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.
