We have assigned class 1 2 and 3 to differentiate sheet sizes.
Cast acrylic sheet thickness tolerance.
Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets.
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.
These sheets vary more than any other plastic and can be 20 or more.
It is thermo formable and can be reworked hot which is not always possible with extruded sheets.
As an example cast acrylic sheet is poured between 2 sheets of glass.
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.
Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet.
The table below covers a range of standard thicknesses we produce from 3 0 mm to 150 mm.
Cast tolerances are determined by sheet size.
Beyond 25 mm acrylite is cast to a corporate.
The thickness tolerance for most colorless plexiglas mc sheet is 5 10.
Class 1 sheet sizes.
Please call us at 858 560 1551 with any questions.
Exact thickness tolerances will vary by manufacturer.
However polished edges may show the original casting surfaces as lines.
What are the tolerances for plexiglas mc acrylic sheet thickness cut width and flatness.
36 x 60 40 x 50 48 x 96 sheets 236 thinner.
Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics.
Sheet thicker than 4 500 is available as composite casting.
Thickness tolerances of acrylic sheet.
Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness.
The sheet is optically superior when viewed though the surface.
Tolerances apply both to smooth and velvet texture acrylite satinice cast products.
As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension.
Iso 7823 1 provides thickness tolerances up to 25 mm.
Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance.
This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass.
Check here for the exceptions.
Beyond 25 mm acrylite is cast to a corporate thickness specifications.
Thickness tolerances for acrylic sheet here are the tolerances on the thickness of the acrylic sheets that we offer.
