Cast Acrylic Sheet Thickness Tolerance

Cast tolerances are determined by sheet size.

Cast acrylic sheet thickness tolerance. These sheets vary more than any other plastic and can be 20 or more. This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass. Tolerances apply both to smooth and velvet texture acrylite satinice cast products. The sheet is optically superior when viewed though the surface.

Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet. It is thermo formable and can be reworked hot which is not always possible with extruded sheets. Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance. Beyond 25 mm acrylite is cast to a corporate thickness specifications.

Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. Thickness tolerances for acrylic sheet here are the tolerances on the thickness of the acrylic sheets that we offer. This material meets pvho requirements. These are general guidelines for thickness tolerances on plexiglass acrylic sheets.

36 x 60 40 x 50 48 x 96 sheets 236 thinner. Iso 7823 1 provides thickness tolerances up to 25 mm. We have assigned class 1 2 and 3 to differentiate sheet sizes. What are the tolerances for plexiglas mc acrylic sheet thickness cut width and flatness.

Check here for the exceptions. Exact thickness tolerances will vary by manufacturer. However polished edges may show the original casting surfaces as lines. Beyond 25 mm acrylite is cast to a corporate.

Please call us at 858 560 1551 with any questions. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. As an example cast acrylic sheet is poured between 2 sheets of glass. Sheet thicker than 4 500 is available as composite casting.

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. As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension. Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness. The table below covers a range of standard thicknesses we produce from 3 0 mm to 150 mm.

Class 1 sheet sizes. Cast plexiglass acrylic has a less consistent sheet thickness with up to 10 variation possible across the panel. The thickness tolerance for most colorless plexiglas mc sheet is 5 10.
