Cast Acrylic Sheet Thickness Tolerance

As an example cast acrylic sheet is poured between 2 sheets of glass.

Cast acrylic sheet thickness tolerance.

However polished edges may show the original casting surfaces as lines. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. Cast plexiglass acrylic has a less consistent sheet thickness with up to 10 variation possible across the panel. These sheets vary more than any other plastic and can be 20 or more.

We have assigned class 1 2 and 3 to differentiate sheet sizes. 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. These are general guidelines for thickness tolerances on plexiglass acrylic sheets.

This material meets pvho requirements. Sheet thicker than 4 500 is available as composite casting. Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet. Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance.

The sheet is optically superior when viewed though the surface. Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass. Class 1 sheet sizes.

Exact thickness tolerances will vary by manufacturer. The thickness tolerance for most colorless plexiglas mc sheet is 5 10. As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension. Beyond 25 mm acrylite is cast to a corporate thickness specifications.

Thickness tolerances of acrylic sheet. It is thermo formable and can be reworked hot which is not always possible with extruded sheets. Please call us at 858 560 1551 with any questions. Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness.

Beyond 25 mm acrylite is cast to a corporate. The table below covers a range of standard thicknesses we produce from 3 0 mm to 150 mm. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. Iso 7823 1 provides thickness tolerances up to 25 mm.

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. Cast tolerances are determined by sheet size. Iso 7823 1 provides thickness tolerances up to 25 mm.
