Drying
Drying is recommended.
Points to watch
- Degradation with moisture and at high temperature
- Visibility of weld lines
Defects common with this material
Splay (silver streaks)
Fine silvery streaks on the part surface in the flow direction.
Brittleness / low impact strength
The part breaks more easily than expected; sometimes the surface looks fine.
Stress cracking
The part cracks during assembly, on contact with oil/solvent or over time; the crack usually starts at stressed areas.
Weld line (knit line)
A line and a weak zone where two melt fronts meet.
Short shot (incomplete fill)
The cavity does not fill completely; the farthest or thinnest area of the part stays incomplete.
Flash
Plastic escapes through the parting line or around the ejector pins.
