Cast Acrylic Sheet Thickness Tolerance

We have assigned class 1 2 and 3 to differentiate sheet sizes.

Cast acrylic sheet thickness tolerance.

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. Thickness tolerances of acrylic sheet. Exact thickness tolerances will vary by manufacturer.

Beyond 25 mm acrylite is cast to a corporate. These sheets vary more than any other plastic and can be 20 or more. Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics.

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. The thickness tolerance for most colorless plexiglas mc sheet is 5 10. What are the tolerances for plexiglas mc acrylic sheet thickness cut width and flatness. Please call us at 858 560 1551 with any questions.

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. Class 1 sheet sizes. However polished edges may show the original casting surfaces as lines.

Check here for the exceptions. Tolerances apply both to smooth and velvet texture acrylite satinice cast products. Beyond 25 mm acrylite is cast to a corporate thickness specifications. Iso 7823 1 provides thickness tolerances up to 25 mm.

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. 36 x 60 40 x 50 48 x 96 sheets 236 thinner. This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass.

Sheet thicker than 4 500 is available as composite casting. These are general guidelines for thickness tolerances on plexiglass acrylic sheets. Cast tolerances are determined by sheet size. The sheet is optically superior when viewed though the surface.

Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance. As an example cast acrylic sheet is poured between 2 sheets of glass. As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension.
