Process Parameters:Single-Stage Injection Stretch Blow MoldingThis 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 Who should
attend? Operators, processors, plant engineers that are new to single-stage molding, or who want to refresh their knowledge and gain new insights. This is a beginner’s course: an advanced course will be offered shortly.
