Cast Acrylic Sheet Thickness Tolerance

These sheets vary more than any other plastic and can be 20 or more.

Cast acrylic sheet thickness tolerance.

Tolerances apply both to smooth and velvet texture acrylite satinice cast products. As an example cast acrylic sheet is poured between 2 sheets of glass. Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet. However polished edges may show the original casting surfaces as lines.

We have assigned class 1 2 and 3 to differentiate sheet sizes. Thickness tolerances of acrylic sheet. Iso 7823 1 provides thickness tolerances up to 25 mm. The thickness tolerance for most colorless plexiglas mc sheet is 5 10.

These are general guidelines for thickness tolerances on plexiglass acrylic sheets. This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass. Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. Sheet thicker than 4 500 is available as composite casting.

Beyond 25 mm acrylite is cast to a corporate. As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension. 36 x 60 40 x 50 48 x 96 sheets 236 thinner. What are the tolerances for plexiglas mc acrylic sheet thickness cut width and flatness.

It is thermo formable and can be reworked hot which is not always possible with extruded sheets. Cast plexiglass acrylic has a less consistent sheet thickness with up to 10 variation possible across the panel. Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance. The table below covers a range of standard thicknesses we produce from 3 0 mm to 150 mm.

Please call us at 858 560 1551 with any questions. Check here for the exceptions. Iso 7823 1 provides thickness tolerances up to 25 mm. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics.

Cast tolerances are determined by sheet size. Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness. This would mean a 1 00 thick sheet could be from 80 1 20 thick within the same sheet and still be within the factory tolerance materials within a factory tolerance can not be returned. Beyond 25 mm acrylite is cast to a corporate thickness specifications.

Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. The sheet is optically superior when viewed though the surface. This material meets pvho requirements.
