Short answer for PET preform mold buyers.
A PET preform mold quote should connect preform weight, neck finish, material, cavity target, injection route and final bottle blow mold fit.
- Preform mold controls preform weight, neck finish and upstream consistency.
- Final bottle performance still depends on how the preform works with the blow mold and machine.
- Quote preform mold separately from blow mold unless both tooling scopes are required.
