Servo-electric unscrewing unit
The servo-electric unscrewing unit (SLU) combines the unscrewing motion with a synchronized, linear slider movement. It demolds helical internal and external contours with micrometer precision and repeatability. The standardized core holder accommodates individual mold contour attachments, allowing for a quick change between different contours and pitches.
Advantages at a glance
Electronically synchronized master-slave control - backlash-free, high-precision rotary and linear motion in one unit
Large thread pitches easily achievable – overcomes the limits of classic lead screw nut systems
Fully integrated slide and core cooling – optimal cooling performance for shortest cycle times
Cleanroom suitable – without hydraulic oil, free of leaks, minimum quantity lubrication
No wear on the guide bush, no susceptibility to contamination - higher availability, lower maintenance costs
Universal core holder in preloaded tapered roller bearings – locked μm-precisely against injection pressure
Standardized core holder with individual contour inserts - quickly exchangeable, maximum flexibility
