Profession mouldmaker

Mouldmakers manually create moulds for the production of metal products. They mix sand and hardening materials to obtain a specialised mixture. They then use a pattern and one or more cores to produce the right shape impression in this material. The shaped material is then left to set, later to be used as a mould in the production of ferrous and non-ferrous metal castings.
