Pay for output can push people past safe practice: a fix for foundries

A moulding crew on a per-box rate stops placing weights on the cope for small boxes. Clamping takes a minute, and minutes are money. One afternoon the metal lifts the cope during the pour, a runout spreads across the floor, and a pourer's boot catches the edge of it. The rate card did not tell anyone to skip the weights. It simply paid more to those who did.

• Moulding: weight blocks and C-clamps left off, box pins not seated, vents skipped, a soft-rammed box poured anyway because remaking it costs the count.
• Melting and pouring: ladles used before preheat, damp scrap or skimmers brought near the bath, ladles overfilled to save a trip, the sprue cup missed and metal splashed over the flask bars.
• Die casting: light curtains taped, trim press two-hand controls wedged, guards left open, die spray cut short to trim seconds off the cycle.
• Knockout: boxes broken out before the casting has set, so hot metal and sand spill onto the grid.
• Fettling: grinder guards removed for reach, and heavy castings turned by hand instead of with the hoist.

Burns and crush injuries are the direct cost, along with the stoppage and inquiry that follow each one. Scrap is the second. A rushed die cycle shows up as porosity at the leak test, and a cold ladle gives cold shuts and misruns. Then there is the human toll. Under a pure output scheme the careful moulder and the steady pourer earn the least. They notice, and they move to units that pay for grade and skill. Others leave after a near miss they do not want to repeat.

Piece rates in foundries were usually set long ago on a count that was easy to measure: boxes moulded, shots fired, tonnes poured. Safety steps were never priced into that count. As orders tighten, supervisors are judged on the same count, so they look away from the shortcuts. Nobody decides to trade safety for output. The scheme makes the trade one minute at a time.

• Set last quarter's highest earners beside the burn, spill and near-miss register. Do the same names or crews appear?
• Watch the closing days of a month, when the count matters most. Note which steps vanish.
• Ask pourers privately how often a ladle goes into service without full preheat.
• Test every interlock and light curtain on the die machines without warning.
• Compare scrap and rejects per crew with output per crew.

1. 1

   Keep a fair base by grade

   Most earnings should come from the grade a person holds, so the bonus is an extra, not the rent money. People under rent pressure take risks.

2. 2

   Count good castings, not boxes poured

   Pay on castings that clear fettling and inspection. A rushed box that scraps earns nothing, so rushing stops paying.

3. 3

   Price the safe steps into the standard

   Set the expected count with preheat, weights, clamping and die spray already included. Doing the job properly should not lower anyone's number.

4. 4

   Add a safety gate

   The bonus is paid only if the crew's checks were done and no unsafe act was seen in the period. See the gate template below.

5. 5

   Pay crews where the work is shared

   Pouring and moulding are team jobs. A crew bonus makes each member watch the others' shortcuts as well as their own.

6. 6

   Protect the stop

   Anyone may stop a pour or a machine for a safety reason, and the lost minutes are never deducted. Say it in writing and honour it publicly.

7. 7

   Review with the crew every month

   Show the count, the scrap and the gate result together. Adjust the standard if it proves too tight to work safely.

Ladle preheat logged before every pour this period: yes / no.
Mould weights or clamps on every box of the listed sizes: yes / no.
Interlocks and light curtains found working at every surprise check: yes / no.
Full protective kit worn at every observation round: yes / no.
No knockout before the set time on the mould card: yes / no.
Unsafe acts observed this period, with date and observer.
Near misses reported: listed for learning only, never a reason to withhold pay.
Gate met: bonus paid / gate missed: bonus held, reason explained to the crew.

Unsafe output pay is listed with four sister problems on our foundry people hub. Base, bonus and gate are designed together in our reward and pay structure work. The broader question of pay basis is covered in choosing between piece and time rates. For the quality side of the formula see incentives that reward quality in casting units. Die casting safety habits are covered on the aluminium die casting safety page. To start, send us your current scheme.
