Thread unscrewing units

The thread unscrewing units (TUU) are used to demould threads in plastic and metal powder injection-moulded parts (MIM parts). They are mounted to or installed in the tool and ensure an absolute repeatability.

Each of the 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/electric), centre distances (in the case of multiple TUU), thread types, threaded sections (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 designs are feasible.
DESOI makes it possible.

Double THREAD UNSCREWING UNITS

The centre distance of the threads is important. Different types of threads as well as thread cores of unequal lengths can be demoulded at the same time.

Fourfold thread unscrewing unit

For the standard version of the fourfold TUU the threads must show the same axial alignment. The types and thread pitches may be different but must be unscrewed in the same direction of rotation – right or left. Special units for different rotational directions are feasible.
