With thread unscrewing units internal threads in injection-moulded parts can be
demoulded easily, quickly, precisely, and economically. There is also the possibility
to combine several thread unscrewing units of different types and sizes. The optimal
solution is offered for each internal thread.
Features:
- high unscrewing speeds (max. 2,000 rpm)
- big torques
- hydraulic motors with 2.6 kW, 3.2 kW or 6.1 kW
- different unscrewing lengths available
- selection between 4 different centre distances
- different sizes of the thread unscrewing units:
- for internal threads with outside diameter 12mm, 18 mm, 35 mm, 78 mm
Advantages:
- robust, easy to handle and to maintain
- production of long threads without problems
- any start and end of thread radial adjustable
- suitable for right-hand and left-hand threads
- can be used with each conventional moulding machine with core puller
- positional exactness and reproducibility by mechanical stop
The thread unscrewing units are custom-made as for unscrewing length, thread pitch, right-/left-handed thread.
Only the corresponding thread core must be made by the mould maker. On demand, DESOI GmbH produces thread cores according to customers' drawings.
