Automated molding and metering in the manufacture of plastic parts with robot cell and index table station


In future a wide variety of parts will be molded using a KUKA robot and an index table station. The contract included:

  • Planning of hardware and safety systems
  • Electrotechnical design of the metering system and the robot cell with index table station
  • The software development for the HMI and robot

At the same time we helped the customer, who was responsible for building the control cabinet and programming the PLC, to perform electrical and control system-related tasks.


Plastics technology


With additional option packages for the KUKA robot, a flexible system for metering and sealant application was created, which is perfectly adapted to suit the small batches to be produced and the special applications. As per the customer's wishes, the metering system and the robot can be operated using a single visual display. This allows quick and simple recipe management when changing production process. Due to the open program structure, the end user can add program expansions for the robot at any time. The erler team meticulously accompanied the commissioning of all the system components whose working and safety zones are safeguarded by the robot option package SafeOperation.
