Description of Extruded Sheet:

Extruded sheet is processed by a machine that pushes a liquified acrylic monomer through a series of rollers. These rollers are designed to flatten and cool the sheets as they run through the extrusion equipment.

This process is the most cost effective form of manufacturing plastic sheet and probably accounts for about 80% of all the clear plastic sheet on the market.

Description of Extruded Sheet:

Cast Sheet is made by pouring a liquid acrylic monomer between two sheets of highly polished glass sealed with a rubber gasket. This unit includes heat activated hardeners, or catalysts, and as the unit is heated, through a series of water baths, produce a single sheet of solid plastic.

What is the Strength Difference?:

Cast plastic sheet is processed with very little stress involved. This results in a stronger sheet material due to the higher molecular structure of the sheet.

Casting the sheet is a more time consuming and more expensive process. This process is mainly used to manufacture thicker sheets and / or when the sheet material is going to be used in an application where strength is an issue, such as aircraft canopies, aquariums, water tanks etc, or where the sheet material needs to be fabricated using machines. Basically cast sheet is harder than extruded sheet.

If you attempt to machine extruded plastic the heat created from the machining tends to release any stress put in the material at manufacturing stage when the force of the rollers compacted the material to make it thinner.

You will not have this problem with cast sheet since there was no stress introduced during the manufacturing process. However, one of the benefits of extruded sheet over cast sheet is that greater thickness tolerances can be achieved during the extrusion process than can be achieved in the casting process.
