Purpose: A process flow diagram is a visual representation of the flow of a manufacturing process as well as the associated quality control checkpoints. Specific symbols are used to represent manufacturing processes, inspection points, decision points, documents, loops, and their interactions.
A process flow diagram shall include:
- A review of the process flow of the given part starting with raw material and moving through to shipping of the finished goods.
- Document all major manufacturing processes, quality check points, decisions, documents, and loops of the given part on a flow diagram.
- Review the flow diagram and ensure the flow diagram matches the flow of the specific part.

Recognizing seal feedability problems during the production process often occurs too late for a simple solution. That’s why we created a video that outlines exactly what you need to be on the lookout for.
