A green sand line pays its moulders per box. Within a month the box count climbs and everyone is pleased. Then the machine shop returns a pallet of pump bodies with sand inclusions and gas holes. The moulders' pay did not move by a rupee, because their count stopped at the box. The cost landed on the machining bench and on the owner.
So, should a casting unit pay on output? Yes, if the count is of castings that pass, and only where a reject can be traced back to whoever made it. Most units do better with a base wage set by grade plus a bonus on good parts. Safe working should be a condition of that bonus from the first day, not a later patch.
What output pay does well
Paying by count makes effort visible. It rewards the hand who turns up every shift and keeps a steady rhythm. It suits repetitive tasks with a clean unit: shell cores off a core shooter, small castings through a grinder, loads through the shot blast. It also gives a supervisor something factual to discuss, instead of a vague sense that the night crew is slow.
How it goes wrong at the mould and the ladle
- Per box: a hand moulder rams fewer passes and skips a vent. Drops, scabs and blowholes appear after pouring, on someone else's shift.
- Per shot: a die casting operator trims spray and dwell time. Soldering, flash and porosity surface at the trim press or the leak bench.
- Per tonne poured: the pouring gang hurries the ladle between boxes. Metal splashes, the last moulds get cold metal, and misruns follow.
- Per piece fettled: a grinder races through a crate and misses a hairline crack, or cuts into a wall that was already thin.
- Per clean injury record: people stop reporting small burns and near misses, so the hazard stays and the bonus pays for silence.
Two tests that decide the design
First, traceability. If a reject found at machining or by the buyer can be tied to a moulder, a die or a shift, individual output pay can be fair. A chalk number on the casting, a stamped die code or a heat number on the tag makes that possible. Without any mark, an individual count is blind, and a shift or crew bonus is the honest choice.
Second, who does the work. Pouring and knockout are gang jobs; one weak link spoils the whole line. Paying those people one by one sets them against each other at the ladle. Core making, die tending and fettling small parts are closer to solo work, so individual counts can hold there.
Section: hand moulding bay, die casting cell, core shop, pouring gang or fettling.
Unit counted today: box, core, shot, casting or kilogram ground.
Can each unit be tied to one person, one crew, or only the shift?
Where are rejects found: knockout, fettling, inspection, machining or the buyer?
How late is a reject known: same shift, next day or next week?
Proposed count for bonus: accepted castings after the last internal check.
Safe-habit gate: gear worn, ladle path clear, tools dry at the furnace, seen by the shift lead.
Base wage: fixed by grade and paid whatever the count.
Review date: when scrap, complaints and overtime are compared with the old scheme.A pattern many units settle on
- 1
Fix the base by grade
The base pays for the skill level a person has been signed off at. It does not swing with the day's count, so a bad melt does not punish the moulders.
- 2
Count good castings, not attempts
Traced rejects come off the person's count. Rejects nobody can trace come off the shift's count, which gives everyone a reason to mark their work.
- 3
Make safe habits a gate
The shift lead watches for named habits, such as face shields down at tapping and no damp scrap near the bath. The bonus is paid when they are kept.
- 4
Pay gangs as gangs
Pouring and knockout crews share one bonus split by grade. They then police each other's pace in the direction you want.
- 5
Show the count every day
A board at the time office lists accepted castings by shift and section. Disputes are settled weekly, while people still remember the heat.
- 6
Review after one quarter
Compare scrap, buyer complaints and overtime with the months before. Adjust the rules openly rather than quietly changing a rate.
Questions that follow
Should fettlers be on piece rate? Only if every crate is checked after grinding and missed cracks come back to the grinder. Otherwise pay by grade and add a reward for faults caught, so the bench is paid for finding problems rather than hiding them.
What about new hands still learning? Keep learners off output pay until sign-off. A trainee chasing a count near molten metal gets hurt or gives up. Pay the base for their grade and raise it as each task is signed off.
Does night count the same as day? Night crews often lose time to lining patches, furnace start-ups or waiting for power. Count accepted castings per available hour, or agree a separate target, and pay any night allowance apart from the bonus.
What if a buyer rejects a batch after the bonus is paid? Carry the deduction into the next month's shift count, explained on the board. Retrospective cuts to one person's pay, weeks later, breed more anger than any scrap.
Taking it further
Read how output pay pushes people past safe practice for the safety side, and incentives that reward quality for scheme shapes. Grade ladders and bonus rules are what our reward design service builds. Our foundry and casting overview places this problem among the other four the trade faces.
