The situation
Cavity wax is corrosion protection sprayed into closed body sections. The process needs coordinated motion, flow and position sensing, and it sits inside a production line where a fault means stopped bodies.
What it delivers
A spray line the plant runs and maintains itself, with the drives, sensing and I/O on one network and one set of documentation.
What we built
- 01Full electrical design for the wax cavity spray system
- 02Mitsubishi VFDs communicating over EtherNet/IP
- 03Sensors, encoders and on-machine I/O networked over EtherNet/IP
- 04Pump skid controls with pressure and level monitoring
- 05Commissioning and onsite installation
