Metal Model Makers are skilled professionals who create physical models of metal components using a variety of techniques. They may work with a variety of metals, including steel, aluminum, and bronze. Their key job responsibilities include:

1. Fabricating metal components

Metal Model Makers use a variety of tools and techniques to fabricate metal components. These components may be used for a variety of purposes, such as prototyping new products, creating molds for casting, or repairing damaged parts.

• Cutting and shaping metal using a variety of tools, such as saws, shears, and grinders
• Welding or brazing metal components together
• Casting metal components using a variety of techniques, such as sand casting, investment casting, and die casting

2. Finishing metal components

Once metal components have been fabricated, they must be finished to give them a smooth surface and to protect them from corrosion. Finishing processes may include:

• Sanding and polishing metal components
• Plating metal components with a variety of materials, such as chrome, nickel, or gold
• Painting or powder coating metal components

3. Inspecting metal components

Metal Model Makers must inspect metal components to ensure that they meet quality standards. This may involve measuring components to ensure that they are the correct size and shape, and checking for defects such as cracks, voids, or inclusions.

• Using a variety of inspection tools and techniques, such as calipers, micrometers, and gauges
• Documenting inspection results and reporting any defects found

4. Maintaining equipment

Metal Model Makers must maintain their equipment in good working order. This may involve cleaning and lubricating equipment, and performing minor repairs.

• Following manufacturer’s instructions for equipment maintenance
• Identifying and resolving equipment problems
