A PET water bottle blowing machine uses biaxial stretch-blow molding to produce hollow PET bottles from preforms. The preform is heated in an infrared tunnel, then a servo stretch rod extends axially while 2.5 MPa air inflates radially into the mold shape.

Sailwin water bottle blowing machines produce 3,000–18,000 BPH in 2 to 9 cavity configurations.

2-cavity entry-level: ~3,000 BPH. 6-cavity standard: 9,000–12,000 BPH. 9-cavity high-speed: up to 18,000 BPH. Actual output depends on cavity count, bottle volume and cycle time.

Yes. Sailwin machines produce thin-wall bottles down to 6g for 330ml. PID infrared heating + servo stretch ensures uniform biaxial orientation — the key to thin-wall integrity. Reduces PET resin cost 15–20% per bottle.

Yes. Sailwin supplies turnkey blow-fill-cap inline lines: preform loader → blow molder → conveyor → filler → capper. Eliminates bottle storage, reduces contamination risk and labor cost.

100ml to 2L. Round, square, hexagonal, slim, grip waist or custom OEM shape. Changing bottle size = mold change only, no machine replacement needed.

Yes. Sailwin's mold team designs and manufactures custom molds for any bottle shape. Provide a sketch or reference sample — mold cost and timeline quoted within 3 business days.

Please provide: (1) Bottle volume; (2) Bottle shape; (3) Required daily output; (4) Whether filling line is needed; (5) Power supply. Sailwin recommends the right cavity configuration and replies within 24 hours.
