Indirect extrusion, which is also called backward extrusion, is used to produce hollow shapes with the inside diameter defined by the male punch and the outside diameter controlled by the female die.

In this guide, we will explore the principles of plastic extrusion design and tooling, offering insights into how manufacturers create efficient, high-quality extrusion processes.

The extrusion process has been likened to squeezing toothpaste out of a tube. When pressure is applied at the closed end, the paste is forced to flow through the open end, accepting the round shape of the …

Extrusion may be defined as a process for making a product (an extrudate) by forcing a material through an orifice or die to form a shape, or alternatively, the production of finished, or semi-finished …

Aluminum Extrusion Process The process of extruding aluminum involves 10 basic steps that begin with die preparations and end with secondary operations for surface finishing:

Aluminum extrusion is a process in which hot metal is forced to flow through a shaped opening in a die, creating a final form with specific design charac- teristics.

Whilst extrusion is used for processes as varied as wire coating and film blowing, this document will concentrate on profile extrusion, one of the largest volumes areas for extruded products.
