Complete solution for the correct assembly of boxes to the harness where tightening operations are required. Including all the necessary checking for assure the correct sequence of the assembly process:

Ready for the future

EMDEP Tightening System is working around the world with more than one model of tightening controllers.


So, we can guarantee an easy transfer to other models according to customer needs.


We support next models of tightening devices:

    Positioning system

    Reaction time. Every movement is codified and transferred in a faster way improving the efficiency of the operations.


    Accuracy. EMDEP has created a special algorithm in order to improve the accuracy of the positioning system. Now, targets with short distance between themselves can be detected in a better way.

    Manufacturing modes

    Sequential test

    It is the predefined mode. All the wires and tightening operations are done in a sequential mode and in a predefined order.

    Random mode

    In this mode, the operator has different wires and selecting one and touching with the wire in a point, the system automatically identifies the wire and enables the appropriate sequence.

    Mixed mode

    Modes 1 and 2 can be combined.

    Multiple test options

    EMDEP Tightening System integrates all possible required test options in addition to the tightening operations. We can differentiate between the tightening and electrical test options:

    Test modes

    Electrical Check

    EMDEP Tightening System checks electrically all the wires involved in the tightening process:


    1. Verification of box presence and lock of it to avoid system cheats
    2. Continuity assurance of the wire before and after being tightened
    3. Continuity assurance of all the wires after finishing the process
    4. Detection of extra wires
    5. Detection of misallocated wires
    6. Detection of the presence of wires 
    7. Detection of wire shrink 

    Clear guidance to the operator

    1. On-board guidance

    1. LED for current wire pick-up box
    2. LED for current nut pick-up box
    3. LEDs for tool management
    4. LEDs for both ends of the wire (from and to)

    2. On-screen guidance:

    1. Clear guidance on operation to perform
    2. Clear instructions to solve errors
    3. Mirror of tightening controller screen
    4. Displaying of the current position of the spindle
    5. Displaying the status of the tool tray
    6. Displaying of complete information of the tightened and pending positions for current harness
    7. Overall of test details: harness id, box, reference and start time

    3. Smart tool management.

    The tool manipulation has been studied and the algorithm indicates the changes of the tool in the best moment to maximize the efficiency.  


    4. Multi-language interface.

    Easily translation to new languages. Unicode support: charsets such as Latin, Cyrillic, Hanzi, Kana, Hanja, Arabic, Hebrew, Greek, Armenian, Georgian…


    5. Auto-rescaling to the monitor resolution.

    Software detects the resolution and organize information presented in the monitor according to that.
