A monthly people review for plastic moulding and extrusion units: ten questions for the owner

Owners of moulding and extrusion units read output, rejects and dispatch every week. People come up only when something snaps. The senior setter resigns. Nights collapse during Chhath. A buyer traces a wrong clip in a carton to a packer in her second week. A monthly sitting built on ten standing questions picks up those signals while they are still faint.

1. Who left, from which press or line and shift, and what reason did they give? Paper: leaver register with exit remarks.
2. Which moulds or dies can only one person per shift start? Hot-runner tools, glass-filled jobs and large pipe dies are usual suspects. Paper: matrix footer for each shift.
3. How many press-hours or line-hours sat idle for want of a setter, the crane, a tool from the tool room or a leader for a size change? Paper: idle-time log.
4. How did night attendance compare with days, and who plugged the holes? Paper: muster summary split by shift.
5. Of last month's newcomers, who remains and who has a signed first-week sheet? Paper: joining list and checklists.
6. Who tops the overtime sheet, and did they top it last month too? Paper: overtime totals per head.
7. Which rejects traced to a people cause, such as an untrained purge, a skipped dryer check or a setting changed without a log entry? Paper: rejection register with causes.
8. Which complaints came in, about which supervisor, and which are still open? Paper: complaints book.
9. Which sign-offs happened, such as a large-press mould change, a film size change or robot teach, and which promised training slipped? Paper: training plan against actuals.
10. Whom might we lose next, and what is the plan this month? Paper: names from shift leads, handled privately.
Close: each action carries a single owner and a target day, all checked first at the following sitting.

Each question aims at a soft spot in these units. Two and three find the setters and line leaders the floor leans on, and the hours lost when they are elsewhere. Four and six show whether nights and long shifts keep falling to an identical handful. Five watches the trimming benches and packing tables, where newcomers drift away fastest. Seven connects flash, short shots, black specks, ovality and gauge drift to people causes without blaming whoever stood nearest. Ten forces the talk owners postpone until a resignation letter lands.

• A setter quietly avoiding mould changes on nights.
• A line leader who has stopped updating start-up sheets.
• Packers asking to move off the deflashing bench.
• Heat complaints from the barrel side as summer nights arrive.
• Dryer and material staff skipping checks because one of them is always on leave.
• Operators asking about the next grade and getting no answer.

• Injection presses: question two lands on hot-runner tools, two-shot moulds and the biggest toggle press. Often only one setter trusts the tie-bar clearance there.
• Blow moulding: look for whoever alone can programme the parison profile on jerry cans or drums, and for deflashing helpers who keep rotating out.
• Pipe and conduit lines: size changes, socketing and belling ovens, and the leader who can hold wall thickness on big-diameter dies through a hot afternoon.
• Blown film and lamination: bubble stability, gauge profile and the printer who matches shades, often the most poached people in the estate.
• Tool rooms attached to moulders: polishers, spark-erosion operators and the fitter who spots cores and cavities, who rarely appear on any attendance worry until they leave.

1. 1

   Pick a date that cannot drift

   For instance the first Saturday after attendance is closed. Reviews without a fixed slot fade within a season.

2. 2

   Papers assembled two days ahead

   Whoever handles HR collects each listed paper and circles anything that moved since the previous sitting.

3. 3

   Start from last month's list

   Each action is done, late or dropped. A dropped action needs its reason spoken aloud.

4. 4

   Move briskly through the ten

   Several answers will take seconds. Spend time only where a paper shows change.

5. 5

   Leave with one page

   Actions, owners, target days. A copy goes on the plant head's wall.

• HR or the office: leaver notes, attendance by shift, overtime by person, joining list, complaints book.
• Plant or production head: matrix footers, idle-time log, reject causes from the quality inspector.
• Shift leads: names of anyone unsettled, given privately to the plant head before the sitting.
• Owner: decisions on grade steps, hiring and anything needing money.

Plenty of units have no idle-time log that separates waiting for a person from waiting for resin, and no exit notes at all. Ask the question regardless and record that the answer is unknown. That blank becomes the first action. A few sittings later the paper exists, because the review keeps asking. A written routine like the one in how shift handover should work feeds questions three and seven.

The plastic manufacturing HR hub describes the patterns these questions track. For the leavers side, see why trained press hands drift to the next estate. If gathering the papers is the hard part, HR reporting can pull them from attendance and HR records. To talk about setting up the sitting, sketch your presses and lines on the requirements page.
