A thermoforming unit turns plastic sheet into trays, covers and liners on heated forming machines. Quality rests on setters who read the sheet, the heater and the tool. This is how to staff, train and keep them.
Not sure what you need? Tell us about your business in six short steps and we will come to the first meeting prepared.
Share your requirementsA thermoforming company buys plastic sheet or rolls, heats them until soft, draws them over a tool by vacuum or pressure, then trims the part. A typical floor has forming machines, a tool store, trimming and punching stations, a small quality bench and a packing area. Work runs in shifts, often day and night, because heaters take time to stabilise and stopping wastes sheet. Setters decide the heater settings, forming time and cooling for each tool, and much of that knowledge lives in their heads. Orders arrive in short runs for packaging, auto interiors, appliances or medical trays, so tool changes are frequent. Hot surfaces, trim dust and noisy vacuum pumps make safety a daily matter. For the wider sector, read HR for manufacturers.
These are the places the people side of this kind of business tends to give way. The rest of this page works through them.
HR here has to work for each of these groups, not only the office. The set-up below is written with all of them in mind.
GullyHR runs talent acquisition for permanent roles in thermoforming companies. For each role we agree the job description with you, find and screen candidates against it, and support the offer through to joining. Tell us the role and the number of people, and we start there.
We recruit permanent employees. We do not supply contract or temporary staff.
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.
We agree what the role must deliver, the must-have and nice-to-have skills, and how each will be scored.
Screening call, assessment, interview rounds and decision points, sized to the role and the number of people you hire.
Structured questions for each role family and a rating guide, so two interviewers judge the same answer the same way.
A short briefing for your managers on what to ask, what to avoid and how to give a clear yes or no.
Who approves, how the offer is made, and how candidates are kept informed from first call to joining.
The best setter knows how a tool behaves on a cold morning, and when he is on leave the rejection rate climbs.
One shift changes a tool in forty minutes and another takes two hours, because nothing is written down.
New operators reach over a heated platen or handle hot parts without gloves, and nobody is checking.
Problems with sheet thickness or sag wait till morning, and a whole batch is scrapped.
They are paid least and trained least, yet burrs and edge cracks are what the customer rejects.
Capable people stop learning, and they leave for a unit that lets them set.
A rush order for trays means long hours for a week, then idle hours, and attendance suffers in between.
Sheet waste is counted at month end, so no operator sees what his shift cost.
Start with the topics that matter most here: Learning and Development; Health, Safety and Wellbeing; Performance Management. Then work through the rest. Each topic is written for manufacturing, not in general.
Training planned from need rather than from the calendar.
Induction, records, incident reporting and follow-through.
Goals, reviews and ratings that hold up in a conversation.
How many people, in which roles, by when — and what they will cost.
Structure, reporting lines and who is allowed to decide what.
Requisition to joining, the same way every time.
A first day that is the same for the fifth joiner as the first.
Records, attendance, leave and the day-to-day HR that must simply work.
Salary structure, payroll inputs and a month that closes on time.
Named backups for the roles that cannot be vacant.
Communication, recognition and the conditions people actually work in.
Two routes — one for complaints, one for conduct — kept separate.
Policies a manager can apply, and obligations with owners and dates.
Who leaves, when, why — and which of them mattered.
Resignation to relieving letter, in a defined order.
Records that survive people, and approvals that do not queue.
A short monthly pack management actually reads.
An HR function that runs the same way every month.

Write a setter sheet for each tool, pair an assistant with the setter on every change, and let the assistant set the simpler tools first. Skill spreads when it is written and practised.
Start with hot-zone rules and loading, then trimming, then watching a tool change, with a buddy and a sign-off at each step. Allow several weeks before a solo shift.
Within limits on the tool sheet, yes, once they are signed off. Locking everyone out keeps good people from growing.
Plan overtime and rest days in advance, share the load across shifts and avoid asking the same crew every time. Confirm working hour limits with a qualified professional.
Look at supervision, handover notes and sheet storage before blaming people. A named senior person on nights usually changes the picture.
We would start with the setter ladder, tool change records and the night shift handover, then the safety walk at the hot stations. Scope, timing and fees are written down so you know what you are buying.
