Blow moulding units make bottles, cans and drums by inflating hot plastic inside a mould. Output looks simple, but wall thickness, weight and leak faults depend on setters and operators who watch every cycle.
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 blow moulding unit makes hollow plastic products such as bottles, jerry cans, drums and toys. Plastic is melted and formed into a tube, called a parison, which is clamped in a mould and inflated with air, cooled and trimmed. Small bottles run on fast machines with a few workers per line, and large drums run on slow machines with heavy handling. Orders come from brand owners, chemical firms and packers, as monthly schedules with strict weight and neck-finish rules. A setter adjusts the parison and cooling to keep the wall even, and operators trim and inspect each part. See also HR for manufacturing.
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 blow moulding units. 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.
Parison settings and cooling vary by container, and the best setter keeps a sheaf of notes only they understand.
A thin wall or a bad neck finish passes a casual look and shows up when the customer fills the bottle.
Handling large containers and trimming flash by hand cause strains and burns, and good workers are hard to retain.
Weighing, tapping and visual checks happen when the supervisor watches, and slip when the supervisor does not.
Utility staff and setters are blamed for stoppages that begin elsewhere, and people argue about causes.
Machines run steadily through the night, and staff doze at the trimming bench when no one is watching.
Start with the topics that matter most here: Learning and Development; Performance Management; Health, Safety and Wellbeing. 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.
How many people, in which roles, by when, and what they will cost.

Before changing anything, find out what is true today. Work through the checks using a recent operating period. The time needed depends on the records you hold; note missing evidence and use the findings to choose a priority.

Recognise the skill with a grade and pay, ask the setter to train a second person and avoid making every breakdown the setter's problem.
Set timed checks that are recorded, with a clear reaction plan if a result is out. Operators follow a routine better than a reminder.
Rotate tasks, supply protective gear and set a simple lifting method. Report strain complaints early so they are not hidden.
Agree a named owner for each utility, with a log of faults. When ownership is clear, blame between teams falls.
Some units do. Keep the briefing short and the checks clear, and check the terms with a qualified professional.
We would ask your setter to write down three mould settings, look at how weight and leak checks are recorded and watch the night trimming bench. A good first piece of work is a setting sheet routine and a timed check schedule. Scope is agreed in writing afterwards.
