Cast Acrylic Sheet Vs Extruded

In addition cast acrylic when laser cut produce a highly polished edge thus reducing finishing times when fabricating.

Cast acrylic sheet vs extruded.

Furthermore when hot wire line bending drape or vacuum forming cast acrylic sheets are more malleable pliable than extruded acrylic sheet. For each sheet made a gasketed glass cell must be assembled. Acrylic is manufactured in two versions cast and extruded. Extruded acrylic costs less than cast and is more dimensionally stable meaning the thickness is more consistent across sheets.

The cell cast process manufactures individual sheets of acrylic. The edges on extruded acrylic parts can look a bit different depending on the direction of the acrylic extrusion. When laser cutting extruded acrylic there will come a burr on one side of the part. Cast acrylic is made by pouring the hot liquid acrylic ingredients between two sheets of glass which are separated by rubber gaskets the thickness of the gasket determines the thickness of the acrylic sheet being made.

Essentially liquid monomer unreacted acrylic is poured between two panes of glass which are separated by a gasket to control the thickness of the sheet. With a slightly harder surface than extruded cast acrylic has a less consistent sheet thickness with up to a 10 variation possible across the sheet. On the cast acrylic there is almost no burrs. It is thermo formable and can be reworked hot which is not always possible with extruded sheets.

The cells are stacked on a vertical rack and put. Both extruded and cast acrylic sheets comply with fda requirements for food contact which also makes it an ideal choice for restaurants retail stores grocery stores cafeterias and much more. The main difference between cast acrylic and extruded acrylic is that cast acrylic is produced by mixing the acrylic liquid ingredients in molds whereas extruded acrylic is produced by an extrusion method. Cast acrylic is more resistant to the same solvents.
