pet bottle blowing machine

Pet Bottle Blowing Machine Sourcing is an independent sourcing partner. Share preform drawing, bottle geometry, quantity and destination so we can request factory quotes for a pet bottle blowing machine. A catalog bottles-per-hour figure is not plant output until cavity count, mold, oven duty cycle and high-pressure air are stated with the same bottle.

Request Factory Quotes PET stretch-blow line with ovens, four-cavity mold and bottle discharge

Trial sequence

  1. Representative sample

    Send the preform drawing, neck finish, bottle volume in litres, neck diameter in millimetres and whether the package is cold-fill or heat-resistant. Two bottles with the same nominal volume can still need different tooling.

  2. Demonstration

    Ask the factory to run the quoted cavity count on that preform, with cycle time, oven zones and stretching rods recorded. A rotary heat-set brochure is not a four-cavity linear demonstration.

  3. Acceptance record

    Define wall distribution, dimensional checks and how rejects and startup preforms are counted. Throughput in BPH must sit next to those test conditions, not as a lone catalog speed.

Trial sequence

Procurement scope for a pet bottle blowing machine should name the stretch-blow path the buyer will own: preform infeed, heating, blowing, and bottle discharge. Modules left unnamed reappear as extras when the first accepted bottle is inspected. See why volume alone cannot size the machine.

  1. Representative sample

    Use buyer preforms where possible. Record resin, IV range if known, and the four-cavity bottle geometry that must share the same mold set. Public manufacturer tables list volume, neck and theoretical BPH as comparison fields, not as this service’s output promise.

  2. Demonstration

    Witness heating and blowing on the quoted mold, not on a substitute water bottle. Confirm whether air recovery, mold cooling and spare stretching rods are inside the demonstration package.

  3. Acceptance record

    FAT or SAT language should point to measured bottles from the trial, including changeover if more than one format is planned. The buyer signs the record; this website does not.

Utilities that travel with the quoted rate

Connections to confirm
InterfaceBuyer input
ElectricalVoltage, phase and frequency for ovens, hydraulics or servo axes, and connected load in kW for the quoted cavity count.
UtilitiesHigh-pressure compressed air demand at the quoted BPH, mold cooling water temperature and flow, and any low-pressure air for conveying.
ControlsPLC interface expected by the plant, interlocks to preform unscrambling and bottle air conveying, and whether a shared line recipe is required.

Questions before the first quote

Which procurement scope is covered by pet bottle blowing machine?

Defined specification

A defined RFQ names the stretch-blow frame, oven, mold set, cavity count and bottle discharge that must be quoted together. Four-cavity geometry, neck finish and fill temperature belong in that package so manufacturers answer the same bottle, not a substitute catalog SKU.

Send requirements

Selection still open

If automatic versus semi-automatic is still open, describe labor, hourly output and how many bottle families must share the same station. We will ask factories which route they will quote and which tooling stays optional.

Review sourcing steps
Which preform and bottle geometry applies to the four-cavity configuration?

Manufacturer four-cavity tables typically pair a volume in litres with a neck diameter in millimetres and a theoretical BPH. Ask the bidder to confirm which of those rows matches your drawing. Do not mix a rotary heat-set architecture with a four-cavity linear quote, and do not use an inconsistent heat-set table as a cavity proof.

Send the trial bottle, not only a catalog BPH
