Cumsa USA offers new lifters from the Smart Worm family for the release of small undercuts. The company says that this new component is ideal for releasing small undercuts and that it comes in two versions. Cumsa offers the Smart Worm Pin (WP) or the simple version, which is capable of fitting small clips with short ejection strokes (ranging to 30 or 60 mm). Cumsa also offers the Smart Worm Lifter (WL), which is a long version to help simplify the release of small undercuts for large molds that require more ejection strokes (ranging to 125 mm). The WL is compatible with Cumsa DR lifters.

Cumsa offers both Smart Worms in different sizes—the WP in Ø6 and Ø8 mm and the WL in Ø8 and Ø12 mm. Cumsa says that the advantage of the Smart Worms is that they do not need any mechanism in the ejector plates. Their bendable core (ranging to six degrees) makes it possible to release the undercuts simply by pushing up from the ejector plates.
