Failure Mode Effect Analysis (FMEA) Support
By leveraging mold filling simulation,
multiphysics simulation, and the understanding
of the link between design, process and material,
we can help inform your decision-making
process for product development.
Values reported as “typical” or stated without a range do not state minimum or maximum properties; consult your
sales representative for property ranges and min/max specifications.
Processing conditions can cause material properties to shift from the values stated in the information.

Material Selection
The most common word used to describe a soft touch overmold is “feel” — but the term
itself is very difficult to describe.
When a designer wants the product to feel “grippy” or
“squishy”, what exactly does this mean in terms of material properties?

The composite parts held
up well, and passed stringent standards for long-term
performance.

Switching materials from a metal to a polymer carries
large and potentially costly risks in terms of both
performance and production, so Avient Design was
consulted to help alleviate these concerns.

Ready for testing, the new material was subjected to
rigorous environmental testing, including months of
sun exposure and long-term placement in humidity-rich
environments.
