Learning and development process for Sand Casting Foundries: teaching moulding before the old hands retire
Hand moulding skill is leaving with older workers, and few young people want it. A learning process turns what seniors know into steps a new moulder can follow and be checked on.

Share your requirementsWhy learning and development process matters in sand casting foundries
In many sand foundries the best moulder has never taught anyone formally. A young helper stands beside him, sweeps sand, and is allowed to try after months. Some learn, many drift away because nothing tells them how far they have come. Patterns, sand mixes and core boxes change with each job, so what is learnt on one casting does not carry over without explanation. When the senior leaves, the know-how goes with him.
A workable learning process is small. List the tasks in moulding and core making from simple to hard: ramming a flat mould, setting a core, venting, gating a new pattern. A senior shows each task, the learner repeats it, and the senior signs it off. Short sessions on sand properties, pouring discipline and pattern care run on slow days. Progress is visible, and each step has a small reward.
How to set it up
1. List the tasks in order of difficulty
Write down moulding, core making and sand handling tasks from the easiest to the hardest, using the words your floor uses. Ask two seniors to correct the list.
2. Pair each learner with a named senior
Choose seniors who are patient and give them a reason to teach, such as an allowance or a status title. Make time for it, for example the first hour on slow days.
3. Teach with a show, try, check pattern
The senior does the task and explains why, the learner repeats it, and the senior checks the casting or mould. Record the result on a simple card that the learner keeps.
4. Add short sessions on sand, patterns and pouring
Use slow periods for fifteen minute talks on sand moisture, pattern handling and safe pouring. Keep a log of who attended. Training design can shape these into a repeating plan.
5. Review progress each quarter
Sit with each learner and senior, look at the task card and decide the next step. Link completed steps to a pay rise, so effort is recognised.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- List your moulders by age and note how many will retire in the next few years
- Count how many helpers joined in the last two years and how many can now mould alone
- Ask a senior moulder what they have taught anyone in writing or by demonstration
- Check whether new learners have a record of tasks they have completed

Questions owners ask
Yes, if the steps are small and the senior has time. Start with sand preparation and simple moulds, and move up by sign-off. Many people learn well when they can see the next step clearly.
This is common. Give them a defined role as trainers, with recognition and a pay step, so teaching raises their standing. Show that the foundry needs both experienced and new hands.
Use fixed short slots, such as the first hour on a quieter day, and keep sessions practical. A little regular practice beats a long course that is cancelled when orders spike.
