Profession moulding machine operator

Moulding machine operators operate machines that are part of the production process of moulds for the manufacturing of castings or other moulded materials. They tend the mouldmaking machines that use the appropriate materials such as sand, plastics, or ceramics to obtain the moulding material. They may 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 moulded products such as ferrous and non-ferrous metal castings.
