Performance management for Deep Drawing Units: tracing a defect to die, blank or lubricant
In a deep drawing unit a cracked or scratched shell is blamed on whoever stands at the press. Performance management here starts by finding the real cause before judging the person.

Without a fair method, defect reviews become blame. A crack is traced to the operator, though the blank was off size, the lubricant uneven or the die worn. Operators learn to hide defects or run parts that should be stopped. Setters are judged on output alone and rush trials. The crew sees the review as a threat and stops giving the early warnings that would save a batch.
Good practice starts with a short defect sheet that lists blank, lubricant, die and operator, filled in at the press. The crew reviews the sheet weekly, with the supervisor asking what changed. Goals are few and clear: a stable first-piece check, fewer repeat defects, safe habits at the press. Feedback is given by the supervisor in plain words, and praise for early stops is as visible as criticism.
How to set it up
1. Introduce a one-page defect sheet at each press
Columns for part, defect, blank lot, lubricant, die and operator. The operator fills it in when a defect is found, with no penalty for honest entries. Keep the form small enough to fill in with gloves on.
2. Review the sheet weekly with the crew
Fifteen minutes with the supervisor, setter and operators looking at repeat causes. Ask what changed before the defect started. Record one action per cause and who owns it.
3. Set a few goals per role
Operators: first-piece check done, safe feeding habits, clean housekeeping. Setters: trial time and die condition notes. Supervisors: defects traced to cause. Keep goals to three each, so they are remembered.
4. Hold short, regular feedback conversations
Supervisors speak to each person monthly for a few minutes, with one thing done well and one thing to change. for a simple format we can set up.
5. Recognise early stops and honest reports
When an operator stops a press because the draw looks wrong, say so in front of the crew. This keeps defects from running and shows that reporting is valued.
Check these first
Before changing anything, find out what is true today. Use your own records for a defined period and note gaps in the evidence. The review may take longer if records are incomplete or spread across teams.
- Read the last ten defect reports and count how many name a cause other than the operator.
- Ask two operators whether they would stop a press on a doubtful part without fear.
- Check whether setters are judged on output alone or also on die care and trial quality.
- Look at when each supervisor last spoke one to one with each crew member.

Questions owners ask
Make honest reports safe. If the first reaction to a defect is blame, people will hide them. Trace cause first, praise early stops and keep action on the system before action on the person.
Output matters, but a target alone pushes people to rush and cut safety. Pair it with first-piece checks and defect goals, so speed does not beat quality or safety.
Briefly after each tricky die change, and formally every few months. Look at trial time, scrap in trials, die notes and whether they train others.
We set up the interview and hiring process for deep drawing units
Every business interviews, but few have a written process that works the same way for every role and every interviewer. GullyHR designs yours, from the role brief to the offer, trains your managers to run it, and can run it for you on the roles you hand us.
