# Foundry Moulder

Foundry moulders manufacture cores for metal moulds, which are used to fill a space in the mould that must remain unfilled during casting. They use wood, plastic or other materials to create the core, selected to withstand the extreme environment of a metal mould.

## Core workflow

1. Clean and smooth molds, cores, and core boxes, and repair surface imperfections.
2. Move and position workpieces, such as mold sections, patterns, and bottom boards, using cranes, or signal others to move workpieces.
3. Sprinkle or spray parting agents onto patterns and mold sections to facilitate removal of patterns from molds.
4. Position patterns inside mold sections, and clamp sections together.
5. Position cores into lower sections of molds, and reassemble molds for pouring.
6. Sift and pack sand into mold sections, core boxes, and pattern contours, using hand or pneumatic ramming tools.
7. Cut spouts, runner holes, and sprue holes into molds.
8. Lift upper mold sections from lower sections, and remove molded patterns.
