ENGEL and Koch integrate dosing and mixing on injection molding machine
Source:Adsale Plastics Network    Editor:JK    Date:16.May.2022

ENGEL AUSTRIA and Werner Koch Maschinentechnik have jointly developed an OPC UA interface for the integration of machines for mixing and dosing thermoplastic materials on injection molding machines.


Dosing and mixing units by Koch can now be integrated with the CC300 control unit of the ENGEL injection molding machines via OPC UA and operated via the control panel on the machines. With its service-oriented, platform-independent and freely scalable structure, OPC UA offers both flexibility and a high degree of data security.


Today, the mixing ratio of the base material, additives and master batches are still set manually in many applications. To do this, a separate control unit is typically required on the injection molding machine.


ENGEL and Koch enable the integration of dosing and mixing units with the injection molding machine control unit via OPC UA.

The integration of dosing and mixing units with the machine control unit offers the advantage of being able to directly transfer the parts dataset, and with it the recipe, directly to the dosing unit on mounting the mold in order to automatically configure the mixing ratio.


The dosing process is centrally controlled via the machine display, removing the need for the additional control unit. Alerts from the dosing and mixing unit are also output via the CC300 machine panel.


As a result, dosing becomes a more convenient experience for production employees, and the risk of input errors is reduced. Storing process data together also makes the production batch easier to trace.


ENGEL injection moulding machines can currently use OPC UA to talk to a large range of peripheral devices. They include temperature control units, hot runners and LSR dosing systems, for which EUROMAP recommendations also exist.


Dosing and mixing units for thermoplastics have now been added. Standardized interfaces also simplify communication with the production cell independently of the manufacturer.
