This is the part of manufacturing that often gets overlooked, the moment where process control either proves itself…or doesn’t.

In this clip, units are exiting the splitter and moving toward final QC before the cuber.

At this point in the process, we’re paying close attention to:
• Split face consistency and texture uniformity
• Dimensional tolerances post-split
• Edge integrity and corner breakage
• Alignment and spacing as units transfer downstream

The goal isn’t just to “catch defects,” but to understand process behavior in real time. Small changes upstream—moisture content, compaction, splitter alignment—show up here.

By the time product reaches the cuber, it should already be within spec. This final QC is less about sorting and more about verification that the system is running as intended.
