Cast Acrylic Sheet Thickness Tolerance

The table below covers a range of standard thicknesses we produce from 3 0 mm to 150 mm.

Cast acrylic sheet thickness tolerance.

These are general guidelines for thickness tolerances on plexiglass acrylic sheets. Beyond 25 mm acrylite is cast to a corporate. Check here for the exceptions. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics.

36 x 60 40 x 50 48 x 96 sheets 236 thinner. The thickness tolerance for most colorless plexiglas mc sheet is 5 10. Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance. However polished edges may show the original casting surfaces as lines.

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. Cast tolerances are determined by sheet size. Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness.

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. It is thermo formable and can be reworked hot which is not always possible with extruded sheets. Sheet thicker than 4 500 is available as composite casting. 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. Sizes 1 16 3 8 are the extruded sheets and the 1 2 3 4 and 1 are the cast sheets. The sheet is optically superior when viewed though the surface. Iso 7823 1 provides thickness tolerances up to 25 mm.

Beyond 25 mm acrylite is cast to a corporate thickness specifications. As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension. This material meets pvho requirements. Exact thickness tolerances will vary by manufacturer.

Thickness tolerances of acrylic sheet. Class 1 sheet sizes. Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet. Please call us at 858 560 1551 with any questions.

This is compensated by the surface finish as smooth as glass since it was cast or molded between two sheet of glass. These sheets vary more than any other plastic and can be 20 or more. Cast plexiglass acrylic has a less consistent sheet thickness with up to 10 variation possible across the panel.
