For a high-volume product it makes sense to pay for a fully streamlined die, but that may not be worthwhile for a small-volume product. Reducing shear stress in the land region can be done by increasing the die gap, reducing the extrusion rate, increasing die-land temperature, increasing melt temperature, or reducing melt viscosity.

Extrusion Processes - SlideShare

 · • A small shot of solid material is placed in the die and is impacted by a ram, which causes cold flow in the material. It may be either direct or indirect extrusion and it is usually performed on a high- speed mechanical press. • Although the process is generally performed cold, considerable heating results from the high speed deformation.
