- Unscrewing units for gentle demolding of threaded parts
- Precision movements in the most confined spaces
- Showcase at #EuroMold 2014
Servomold is the collective designation for a number of servo-electric systems developed by company i-mold for the precise and space-saving realization of complex movements in injection molds. High precision movements combined with gentle acceleration and deceleration of high-speed movements enable short cycle times.
0.01 mm – the exact positioning of the threaded core
While single-cavity and four-cavity unscrewing units for the demolding of threaded parts now count among typical applications, the company also supplies units for multi-cavity molds with up to 72 closely packed cavities. Also new is a series of very compact servo-screw unscrewing units for the gentle demolding of threaded parts featuring exact positioning of the threaded core (<0.01 mm). Available as single, double and four cavity units, they can be bolted to the mold in any desired position, also on the stationary half of the mold. The motor, to which they are coupled, can be mounted on the outside of the mold. Typical applications include the unscrewing of threaded parts, the actuation of splits when demolding parts with undercuts and the use in clean room applications.
At the upcoming #EuroMold 2014 exhibition the company will also showcase its range of tunnel gate inserts which are suitable for all unreinforced and for most reinforced polymers. Possible shot weights range from less than 1 g to over 1,000 g (depending on the type of insert and the melt viscosity). The recently introduced TG types, for instance, feature a tightly curved runner and are hence particularly space-saving. They may also be used for sub-gating behind an all-around rim or for internal gating above the parting line.
