Onboarding and probation for Plastic Component Makers: settling assembly and sorting staff early
Assembly and sorting teams of small plastic parts turn over fast. A good first week and a clear probation review cut early exits and stop new people from sending the wrong part to a customer.

Share your requirementsWhy onboarding and probation matters in plastic component makers
New assembly staff are placed at a bench, shown the job once and left to match the sample. Within days they are sorting good parts from rejects without knowing why one flash mark matters and another does not. A mix-up of two similar parts goes into one bin, and the lot is packed. Some leave in the first two months, because the work is repetitive, the supervisor is busy and nobody asked if they understood.
Good onboarding gives a first-day walk through the part's journey: moulding, trimming, inserts, assembly, inspection, packing and customer. The new person sees the approved sample and a limit sample showing good and bad. A buddy stays for the first week. Quality checks on their work are frequent early and then reduced as they sign off. Probation reviews at one month and the end cover accuracy, attendance and how they feel about the work.
How to set it up
1. Plan day one around the part and its customer
Show what the part is used for, why the fit matters and what happens if a bad one gets through. A person who knows the use looks harder at the part.
2. Show the limit sample and the approved sample
Put good, borderline and reject parts side by side at the station, with a short note on each. Let the new person handle them and ask questions.
3. Assign a buddy for the first week
The buddy sits beside, checks the first lots and answers questions. Make the buddy someone with clean quality records, not simply the nearest person.
4. Check early work closely, then less
Inspect the new person's output every hour on day one and at set points after. Record what is found. Reduce checks as the person signs off on each task.
5. Hold a review at one month and at the end of probation
Cover accuracy, attendance, how the person finds the work and what they need. Record the outcome and share it. Ask what almost made them leave.
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.
- Look at how many recent assembly joiners left early.
- Ask the last three joiners what they did on day one and what they wish they had known.
- Check whether each station has a good, borderline and reject sample.
- Count mix-ups traced to new staff in the last year.

Questions owners ask
At least the first week, and a lighter check for a month. The exact time depends on the part's difficulty. Judge by the quality checks: when the new person's work is consistently good, the buddy can step back.
Not unsupervised. Start them on simple, low risk sorting with a trainer checking. Let them move to inspection once they can tell good from reject on the limit sample without help.
Notice early and talk to the person. Some can move to packing or material handling, which differ in pace. If no role fits, it is better to part on good terms at one month than to drift to the end of probation.
We set up the interview and hiring process for plastic component makers
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.
