Mold Making
Mold Making is a specialized manufacturing skill where professionals create precise tools (called molds) that are used to produce plastic, metal, or other material parts. Think of it like making an advanced ice cube tray - the mold is a negative shape that when filled with material creates the desired product. These specialists work in manufacturing facilities and are crucial for mass production of everything from car parts to kitchen containers. It's similar to pattern making or die making, but focuses specifically on creating hollow forms that can be filled with materials to create identical copies of products.
