A mold maker creates wax, sand cores, or molds used in the production of metal castings.

Are you artistic and detailed? Would you rather work with your hands than sit in an office? If so, a position as a mold maker will offer you the perfect mix of design and hands-on work. You’ll work with designers and engineers to construct molds that are used throughout the manufacturing process.

Mold makers work primarily in two different areas. The first is using computer-aided design (CAD) software to create technical drawings of molds and products. The second is the production floor, where you’ll physically perform machine setup and put the molds together and fill them, or operate machines that do so. You’ll work with different chemicals and materials, including molten plastic and metal, so you’ll need to follow safety codes and procedures very carefully. Assembling or handling the molds might require a high level of physical strength. Mold makers are required to take a project from CAD design concepts to actual molds.

You’ll need other skills as a mold maker, such as reading technical drawings and knowing which tools to use and the processes behind repairing basic machinery. You’ll need a sharp eye for detail in order to spot imperfections in molds and finished products.

While mold maker is considered an entry-level position, potential employers will be impressed by previous experience. Look for training programs or apprenticeships that offer an opportunity for hands-on work, or an associate’s program at your local community college. Proficiency in technical drawings reading and CAD software is also a great way to stand out.
