I was asked this question yesterday via email…
What should I be looking for when my guys process?
There the 5 things that I always look for:
Rule 1 – Make one process change at a time
Rule 2 – Make significant changes
Rule 3 – If a change does not help, change it back
Rule 4 – Document the process
Rule 5 – Document all changes to the process
These rules apply to injection molding, extrusion, and blow molding alike.
This list seems pretty simple, but I have found that most molders skip at least one or two of these steps whenever they process.
