1. Extruders

“There are many different variations of extrusion equipment. They vary by four major characteristics:

Movement of the extrusion with relation to the ram. If the die is held stationary and the ram moves towards it then its called "direct extrusion". If the ram is held stationary and the die moves towards the ram its called "indirect extrusion.

The position of the press, either vertical or horizontal.

The type of drive, either hydraulic or mechanical. 

The type of load applied, either conventional (variable) or hydrostatic

A single or twin screw auger, powered by an electric motor, or a ram, driven by hydraulic pressure (often used for steel and titanium alloys), oil pressure (for aluminium), or in other specialized processes such as rollers inside a perforated drum for the production of many simultaneous streams of material.”
