 4

What bottle sizes can a PET CSD bottle blow molding machine produce?

Accepted Answer

Sailwin PET carbonated bottle blow molding machines produce CSD bottles from 250ml to 2L. The SW-F6H-800 (≤800ml) and SW-F8H-800 (≤800ml) are optimized for high-speed small-format CSD production. The SW-F6H-2000 handles bottles up to 1.8L for family-size carbonated drinks. Changing bottle size requires a mold change only.

Question 5

What is the blowing pressure for carbonated bottle production?

Accepted Answer

PET carbonated bottle production requires a high-pressure blowing system at 3.0–3.5 MPa — significantly higher than standard water bottle production (2.5 MPa). Sailwin's CSD-optimized machines feature a dedicated high-pressure blowing circuit that delivers consistent pressure for CO₂ pressure-resistant petaloid base bottles. Standard low-pressure (0.7–0.9 MPa) handles pre-blow and auxiliary functions.

Question 6

How do I get a quote for a PET carbonated bottle blow molding machine?

Accepted Answer

Please provide: (1) Bottle volume — e.g. 330ml, 600ml, 1.5L; (2) Required daily output; (3) Carbonation level — CO₂ volumes (e.g. 3.5 GV); (4) Neck standard — PCO1881 or PCO28; (5) Bottle shape — custom petaloid or standard. Sailwin will recommend the appropriate SW-F6H or SW-F8H model and issue a factory-direct quotation within 24 hours.
