Compare one-step and two-step bottle blowing routes by preform control, tooling scope, output target and sample acceptance.
Two-step routes separate preform and blowing decisions; one-step routes combine more process stages and need different tooling review.
Do not choose by process label alone; choose by bottle format, preform route and tooling scope.
| Factor | One-step route | Two-step route |
|---|---|---|
| Process | More combined process review. | Preform and final bottle blowing are separated. |
| Tooling | Injection and blowing assumptions are closer together. | Preform mold and bottle blow mold can be quoted separately. |
| RFQ data | Needs material, bottle and process target together. | Needs preform, blow mold, machine and output data. |
| Buyer action | Ask if combined tooling route is suitable. | Ask how preform, blow mold and machine fit together. |
