The thread unscrewing units (TUU) are used to demould threads in plastic and metal powder injection-moulded parts (MIM parts). They are mounted on or installed in the tool and ensure absolute repeatability.
Every TUU is assembled from individual standard modules for the specific use. For this purpose, the customer must communicate all requirements/conditions, such as drive type (hydraulic/electrical), axle distances (in the case of multiple TUUs), thread type, threaded region (drawings, dimensions, 3D model), thread direction (right/left), material of the injection-moulded part, space available (solution: angle TUU), etc., see request form.
Info: The most complicated constructions are feasible.
DESOI makes it possible.

SINGLE THREAD UNSCREWING UNITS
The single TUU is used to demould individual internal threads of any kind. The drive is hydraulic or electrical. The electric drive consists of a servo motor as well as an operating and control unit.
Double THREAD UNSCREWING UNITS
The distance between the axes of the threads is important. Different types of threads as well as thread cores of unequal length can be demoulded at the same time.
Fourfold thread unscrewing unit
In the standard version of the fourfold thread unscrewing unit, the threads must have the same axial orientation. The types and pitches of threads may be different, but must be unscrewed in the same direction of rotation – right or left. Special units for different directions of rotation are feasible.
Eightfold thread unscrewing unit
The modular design allows the realisation of all possible variants of a TUU. The models shown here are examples of standard units.
In principle, there is a solution for every deviating requirement.
Angle thread unscrewing unit
Limited space? No problem with angle TUUs. They perform the same tasks as the single-thread unscrewing units and are the solution to difficult spatial conditions.
Accessory – Flow Indicator
The visual control unit is installed in the cooling circuit of the core cooling system. If the impeller turns, everything's fine.
Accessory – Pressure protecto
The pressure protecto limits the output pressure to 3 bar in order to protect the sealing elements of the core cooling system.
The core cooling with integrated tempering tube is ideal for cooling thread cores, spindles, etc. Suitable tempering agents are water and oils.
Accessory – Temperature filter
The very fine filter prevents contamination of the coolant. The filter element is easy to exchange.
