Servo-electric linear unscrewing unit (SLU) This Servomold unit is designed for demolding helical internal contours, such as the threads found in auto-injector pens and similar drug-delivery systems. The unit moves the core both rotationally and linearly with micrometer-level synchronized precision. One servo drive generates the rotational movement, and a second generates the linear stroke, while Servomold's MoldControl system synchronizes both axes electronically. Rotational and linear movements can also be used independently. The SLU comes in two sizes, with minimum core spacings of 40mm and 60mm, and a single unit can drive up to eight threaded cores. The integrated linear guide simultaneously guides the slide body and enables demolding of additional, non-rotating contours. Cooling of the slider and core is integrated directly into the system, enabling short cycle times.
What's new? The SLU, which debuted at Fakuma and is available in the U.S. through DME.
Benefits Fast, accurate demolding of threaded parts. No hydraulic oil is used, allowing use in cleanrooms.
