Single Stage Molding Parameters
This course is a practical introduction to the technology of single-stage PET stretch blow molding. It gives participants in-depth instructions on how to set up and run the machine for optimal bottle quality.
Topics include:
- To make a good bottle we need a good preform: the need to start right
- Injection speeds, pressures, switch-over point
- Hot runner manifolds: design and control
- Update: Viscous heating, explanation and solutions
- How to control the cushion and what it means to the process
- Fast or slow injection and how it changes the blowing parameters
- The conditioning station: control of optimal wall distribution
- Stretch rods: Tip designs, adjustments
- First and second blow pressure: the secret of timing and how it relates to bottle wall thickness
- Common molding problems and their solutions
