- Minimum aging time
- : time to make internal & atmosphere
pressure same and molding possible.
- Maximum aging time
- : time to make residual blowing agent
content in expanded beads decreased and poor fusion
occur
- Optimum aging time
- : time to make internal & atmosphere
pressure same , molding good, residual blowing agent
content proper, cycle time in molding shorten and
fusion good.
- Aging time in 2nd expansion
- 2nd expansion in 2~4 hrs after 1st
expansion
(It is desirable to mold in 2~4 hrs after 2nd expansion)
