Workplace health, safety and wellbeing for Injection Moulding Units: hot presses and tired night shifts
Moulding presses combine heat, hydraulics and heavy moulds. Most injuries come from routine moments such as clearing a jam or changing a mould, and from tired people on long night shifts.

The usual stories are a hand caught while removing a part with the press not locked out, a burn from a hot barrel or a purge, a strain from lifting a mould or a bag of granules, and a slip on a spill of oil. They happen when a shift is rushed, when a new operator has watched but not been shown, or when a guard is bypassed to keep the cycle going. Night shifts add tiredness, poor light and fewer supervisors.
Good practice begins on the floor, with a walk of every press to mark guards, interlocks and floor hazards. Safe ways to clear a jam and change a mould are written as short, illustrated steps, and the setter teaches them. Near misses are noted without blame. Night workers get proper breaks, a place to rest, and a supervisor who walks the floor, and heat and noise are treated as real working conditions.
How to set it up
1. Walk each press and list its hazards
Mark guards, interlocks, hot surfaces, hydraulic lines, and floor spills at every press. Ask the operator what scares them. Fix what can be fixed quickly and note the rest.
2. Write the safe way to clear a jam
One page with pictures: stop the press, lock it out, wait for cooling, clear, check, restart. The setter walks every operator through it and signs the sheet.
3. Make mould change a shared, planned job
Agree who lifts, who guides and who signals. Use proper lifting aids and keep a clear path. A rushed change is where hands and backs are hurt.
4. Record near misses and discuss them weekly
A simple note in the shift log is enough. Read the notes at the weekly meeting and fix the cause. Do not hunt for someone to blame. See workplace health, safety and wellbeing.
5. Look after the night shift
Set breaks, rest space, water, and a supervisor round every few hours. Ask night operators what is hardest and act on at least one point each month.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Walk three presses and count missing or bypassed guards.
- Read the shift log for the last month and count injuries and near misses noted.
- Ask an operator to explain how to clear a jam safely and compare with your written step.
- Check whether anyone has lifted a mould by hand in the last month.

Questions owners ask
The shift supervisor owns it day to day, the setter owns the state of the press, and the owner or plant head owns the standard. Name each in writing so a problem is raised and fixed, not passed along.
Find out why. Usually it is to save seconds on a cycle or because the guard blocks the part removal. Fix the guard design where possible, explain the risk plainly, and deal firmly with deliberate bypass.
Water, shade, breaks, proper footwear and some noise relief make a visible difference. Add a way for operators to raise concerns with a supervisor without fear. Small, regular acts matter more than a large one-off programme.
