What's the word for something that's shaped through a hole?

Scenario: I am pushing clay through a hole, and on the other side it is coming out as a cylinder.

What is the correct term to describe it coming out of that hole?

Solution 1:

As the comments suggest, the process is "extrusion".

Extrusion (from Wikipedia)

Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections, and to work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms parts with an excellent surface finish.
