About the work

Walk me through how you'd develop a process for a new injection mold from first shot to a stable process.

Parts are coming out with short shots. What are the possible causes, and how do you narrow them down?

What they are checking: Whether they write clear, practical steps and test them with operators, as they will with the IM engineer.

How does material drying affect part quality, and how would you check it?

What they are checking: Whether they understand moisture-related defects and check dryers instead of only adjusting the press.
