Which material for forcibly unmolded thrads
(OP)
Hello,
does anybody can give me some instructions of forcibly unmolding of the thread. Not to unscrew the thread but to pull it out from the part.
Which grade of PP or PE-HD to use?
... more instructions?
Thanks, Thomas

It's hard to make a call without seeing the geometry of the part. PP and PE are good materials for 'bumping off' threads but a lot of the mechanics in doing it is down to the design of the mold. When you have the design right obviously you can play around with variables like cycle time and temperature.
