About the part design:
Molded-in stress in parts can be minimized by:
1, Avoiding thin walls and sharp corners
2, Avoiding large and sharp transitions in wall thickness
3, Ensuring balanced and uniform part filling
4, Properly designing ribs and corning to increase stiffness without increasing wall thickness
Injection molding Process:
Drying Parameters
Moisture content higher than 0.02% can be
expected to cause appearance issues, brittle parts and an increase in the melt
flow of the material. If it is unreinforced material, then you have to dry 4
hours at the temp of 300F ;
if it reinforced material, then you have to dry 6 hours at the temp of 300F , if it is blended material, then you
have to dry 6 hours at the temp of 275.
Melt Temperature
The melt temperatures ranging from 640 to 750F are common. A melt temperature of 675 to
725°F is typical for most
applications. Temperatures over 720°F
may result in a color shift due to the inability of pigments in some colors to
handle higher temperatures.
