Presses run round the clock turning granules into caps, housings, crates and parts. This page covers setters, operators, quality checkers, night shifts and the knowledge that keeps scrap low.
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 requirementsAn injection moulding shop runs presses, often day and night. A setter fits the mould, sets temperature, pressure and cycle, and gets the first good part. Operators then pull parts, trim, inspect and pack. Colour changes, material switches and mould changes interrupt output, and a good setter can restore good parts in minutes where a weaker one takes hours. Heat, hydraulic oil, heavy moulds and moving platens bring risk. Customers want steady supply and low rejection, so errors on night shift hurt delivery the next morning.

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 plastic injection molding. 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.
Good settings for a mould and material are remembered, not recorded, and a setter leaving takes them along.
Rejection and idle time climb after dark when seniors are away and a trainee runs two presses.
Heavy moulds and tight schedules make changeovers a risky job for those who have never done one.
Short shots, flash and sink marks are found late, and nobody knows which shift or operator was running.
Burns, pinches and oil slips are treated as part of the job until a serious injury occurs.
Contract workers move between units, so a skilled hand cannot be built up over a few weeks.
Production wants volume, quality wants checks, and operators get conflicting instructions.
An operator wishes to become a setter, but nobody offers a plan, so he looks elsewhere.
