Cast Acrylic Sheet Thickness Tolerance

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

Cast acrylic sheet thickness tolerance.

36 x 60 40 x 50 48 x 96 sheets 236 thinner. Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. These are general guidelines for thickness tolerances on plexiglass acrylic sheets. Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness.

Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance. Thickness tolerances of acrylic sheet. Cast tolerances are determined by sheet size. 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. However polished edges may show the original casting surfaces as lines. This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass. As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension.

Class 1 sheet sizes. Sheet thicker than 4 500 is available as composite casting. Check here for the exceptions. As an example cast acrylic sheet is poured between 2 sheets of glass.

Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. What are the tolerances for plexiglas mc acrylic sheet thickness cut width and flatness. Iso 7823 1 provides thickness tolerances up to 25 mm. Beyond 25 mm acrylite is cast to a corporate.

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. This material meets pvho requirements. Thickness tolerances for acrylic sheet here are the tolerances on the thickness of the acrylic sheets that we offer. Iso 7823 1 provides thickness tolerances up to 25 mm.

The table below covers a range of standard thicknesses we produce from 3 0 mm to 150 mm. Tolerances apply both to smooth and velvet texture acrylite satinice cast products. Exact thickness tolerances will vary by manufacturer. The thickness tolerance for most colorless plexiglas mc sheet is 5 10.

Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. We have assigned class 1 2 and 3 to differentiate sheet sizes.
