Aluminum Extrusion Process: A Detailed Breakdown
Aluminum extrusion is a technique of forcing aluminum alloy material into a die having a predetermined cross-sectional shape. A substantial ram pushes the aluminum via the die and exits from the die aperture. It emerges in the exact form of the die and is hauled off along a runout table when this happens.
PLASTIC EXTRUSION PROCESS
A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...
