Rubber compounds are mixed, shaped and cured into belts, tyres, sheets, mats and moulded goods. This page covers mixing mill crews, press operators, heat and fume exposure and the compound know-how held by a few senior hands.
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 rubber factory begins with compounding. Workers weigh polymer, fillers, oil and chemicals, then mix them on mills or in internal mixers. The compound is rolled, cut, shaped and cured under heat and pressure in presses or autoclaves. Finishing includes trimming, buffing, testing and packing. Black dust, chemical smells, heat and heavy mixers define the shop floor. Compound recipes and mixing sequences determine product quality and are known to a few senior hands. Orders vary by product line, and curing times keep presses tied to a fixed rhythm. Related reading: 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 rubber manufacturing. 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 sequence and timing of mixing is carried in memory, and a departure damages quality for months.
Carbon black, chemicals and curing fumes are present, and masks and extraction are used unevenly.
Mills, presses and hot products tire workers, and absenteeism rises in summer.
A missed chemical or wrong weight is found only after cure, and a whole batch goes to scrap.
Cure time, temperature and loading differ by hand, and under-cured products reach customers.
Nip points on rolls and open mixers cause serious injuries, especially for rushed or new workers.
Test results delay lots, and floor staff feel judged by the lab.
Skilled mill and press hands leave for slightly better pay, and trained knowledge walks out.
Start with the topics that matter most here: Health, Safety and Wellbeing; Career and Succession Management; Retention and Attrition Management. Then work through the rest. Each topic is written for manufacturing, not in general.
Induction, records, incident reporting and follow-through.
Named backups for the roles that cannot be vacant.

Limit access, write procedures, train backups and use confidentiality terms drafted by a qualified professional.
Dust and fume exposure may need medical review. Ask a qualified professional what applies.
Use labelled containers, a second check and a log of who weighed. Coach on patterns.
Use a ladder with posted cure cards, supervised loading and a test on a real job.
Often pay, heat and unclear growth. Ask exiting staff and compare with nearby units.
We would ask who holds compound know-how, what protects mixing room staff and how presses are run. A good first job is a compound record and safety routine. After a first talk, scope and fee are put in writing.
