Short answer for automatic machine buyers.
An automatic PET bottle blowing machine should be selected from bottle size, target output, cavity plan and downstream handoff, not from automation label alone.
- Start with 4 constraints: bottle geometry, preform route, output target and mold fit.
- Compare automatic routes only after deciding machine-only or machine-plus-mold scope.
- Downstream conveyor, take-down and filling interface can change the final route.
