Understanding PET Packaging Manufacturing Technologies
PET packaging manufacturers use different moulding technologies depending on product
requirements, production volumes, and packaging complexity. Two commonly used solutions
are Single Stage Moulds and Blow Moulds.
Understanding the differences between these systems helps manufacturers select the right
production approach for their application.
Leo Precision provides both Single Stage Mould solutions and Blow Moulds for diverse PET
packaging requirements.
What Are Single Stage Moulds?
Single Stage moulding integrates preform manufacturing and bottle blowing into a single
production process.
In this system:
- PET resin is injected into a preform mould.
- The preform remains within the production cycle.
- Stretch blow moulding forms the final bottle.
This process eliminates the need for separate preform handling and transportation.
What Are Blow Moulds?
Blow moulds are used in a two-stage manufacturing process.
In this method:
- Preforms are manufactured separately.
- Preforms are stored or transported.
- Blow moulding machines convert preforms into bottles.
This approach is commonly used for large-scale bottle production.
