ABSTRACT:
Self-stripping thermoforming insert allows a newly formed article to be removed easily from the forming insert by compressing a region within the insert surface creating a void that allows the newly formed article to separate from the surface of the self-stripping insert. The portion of the insert that compresses is spring loaded and air driven. After the article has cooled the device is activated freeing the newly formed article for simple higher quality components from the thermoforming process.
