Cast Acrylic Sheet Thickness Tolerance

This material meets pvho requirements.

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. We have assigned class 1 2 and 3 to differentiate sheet sizes. 36 x 60 40 x 50 48 x 96 sheets 236 thinner. Iso 7823 1 provides thickness tolerances up to 25 mm.

These sheets vary more than any other plastic and can be 20 or more. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. However polished edges may show the original casting surfaces as lines. Beyond 25 mm acrylite is cast to a corporate.

Thickness tolerances for acrylic sheet here are the tolerances on the thickness of the acrylic sheets that we offer. The thickness tolerance for most colorless plexiglas mc sheet is 5 10. Beyond 25 mm acrylite is cast to a corporate thickness specifications. It is thermo formable and can be reworked hot which is not always possible with extruded sheets.

Iso 7823 1 provides thickness tolerances up to 25 mm. Whilst cast acrylic sheets tend to have a greater variance on thickness tolerance as much as 30 on thickness. Acrylite cast gp acrylic sheet is manufactured according to iso 7823 1 plastics poly methyl methacrylate sheets types dimensions and characteristics. Tolerances apply both to smooth and velvet texture acrylite satinice cast products.

The sheet is optically superior when viewed though the surface. Class 1 sheet sizes. Close tolerance sheet maintains closer thickness tolerances than standard commercial grade sheet. Check here for the exceptions.

The table below covers a range of standard thicknesses we produce from 3 0 mm to 150 mm. As manufactured the flatness tolerance of plexiglas mc sheet depends on the long dimension. 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.

Thickness tolerances of acrylic sheet. Larger sheets have greater variance across a sheet and smaller sheets will hold a tighter tolerance. Exact thickness tolerances will vary by manufacturer. These are general guidelines for thickness tolerances on plexiglass acrylic sheets.

What are the tolerances for plexiglas mc acrylic sheet thickness cut width and flatness. Please call us at 858 560 1551 with any questions. Cast plexiglass acrylic has a less consistent sheet thickness with up to 10 variation possible across the panel.
