In the world of manufacturing, an extrusion die is a precision-engineered tool made from high-strength tool steel that functions as a mold for shaping metal or plastic. It is essentially the template that determines the cross-sectional profile of the final product.

Core FunctionalityThe process is often compared to squeezing toothpaste out of a tube. In industrial extrusion:

A heated billet (usually aluminum, copper, or steel) is placed in a container.

High pressure is applied by a press ram.

The material is forced through the die opening, taking on the exact shape of that opening as it emerges on the other side.
