INJECTION MOLDING MACHINE INFORMATION

           Screw retraction before dosing (%)                * The speed of screw retraction before refill can be set here.   Screw retraction after dosing (%)              If   * This speed setting determines the speed of screw retraction after refill (suck back speed).           Screw retraction after dosing (mm)              * The end position of the screw after retraction is set here.  Dosing stop (mm)                   * The end position of the screw after dosing. This determines the shot weight of the screw after dosing. Dosing volume is a function of stroke in mm.         Screw retraction before dosing (mm)                *The end positio...

This page comprises of the most important process parameter. Cycle time Set  The set cycle time acts as a monitoring time for the completion of cycle. If, due to some reason, the cycle fails to complete within the set time, the machine will signal an alarm.  Actual: The time taken by the machine to complete one cycle. The set cycle time should be higher than the actual cycle time.          Cycle time - last shot                     #   The time taken by the machine to complete the previous shot. Useful for checking the effect of a change in the process parameter.         Blocking time                 #  Blocking time starts after the set cycle time expires. At the end of blocking time the machine goes into shut-off mode as per the switch off matrix setting.         Pa...

 Press Ejector hot key  Or Enter page number   Or Select page in page index menu  * Hydraulic ejector forward is controlled with single stage pressure and two speeds.  * Retract controls are with single pressure and single speed Ejector Forward (as per the above settings)   Hydraulic ejector is triggered when machine is at mould open-stop position.   At this position, the delay timer of 0.00 sec triggers the ejector at 160 bar pressure and a forward speed of 50%.    On reaching the trigger point 50 mm, the speed is changed to 50%.   Ejector forward movement is stopped at 160 mm.  At the forward end if multi stroking is not selected the stay forward time is actuated for the set time of 0 seconds  Ejector Retract (as per the above settings)      The ejector retracts at 25 bar pressure with 15% speed.   The same sequence is repeated once again as the ...

To select this page    Press Mould setup hot key         For mould open, 3 speeds can be set with corresponding stroke values.     For mould close, 3 speeds can be set with corresponding stroke values.     The pressure for mould closing can be set from zero to 160 bar   1. Mould moves from the fully closed position with slow speed of V1=10%  2. On reaching 25 mm, the speed increases to V2=35%   3. On reaching 180 mm, the speed decrease to V2=12%   4. Mould comes to a stop at 230mm  1. Mould closes from the fully opened position with slow speed of V1=10%   2. On reaching 200 mm, the speed increases to V2=30%   3. On reaching 60 mm, the speed decreases to V2=6%  4. The mould sensing starts at  40 mm, closing pressure limited to 5 bar  5. Mould sensing ends at 2.5 mm and the mould locks   6. The mould closing pressure is 75 bar up ...

The various functions of the machine are grouped together and each group is assigned an IBED page.    The IBED pages can be accessed in three ways:     By pressing the respective function keys the page can be directly accessed. However the access is limited to 10 most frequently used pages.     By clicking the ‘i’ button in the screen, an index of pages is displayed. The required page can be easily accessed by scrolling the slider in the window and double click on it to open.   The required page can also be accessed by clicking the page number button and enter the page number in the numeric window    To select this index menu   Press  i button  on top group of the screen     This page shows an index of all the installed pages in the LNC6 system with a text description of the pages.     Any page can be accessed by double click on respective page number.    Each page consist...

LNC6 PLC INJECTION MOLDING MACHIN E The efficiency of the machine is based on the use of microprocessor control. In order to operate these control systems reliably it is necessary to keep them free of all interference. We have suppressed possible sources of interference. However, with regard to sources of interference outside the machine, suitable measures must be taken by the users. The user interface, also popularly called as IBED (pronounced ‘eye bed’) by TMIC users, is an important device for operating the machine. Here In This Blog You are going to learn about function keys and some special keys About injection molding plc.  MAIN FUNCTION KEYS *The ‘ABC…’ key switches the Manual and ‘F’ keys into ASCII characters including letters.  This key should be activated while entering alphanumeric data. *If ABC mode is not pressed, the LED is off.  Then the machine is in normal mode. *If ABC mode is pressed once, the LED will blink intermittently a...
