Foundry Mold and Coremaker
Entry level, learned on the jobStart as a trainee and learn to make and form sand or wax cores and molds used for metal castings, following specs and safety rules.
Where it can lead
Molding Machine Setter
1-3 years of experience firstMove to running and setting up the machines that make molds and cores, which takes more technical knowledge and troubleshooting.

What you can do now
Ideas for high school and college students.
In high school
- Take shop or metalworking classesHands-on practice with tools and materials gives you a head start on the skills foundry work depends on.
- Take math and physical scienceMeasuring, reading specs, and understanding how metal cools and holds shape all rely on these subjects.
- Join a technical club or team, such as robotics or FFABuilding things with a team teaches you to follow plans, fix problems, and work safely with tools.
- Get a starter job at a local shop, farm, or plantAny job where you follow instructions and work with your hands shows employers you are reliable and ready to learn.
- Ask a local foundry or manufacturer about a job shadow or tourSeeing the work up close helps you decide whether it fits you and may lead to a first job.
In college
- Take a manufacturing, materials, or metallurgy courseLearning how metals and sand or wax behave when cast gives you a stronger base for foundry work.
- Look for a summer job or internship at a foundry or manufacturerReal factory experience helps you stand out and learn the day-to-day work before you graduate.
- Get a welding or safety certificationShort hands-on certificates show employers you have practical, safety-minded skills.
- Join a campus engineering, manufacturing, or trades clubWorking on team projects builds problem-solving and communication skills that help you move up.
- Take a community college certificate in foundry or casting technology if one is nearbyA focused certificate can give you more technical knowledge than a general diploma and may speed up your first job.
Tips for getting started
- Take shop, welding, or manufacturing classes and any math that covers measurements and geometry, since accurate measuring matters in this work.
- Look for a part-time or summer job at a manufacturing plant or machine shop to get used to a factory floor and its safety habits.
- Learn basic workplace safety, especially around heat, molten metal, and heavy equipment, because employers value people who work safely.
