Polymers - Effects of fillers on weld line strength - Past event
Wed, Jun 30
|Polymer Tech – Design - Weld Lines
The location in an injection molded part where two flow fronts meet is commonly called a weld-line. It’s well known that weld-lines create weak areas in the molded part. Join us to understand weld line strength and the impact fillers and fibers have.

About the Event
Predicting the integrity of the weld-line becomes more complicated when fillers and reinforcing agents are added. The magnitude of this property reduction depends on the ability of the two melt fronts to knit together in a homogenous fashion during the molding process. There is a requirement that the designer can predict the amount of strength loss which can be expected prior to molding and testing the finished part. This training module will explore and discuss the effect of the plastic formulation, the moulding parameters, the part geometry, and the mould design itself and how they all combine to affect the final weld-line integrity.
