Water tanks, bins, crates, play items and containers are formed by heating powder inside a rotating mould. This page covers oven crews, mould handling, heat stress, long cycles and the skill of judging a good part.
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 rotational moulding company makes large hollow plastic items such as tanks, bins and containers. Workers weigh plastic powder, charge the mould, close it, load it into an oven where it rotates on two axes, then cool and open it. A full cycle takes a long time, so one oven crew handles several moulds per shift and waits between steps. Heat, hot moulds and heavy arms are part of the day. After moulding, parts are trimmed, drilled, fitted and checked. A trained operator can read wall thickness and colour by eye and ear; a poor judge produces thin walls or burnt parts.

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 rotational moulding 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.
Working near hot ovens and moulds drains energy, and summer sees dizziness and absence.
Colour, smell and sound tell an experienced operator when to pull a mould, and trainees rely on guesses.
Hot mould parts, clamps and heavy arms cause injuries, and minor ones go untreated.
Wrong powder weight gives thin or thick walls, and nobody can say who weighed it.
Waiting time leads to phone use, early pulls and lapses at the oven door.
Tanks and bins are awkward, and uneven lifting hurts backs and drops parts.
Cracked seams, vents and cooling faults are known to one fitter, and his absence idles an oven.
Mixed-up powders show as colour patches in finished products and in returns.
Start with the topics that matter most here: Health, Safety and Wellbeing; Learning and Development; Employee Administration. Then work through the rest. Each topic is written for manufacturing, not in general.

Provide water and shade, rotate people away from ovens, adjust summer shifts and watch for early signs. Ask a qualified professional about workplace health duties.
It varies, but a clear ladder with supervised cycles shortens it. Judge by demonstrated skill, not months.
Record weights, check wall thickness early and coach on patterns. Do not blame without a record.
Set safe limits and use team lifts or aids. Ask a qualified professional about lifting guidance.
Assign tasks between steps, such as trimming and cleaning, and plan oven loading to reduce gaps.
We would ask about heat at the ovens, how operators learn and how weights are recorded. A good first job is a heat routine and operator ladder. After a first talk, scope and fee are put in writing.
