Unscrewing units

Units for unthreading threads in injection molding tools

The smooth, fast, and clean unspindling of molded parts requires powerful unscrewing units that can be compactly integrated into the tool. Depending on the application, our servo unscrewing units are grouped in different versions. A special feature of the Servomold unspindling systems lies in decoupling the threaded cores from radial forces from the drive train. Here, the interaction of pinion, thin-section bearing, lead screw, and spline profile ensures smooth, trouble-free operation with maximum efficiency.

  • Precision to 1/1000mm: Servo-electric control instead of hydraulic gambling
  • Space-saving and flexible: A drive for up to four threads
  • Completely ready for installation: Plug & Play instead of design effort

Servomold offers suitable solutions ranging from standard single screw units to space-saving units with worm gear, up to complex, high-cavity applications such as the 96-fold unscrewing. In order to ensure the perfect balance between easy integration and efficient power transmission, each gear assembly is designed as compact as possible.
