Onboarding and probation for Rubber Moulding Units: the first week at hot presses
A press operator near hot plates and steam needs to know the dangers and the method before the first shift. A planned first week and a clear probation protect new joiners and the parts they make.

Share your requirementsWhy onboarding and probation matters in rubber moulding units
Operators learn by watching the one next to them, including the shortcut on cure time and the way they reach across a hot plate. New joiners are handed a press and told to follow. A deflasher joins at a table and leaves after a week because nobody explained the task or the pay. Probation ends by silence. Pay is often per press or per piece, so new joiners pick up the rush before they pick up the habits.
Good looks like a first day with a floor walk, safety talk, gear and a named buddy. The first week uses a checklist: hot areas, stop button, load, time, open, remove, check. Operators are not asked to run alone until a senior signs. Probation has written tasks and a short review with a clear yes, extend or no and a reason.
How to set it up
1. Plan the first day
Floor walk, safety talk, gear fitted, buddy named. Show the hot plates, steam points, stop buttons and first aid before any work. Ask the person to repeat what to do in an emergency.
2. Use a first week checklist
Load, time, open, remove, check and handover. Mark each as shown. A new operator should not run alone until the senior signs the sheet.
3. Teach cure time as a rule
Explain why the time is fixed and what happens when it is cut. Show a spoiled part next to a good one. Make cure time part of the probation tasks.
4. Brief deflashers on task and pay
Explain the task, the standard, how pay is counted and who to ask. Clear expectations at the start reduce early exits.
5. Hold a short probation review
Meet the person, supervisor and buddy before the end date. Decide confirm, extend or end, and record the reason. See employee onboarding process for a full flow.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Count joiners in the last quarter who left in the first fortnight and their sections.
- Read the last five probation files for written tasks and a decision.
- Ask two new operators what they were told about cure time and hot plates.
- Check how many operators started running alone without a signed checklist.

Questions owners ask
Use a short checklist, a patient buddy and real work from day one on a simple part. Add tasks one by one. Quick teaching works when it is planned, not when it is rushed.
Often because the task, pay and standard were never explained, and the work is repetitive. A clear briefing, a fair rate and a friendly buddy fix many early exits.
Long enough to see several mould changes and shifts, with written tasks. Extend rather than confirm if the tasks are not yet shown safely.
