This applies to both production and mold/die operations. For the layman, this means small, as in hair size small. My average hair diameter is about .10 mm. When you see the cutting tools used to machine such tiny details, you have to ask yourself: “How did anyone ever make this thing?” It looks impossible. Yet there are companies that build plastic injection molds exclusively for such miniature parts. Micro machining is an everyday fact of life. There are also companies that injection mold microscopic plastic parts from these micro machined injection molds. They do it every day of
