Material Selection
This section can be used to find out what wall thickness can
be used for certain plastic material along with helping chose a material to
use. When selecting a material that
you will be
using, it is important to look at:
Amorphous Vs. Semi-crystalline
Different fillers and reinforcing materials
Different effects of moisture on the
materials
How heat affects the viscosity of the
material
How mechanical properties are affected by
additives
Another
important issue with material is the parts wall thickness. This is the most important aspect of plastic
product design and can be determined by consulting MEG data, looking at similar
products and flow analysis. Material
selection is another important area to look at with the thickness of the
wall. Some important issues when sizing
of the nominal wall are thinner is better, constant thickness when possible and
thicker sections might require coring.
This
web site will look at many different aspects when deciding to choose a
material for your part. It will
help with some of these items when looking into material selection:
