We could not release the 0.3 module injected plastic gears from the mold without destroying the gears. It seems that the gear teeth in the undercut area (quite large undercut) shrinked and the force needed to release the gear is too high.
Does anyone familiar with releasing difficulties of injection molding of plastic gears due to the shrinkage of the gear teeth in the undercut area of the gear? Any documented reference will be appreciated.
