Injection molding cell

Four injection molding machines over OPC UA in the EUROMAP 77 shape and the dryer, TCUs and chiller they share over Modbus TCP, where a fault in a shared utility reaches every machine at once.

What it simulates

A contract molder's injection molding cell: two Engel victory 150s on eight-cavity PA66-GF30 tools, an Arburg 570 A on PBT and a Husky HyPET 650 on HDPE, with the utilities they share, a central desiccant dryer, two mold temperature control units and a chiller. 8 devices, 158 tags.

The machines publish over OPC UA in the EUROMAP 77 shape and the utilities over Modbus TCP, which is how a real molding shop is wired. A cause in a shared utility only shows when its reading is joined to the machines it feeds, and Litmus Edge does that join.

  • an animated view of the cell, with every machine and utility opening its digital twin
  • cushion shot by shot, peak pressure in every cavity, and the dryer against each resin's limit

What it configures on Litmus Edge

On startup, and it removes exactly what it created when you are finished:

  • 4 DeviceHub devices on the OPC UA Client Advanced driver and 4 on Modbus TCP
  • 4 Digital Twin models with 8 instances
  • 5 Analytics groups: cushion stability, cavity balance, resin moisture, molding performance, cooling utilities

Scenarios you can inject

None of them trips an alarm, because every shot stays inside the machine's own limits.

  • A worn check ring shows in the cushion scatter before any part is short, and stretches the cycle past its quote
  • One cavity freezing off packs light while the shot weight barely moves, and only the cavity pressure sees it
  • A dryer that stops regenerating drops injection pressure on every dried resin at once, while the polyethylene machine stays flat as the control
