The Rhombus Factory Information System supports in-cycle assembly.

For example you might be moulding large automotive parts with a cycle time of 50 seconds.  During the machine cycle, the operator rivets brackets to the moulding from the previous cycle of the machine.

There is a bill of materials for each operation, so for this operation you would specify both the polymer and the brackets and rivets needed for the assembly.

The system will then prompt the operator to record the input tins of both polymer and components to give full material traceability for each output tin.

You can tell the system which raw materials are used in the moulding process, and which are for the assembly process.  Then, if you have to scrap a moulding before assembly, the system will not backflush the parts for the assembly, since they were not scrapped with the moulding.
