GRP Mixing Control System


This system controls the sequence for a Glass Reinforce Plastic (GRP) mixing system at an enclosure production company.


The system controls the batching of resins and powders and informs the operator of the system status.


A Mitsubishi FX2n PLC is used for the sequence control while an Allen-Bradley PowerFlex 700 is used for the speed control of the 45 kw mixer motor.


A Hakko HMI (Human Machine Interface) is used for the operator interface. The software was written using GX-Developer.
